ABSTRACT (Maximum 200 words) In this tenth annual legislatively mandated report, 1998 and 1999 DUI data from diverse sources were compiled and cross-referenced for the purpose of developing a single comprehensive DUI data reference and monitoring system. This report presents crosstabulated information on DUI arrests, convictions, court sanctions, administrative actions and alcohol-involved accidents. In addition, this report provides an evaluation of the effectiveness of alternative court and administrative sanctions (including alcohol treatment programs and license actions) upon the 1-year postconviction records of first and second DUI offenders over a time period of nine years. The postconviction driving records of second DUI offenders arrested in 1996 and 1998 were evaluated for three- and one-year periods, respectively. 14.

These totals do not include conviction abstracts not yet received. Thus, for the most recent years, these figures will substantially underestimate the final conviction totals. 3 These data include a projected number of abstracts not yet received. This number is based on an empirically derived function of the court abstract reporting rate. 4 These totals were taken from the Research DUI data file and the DMV annual Suspension and Revocation reports and include late reporting of convictions from prior years. 5 Since 1991, total mandatory suspension/revocation exceeds the number of DUI arrests because many offenders now receive both an APS and postconviction suspension/revocation. 6 This estimated final conviction rate has been adjusted for arrest data known to be missing. 7 The 1997/1998 counts reflect backlogged actions from 1997 that were processed in 1998. 8 These totals include suspension actions that are associated with lack of compliance with statutory requirements. 9 From 1989-1990 these were.10 Implied Consent refusal suspensions/revocations. r Revised from prior reports. i

HIGHLIGHTS OF YEAR 2001 CALIFORNIA DUI-MIS REPORT! Alcohol-involved traffic fatalities increased by 9.1% in 1999, the first annual increase in over a decade.! DUI arrests increased by 188 in 1999, only the second annual increase in the past decade.! The number of persons injured in alcohol-involved accidents declined by 3.7% in 1999 (the thirteenth consecutive year of decline). Since 1989, alcohol-involved injuries have dropped by over half (53.3%).! 12.8% of all 1998 DUI arrests were associated with a reported traffic accident, compared to 12.3% in 1997, 12.6% in 1996, 12.4% in 1995, 13.2% in 1994 and 13.1% in 1993. Almost half (45.5%) of these accidents involved an injury or fatality.! The average blood alcohol concentration (BAC) of a convicted DUI offender, as reported by law enforcement on APS forms, was.163% in 1998 (same as in 1997), which is more than double the California illegal per se BAC limit of.08%.! Among 1999 DUI arrestees, Hispanics (42.3%) no longer constituted the largest racial/ethnic group, being outnumbered by Whites (42.8%) for the first time since 1992. Hispanics, however, continued to be arrested at a rate substantially higher than their estimated percentage of California s adult population (26.5% in 1999). The ethnic distribution among DUI arrestees who are convicted fairly closely parallels the ethnic distribution of the arrestees.! The average age of an arrested DUI offender in 1999 was 33.7 years. Less than 1% of arrested DUI offenders are juveniles (under age 18).! Among convicted DUI offenders in 1998, 73.5% were first offenders and 26.5% were repeat offenders (one or more prior convictions within the previous 7 years). The proportion of repeat offenders has decreased slightly each year since 1989, when it stood at 37%.! 14.4% of 1998 DUI arrest cases did not show any corresponding conviction on DMV records. This is a decrease from 15.8% in 1997 and 18.4% in 1996. iii

! Alcohol treatment, in conjunction with license restriction, continued to be the most effective postconviction sanction in reducing subsequent DUI incidents among DUI offenders. Contrary to last year s findings, second offenders assigned to ignition interlock, in addition to license suspension and alcohol treatment, did show a significantly different 1-year DUI incident rate from that of the SB 38 alcohol treatment group.! DUI recidivism rates have declined by 23.6% to 47.5% since 1990, regardless of sanction group. iv

INTRODUCTION This report is the tenth Annual Report of the California DUI Management Information System, produced in response to Assembly Bill 757 (Friedman), Chapter 450, 1989 legislative session (see Appendix A). This bill required the Department of Motor Vehicles (DMV) to "establish and maintain a data and monitoring system to evaluate the efficacy of intervention programs for persons convicted" of DUI in order to provide "accurate and up-to-date comprehensive statistics" to enhance "the ability of the Legislature to make informed and timely policy decisions." The need for such a data system had long been documented by numerous authorities, including the 1983 Presidential Commission on Drunk Driving. In responding to this legislative mandate, this report combines and cross-references DUI data from diverse sources and presents them in a single reference. Data sources drawn upon include the California Highway Patrol (CHP) for accident data, Department of Justice (DOJ) for arrest data, and the DMV driver record database. Each of these reporting agencies, however, initially draw their data from diffuse primary sources such as individual law enforcement agencies (arrest and accident reports) and the courts (abstracts of conviction). The general conceptual design of the California DUI management information system (DUI-MIS) is presented in Figure 1. The basic theme of the DUI-MIS is to track the processing of offenders through the DUI system from the point of arrest and to identify the frequency with which offenders flow through each branch of the system process (from law enforcement through adjudication to treatment and license control actions). Figure 1 also illustrates the relationship between offender flow and data collection at each point of the process. The initiating data source for the DUI-MIS is the DUI arrest report, as compiled by the DOJ Law Enforcement Information Center's Monthly Arrest and Citation Register (MACR) system. Another major objective of this report is to evaluate the effectiveness of court and administrative sanctions on convicted DUI offenders. This is accomplished by examining the postconviction recidivism records (alcohol/drug-related accidents and traffic convictions) of offenders assigned to alternative sanctions, as detailed in Section 4 on "Postconviction Sanction Effectiveness." 1

It should again be noted that it is not an objective of this report to make recommendations based on the data presented. Rather, the primary purpose of a reporting system such as the DUI-MIS is to provide objective data on the operating and performance characteristics of the system for others to assess in making policy decisions, formulating improvements and conducting more in-depth evaluations. The DUI-MIS data system and report has led to numerous improvements in the California DUI system, from the identification of inappropriate dismissals in a small central valley court to major initiatives to improve the tracking and reporting of DUI cases. The success of the California DUI-MIS has also contributed to a national initiative to design a model DUI reporting system, developed under contract to the National Highway Traffic Safety Administration (NHTSA). 3

SECTION 1: DUI ARRESTS The information presented below on DUI arrests is based primarily on data collected annually by the Department of Justice (DOJ), Law Enforcement Information Center, Monthly Arrest and Citation Register (MACR) system. These data are the most current nonaggregated data available on DUI arrests. Table 1: DUI Arrests by County and Annual Percentage Change from 1997-1999. The number of DUI arrests by county for the years 1997-1999 and the percentage change from 1998-1999 are shown in Table 1. Table 2: 1999 DUI Arrests by County and Type of Arrest. This table shows a breakdown of 1999 DUI arrests by felony, misdemeanor, and juvenile arrest type, by county. The table also shows county and statewide DUI arrest rates per 100 licensed drivers. Tables 3a and 3b: 1999 DUI Arrests by Age, Sex, and Race/Ethnicity. Table 3a crosstabulates age by sex and age by race/ethnicity of 1999 DUI arrestees statewide. The same tabulations by county are found in Appendix Table B1. Table 3b shows the same data crosstabulated by sex and age within race/ethnicity. Figure 2 below displays the trend in DUI arrests from 1989 to 1999. 400000 NUMBER OF DUI ARRESTS 350000 300000 250000 200000 150000 100000 50000 0 Total Felony Misdemeanor 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 YEAR Figure 2. DUI arrests 1989-1999. 4

Based on the data shown in Figure 2 and Tables 1, 2, 3a, and 3b, the following statements can be made about DUI arrests in California: Statewide Parameters:! DUI arrests increased by 188 in 1999 (less than 1%), only the second annual increase of the decade.! The per capita DUI arrest rate was again 0.9 in 1999 (as in 1997 and 1998), which represents a 50% reduction over the 1.8 rate at the beginning of the decade (1990).! Felony DUI arrests (involving bodily injury or death) continue to constitute a relatively small proportion (2.7% in 1999) of all DUI arrests. County Variation:! 22.9% of all 1999 California DUI arrests occurred in Los Angeles County. Four counties (Los Angeles, Orange, San Diego, and San Bernardino) had over 10,000 DUI arrests each, accounting for 44.3% of all arrests.! The 1999 county per capita DUI arrest rates ranged from 0.2 to 2.8 DUI arrests per 100 licensed drivers. Six counties had rates of 0.7 or below. These low per capita arrest rate counties were San Francisco (0.2), Alameda, Mariposa, San Mateo, Santa Clara and Solano (0.7). Three counties had rates of 2.0 or higher Colusa (2.8), Alpine (2.4), and Imperial (2.0).! As in past years, many counties again showed a decline in DUI arrests in 1999. Among the larger counties, the greatest percentage decline occurred in San Francisco (-13.9%), Placer (-11.5%), and San Joaquin (-10.5%). Among smaller counties, the largest percentage decreases in DUI arrests occurred in Trinity (-36.4%) and Alpine (-17.9%). Among counties showing percentage increases in DUI arrests were San Benito (55.5%), Butte (26.0%), Tuolumne (23.5%), Shasta (22.5%), Lake (22.4%), and Glenn (22.3%). Demographic Characteristics:! The average age of a DUI arrestee in 1999 was 33.7 years. Roughly half (46.1%) of all arrestees were age 30 or younger and almost three-quarters (74.8%) were age 40 or younger. Less than 1% of all DUI arrests involved juveniles (under age 18). 2.3% of all arrestees were over age 60.! Males comprised 85.6% of all 1999 DUI arrests. 5

! For the first time since 1992, Hispanics (42.3%) no longer represented the largest ethnic group among DUI arrestees in 1999 (Whites were the largest group at 42.8%). Hispanics, however, continued to be arrested at a rate substantially higher than their estimated 1999 population parity of 26.5% (Department of Finance, Demographic Research and Census Data Center). Blacks were also slightly overrepresented among DUI arrests (6.8% of arrests, 6.7% of the population), while other racial/ethnic groups were underrepresented among DUI arrestees, relative to their estimated 1999 population parity. These underrepresented groups were Whites (42.8% of arrests, 54.9% of the population), and Other (8.0% of arrests, 12.0% of the population). Figure 3 below shows the percentages of 1999 DUI arrests and 1999 estimated census adult population by race/ethnicity.! Among male 1999 DUI arrestees, 45.9% were Hispanic, 39.3% were White, 6.7% were Black, and 8.0% were "Other." Among female DUI arrestees, 63.9% were White, 20.6% were Hispanic, 7.4% were Black, and 8.1% were "Other." The overrepresentation of Hispanics among DUI offenders is clearly limited to males.! In the following 6 counties, Hispanics comprised over 60% of those arrested for DUI during 1999: Tulare (71.9%), Imperial (71.3%), San Benito (68.6%), Fresno (66.6%), Madera (66.5%), and Merced (60.8%). In most other counties, the majority of arrestees were White.! The average age of a DUI arrestee varied considerably by race: Blacks were the oldest with a mean age of 36.3 years, while Hispanics were the youngest, with a mean age of 31.3 years.

SECTION 2: CONVICTIONS Data on convictions resulting from court adjudication of DUI arrests are reported directly to the Department of Motor Vehicles (DMV) on court abstracts of conviction. The following tables compile and crosstabulate these conviction data by demographic, geographic, and adjudicative categories. In what follows, expressions like 1998 convictions refer to DUI offenders arrested in 1998, who were subsequently convicted. Table 4: 1998 DUI Convictions by Age and Sex. This table crosstabulates statewide DUI conviction information by age and sex. Corresponding county-specific conviction data are presented in Appendix Table B2. Table 5: Matchable 1998 DUI Convictions by Age, Race/Ethnicity, and Sex. This table displays DUI conviction information by age, race/ethnicity, and sex. "Matchable" DUI convictions are those which are traceable to a DUI arrest appearing on the MACR system. Because not all arrests could be matched to an existing record, these conviction totals underestimate the total number of actual convictions. Table 6: Adjusted 1998 DUI Conviction Rates and Relative Likelihood of Conviction by Age and Race/Ethnicity. This table shows the relative probability of a DUI arrest leading to a DUI conviction by age and race/ethnicity. DUI conviction totals from categories in Table 5 ("matchable DUI convictions") were increased by the proportion which matchable convictions constituted of "total DUI convictions," shown in Table 7, to arrive at the adjusted DUI conviction rates. As explained above, without this adjustment DUI conviction rates would be underestimated using the conviction data from Table 5 because not all reported convictions are "matchable" to an arrest. Table 7: Total Conviction Data for 1998 DUI Arrestees. This table portrays county and statewide DUI-related conviction data as reported to the DMV on court abstracts of conviction. Corresponding court-specific data are shown in Appendix Table B3. Convictions not reported to DMV are considered nonconvictions for the purposes of this report. Actual nonconvictions include cases where the DUI arrest was not filed, not prosecuted, or resulted in a not guilty verdict. The DUI conviction rates by county were calculated by comparing the county conviction totals with DOJ arrest totals. Because not all 1998 DUI arrests have yet been adjudicated, these conviction totals and rates will slightly underestimate the "final" figures. The DUI conviction rates shown in the "DUI Summary Statistics: 1989-1999" table at the very beginning of this report include an estimate of these late convictions, and thus are slightly higher than those shown in Tables 7 and 8. Conviction variables include felony and misdemeanor DUI convictions, 10

alcohol- and nonalcohol-related reckless driving convictions, convictions of "other" lesser offenses, and DUI convictions dismissed or found unconstitutional. DUI arrest dates from the DOJ MACR system were matched to driver record violation dates to identify nonalcohol-related reckless driving and "other" convictions. The average (mean) adjudication time lags from DUI arrest to conviction, and from conviction to update on the DMV database, were calculated for each county. Table 8: Adjudication Status of 1998 DUI Arrests by County. This table shows the adjudication status (court disposition) of 1998 DUI arrests, by county. Included are the percentages of arrests which have resulted in DUI convictions (misdemeanor or felony), reckless driving convictions (alcohol-related or nonalcohol-related), convictions of "other" offenses, or no reported conviction, as of the date of writing. Again, because not all 1998 DUI arrests have yet been adjudicated, these rates will slightly underestimate the "final" rate for each category, excepting the category "no record of any conviction," which will be slightly reduced (approximately 1-2%) by the eventual adjudication of these few late cases. Table 9a: 1998 Reported Blood Alcohol Concentration (BAC) Levels of DUI Convictions and Table 9b: 1998 Reported Blood Alcohol Concentration (BAC) Levels of Convicted DUI Offenders Under Age 21. Table 9a shows the frequency of reported positive BAC levels for DUI and alcohol-reckless convictions. Because of more complete reporting of BAC levels on APS reporting forms (74.6%) than on abstracts of conviction, those reports are used to calculate statewide BAC levels. Abstracts of conviction, which were used in prior evaluations, report BAC levels in only 56% of cases. Table 9b shows the BAC distribution for convicted arrestees under age 21. Table 10: 1998 DUI Convictions by Offender Status and Average Reported BAC Level. This table displays the proportions of convicted DUI offenders by offender status (number of prior convictions in seven years), and the average (mean) BAC level from APS reporting forms and abstracts of conviction, for each offense level. Figure 4 (below) shows, for the years 1989 to 1999, the number of DUI abstracts received to date by DMV from the courts, the estimated final number of DUI convictions which will ultimately be received, and the estimated final DUI conviction rate. 11

Estimated DUI convictions = see footnote 3 to "DUI Summary Statistics: 1989-1999." Figure 4. DUI abstracts received by DMV and DUI conviction volume and rate estimates, 1989-1999. Based on these data, the following statements can be made: Statewide Adjudication Parameters:! The estimated DUI conviction rate for 1999 arrestees (75%) increased slightly from previous years.! 9.7% of 1998 DUI arrests resulted in reckless driving convictions, and 19.6% of these were not correctly identified as alcohol-related on the abstracts. Both of these rates are slightly lower than corresponding rates for the previous year.! 2.1% of 1998 DUI arrests have resulted in convictions of offenses other than DUI or reckless driving, down slightly from the previous year (2.4%).! 14.4% of 1998 DUI arrests have not yet resulted in any conviction on DMV s records, compared to 15.8% in 1997, 18.5% in 1996, 16.3% in 1995, 18.0% in 1994, 18.8% in 1993 and 19.2% in 1992. As additional cases are adjudicated and reported by the courts, this figure will decrease slightly. 12

! The average reported BAC level for all convicted DUI offenders in 1998, using APS reporting forms as the data source, was 0.163%, which is the same as last year, yet still more than double the illegal per se BAC limit of 0.08%.! Average BAC levels increase as a function of the number of prior DUI convictions, from a 0.160% BAC for a first offense to a 0.183% BAC for a fourth or subsequent offense.! Among 1998 convicted DUI offenders, 73.5% were first offenders, 20.6% were second offenders, 4.6% were third offenders, and 1.3% were on their fourth or more offense. (The statutorily defined time period for counting priors in California is seven years.) The proportion of repeat offenders (26.5%) among all convicted DUI offenders has decreased slightly each year since 1989 (at which time 37% of all convictions were repeat offenses).! The average (mean) adjudication time lags were 2.9 months from DUI arrest to conviction and 2.8 months from conviction to update on the DMV database, totalling almost 6 months from arrest to update on the offender's driving record. This total elapsed time from arrest to update is similar to that in prior years. Variation by County:! Among the larger counties, 1998 DUI conviction rates varied from highs of 87.8% in Orange and 86.0% in Ventura to a low of 56.5% in Fresno. Los Angeles County, which accounted for almost a quarter of all DUI arrests in the state, had a DUI conviction rate of 73.5%.! Among the smaller counties, 1998 DUI conviction rates varied from a high of 87.5% in Tuolumne to a low of 40.5% in Trinity.! The rates at which DUI arrests were plea-bargained to alcohol-related reckless driving convictions varied from over 21% in Nevada County to 0% in Marin, Lassen, and Ventura counties.! The percentage of DUI arrests that were improperly adjudicated as nonalcoholrelated reckless driving convictions varied from 0% to 11.9%. Five counties had rates of 5% or more: Sacramento, Sierra, San Francisco, Butte, and Calaveras. 13

! The percentage of DUI arrests adjudicated as minor convictions ("other" convictions) varied from 0% to 4%. Los Angeles, Alpine, Alameda, San Luis Obispo, and San Bernardino counties had rates of 3% or more.! In six counties, the proportion of arrestees not showing a conviction of any offense exceeded 30%. These counties were Trinity, Sutter, Imperial, Sierra, Mariposa, and Tulare. Twenty-four counties had nonconviction rates of less than 10%, with Tuolumne, Santa Barbara, and Yuba at 2% or less. Variation by Court:! As was true for prior years, the 1999 superior court time lags were generally longer than municipal court time lags, presumably due to the type of DUI case (felony) being adjudicated.! Municipal court time lags from arrest to conviction (for courts with more than a handful of reported convictions) varied from a high of 5.6 months in the Calexico (Imperial County) court to a low of 1.2 months for the Salinas court (Monterey County). Interestingly, the busiest DUI court in the state, Los Angeles Metro, had a time lag from arrest to conviction of only 1.3 months.! Statewide, the proportion of reckless driving convictions (alcohol and nonalcohol), relative to all convictions resulting from DUI arrests, was about 10% in 1998 (as it was in 1997, and down from 11% in 1994 through 1996). Several counties adjudicated more than 20% of their DUI arrests as reckless driving convictions, including Alpine, Mendocino, Nevada, and Yuba.! Statewide, 19.6% of all DUI-related reckless driving convictions in 1998 are inappropriately designated as nonalcohol, down from 21% in 1997. In Sacramento County, however, the Sacramento Court reported 85% (890 out of 1044) of its DUIrelated reckless driving convictions as nonalcohol. Demographic Characteristics:! The average age of a convicted DUI offender in 1998 was 34.9 years.! 41.1% of 1998 DUI convictees were aged 30 years or younger and 72.4% were 40 years or younger. 14

! Females comprised 14.4% of all 1998 convicted DUI offenders, compared to 14.0% in 1997, 13.1% in 1996, 12.8% in 1995, 12.2% in 1994, 12.3% in 1993, 12.1% in 1992, 12.2% in 1991, 11.7% in 1990, and 11.4% in 1989.! The racial/ethnic distribution of 1998 DUI convictions (White = 44.0%; Hispanic = 42.3%; Black = 6.3%; Other = 7.4%) generally paralleled that of 1998 arrests, although Whites were somewhat more likely to be convicted of the offense (as shown in Figure 5 below). 1.2 1.0 1.04 0.98 0.94 0.97 RELATIVE PROBABILITY 0.8 0.6 0.4 0.2 0.0 White Hispanic Black Other Figure 5.

SECTION 3: POSTCONVICTION SANCTIONS Data on court sanctions assigned to convicted DUI offenders were taken from DUI abstracts of conviction for offenders arrested in 1998. Also included are counts of postconviction DMV license actions for selected offender groups, while total counts of all license actions, including administrative per se (APS) license suspensions and revocations, are shown in the Administrative Actions Section. APS actions (effective July 1990) are initiated by law enforcement immediately upon arrest for DUI, and are administered independently of the criminal adjudication process. This section includes the following tables: Table 11: 1998 DUI Court Sanctions by DUI Offender Status. This table shows the frequency of specific court sanctions statewide by number of prior DUI convictions. The specific court sanctions tallied include percentages of probation, jail, alcohol treatment programs (first offender, SB 38 second offender, and 30-month third offender programs), license restriction, court suspension, and ignition interlock. Crosstabulations of sanctions by county, court, and number of prior convictions appear in Appendix Table B4. Table 12: 1998 DUI Sanction Combinations by County - First Offenders. This table displays the frequency of commonly assigned court sanction combinations (such as first offender alcohol program plus license restriction) by county for first DUI offenders. License suspensions include both court and DMV postconviction (non-aps) suspensions. The sanction combination groups portrayed in this table, as well as in Table 13, were defined according to the conventions described in the "Evaluation Methods and Results" portion of Section 4: "Postconviction Sanction Effectiveness." Table 13: 1998 DUI Sanction Combinations by County - Repeat Offenders. This table shows the frequency of commonly assigned court sanction combinations by county for second, third, and fourth (or subsequent) DUI offenders. License actions include both court and DMV postconviction (non-aps) license suspensions and revocations. 22

From the data in these and the Appendix tables, it is evident that the use of alternative sanctions continued to vary widely by county, court, and offender status in 1998. For example: Statewide Parameters:! The most frequently applied court sanction among all convicted DUI offenders was probation (96.5%), while the least frequently used court sanction was court license suspension (5.4%). DUI offenders were sentenced to jail in 75.2% of the cases. (However, in many jurisdictions, jail is often served as community service rather than actual jail time.) Figure 6 (below) graphically displays the statewide data from Table 11 showing the percentage representation of specific types of court-ordered sanctions among all convicted DUI offenders. Because virtually all offenders receive more than one type of sanction, the cumulative percentage adds to much more than 100%. PERCENTAGE 100 75 50 25 96.5 75.2 85.2 48.6 5.4 6.3 0 Probation Jail Treatment program License restriction Court license suspension Ignition interlock Figure 6. Percentage representation of court-ordered DUI sanctions (1998). County Variation:! The proportion of first-dui offenders sentenced to jail varied by county from less than 10% in Marin County to almost 100% in Alameda, Alpine, Amador, Butte, Calaveras, Kings, Lake, Lassen, Monterey, Napa, Plumas, San Joaquin, San Luis Obispo, Shasta, Sutter, Tulare, Tuolumne, and Ventura counties. 23

! Considering sanction combinations, counties such as Amador, Lake, Napa, San Luis Obispo, San Mateo and Sutter preferred to assign first offenders to treatment program and jail (over 85%) rather than treatment program and license restriction (3% or less). In contrast, Humboldt, Marin and Tehama counties assigned treatment program and jail to less than 5% of their first offenders. Inyo, Los Angeles, Marin, and Orange counties assigned treatment program and license restriction to over 75% of first offenders.! Counties departing from using typical first offender sanction combinations were Alpine, Humboldt, and Imperial, as shown by relatively high percentages (over 10%) in the "other" category. ("Other" includes license restriction without treatment program assignment, probation only, and other unofficial nonstatutory sanction combinations.) Court Variation:! Statewide, there can be extreme variation by court in the use of available sanctions for DUI offenders. In Santa Barbara County alone, one court (Santa Maria) assigned jail to 92.8% of all convicted DUI offenders (n = 570), while another court (Lompoc) in the same county assigned jail to only 38.3% of all convicted DUI offenders (n = 300).! In Los Angeles County, three municipal courts (Burbank, Compton and Lancaster) used jail as a sanction in 95% or more of their DUI sentences. On the other hand, three other courts (Hollywood, Malibu and Monrovia) used jail as a sanction in less than 30% of their DUI sentences.! In 1998, Los Angeles was the only county with an active 30-month third offender treatment program. Even within this county, however, assignment of third offenders to this program modality varied by court from highs of 50% of third offenders sentenced in the Beverly Hills, Burbank, and Malibu courts to 0% of such offenders in many other municipal courts within Los Angeles County.! Although courts required only 6.3% of all convicted DUI offenders to install the ignition interlock device statewide in 1998 (the same proportion as in 1997), the Perris court (Riverside County) required over 28% of DUI offenders to use interlock. Statewide, 22.3% of all convicted repeat DUI offenders were assigned to interlock in 1998. 24

Variation by Offender Status:! Less than 70% of 1998 first-dui offenders were sentenced to jail, compared to over 90% of all repeat offenders.! 89% of first DUI-offenders were assigned to alcohol treatment programs, along with 83% of second offenders, 50% of third offenders, and 22% of fourth or more DUI offenders. (By statute, however, all offenders must eventually complete specified alcohol treatment programs in order to be eligible for license reinstatement.)! 4.4% of first-dui offenders and 8.2% of repeat DUI-offenders received court license suspensions in 1998. Since July 1990, all DUI offenders with BAC levels of 0.08% or more are also subject to a 30 day to 1-year administrative license suspension/revocation under the APS law.! Only 22.3% of repeat-dui offenders were assigned ignition interlock in 1998, in spite of the mandatory interlock law for all repeat offenders (AB 2851 - Freidman), which took effect on July 1, 1993. This law was repealed in 1998, and a new ignition interlock law (AB 762 - Torlakson) and program was enacted and implemented July 1, 1999, which established mandatory interlock for DUI suspension/revocation violators, while providing incentives for repeat offenders to reinstate early with interlock.

SECTION 4: POSTCONVICTION SANCTION EFFECTIVENESS This section presents and describes the results of an evaluation assessing the effectiveness of court and administrative sanctions applied to first and second DUI offenders over a time period of nine years. 1 The effectiveness of alternative sanctions for second offenders is evaluated in terms of postconviction driving record as measured by: 1) total accidents and 2) DUI incidents, which include alcohol-involved accidents, major convictions (primarily DUI, also all reckless driving [alcohol or non-alcohol] and hit-and-run), APS (0.08% BAC or chemical test refusal) suspensions and DUI failure-toappear notices (FTA). Displayed below in Figures 7a and 7b are proportions of DUI recidivist incidents over time from 1990 through 1998; these proportions were derived from the sanction analyses for first and second offenders (grouped by sanction assignment) from previous DUI-MIS annual reports and are based on follow-up time periods of one year. The reoffense rates of the 1989 offenders were not included in these figures because their postconviction driving records were not comparable to those of subsequent years, given the significant impact of the implementation of the APS suspension law in 1990. There are typically three variants of first-offender DUI alcohol education/treatment program sanctions, and these were collapsed together into a single sanction group for ease of viewing and interpretation. Figures 7a and 7b do not address total accidents which are displayed later in Figures 8a and 8b. They display covariate-adjusted data which is described below. Figures 9 and 10 similarly displaying covariate-adjusted data, as described below, show the proportion of total accident- or DUI incident-involved second offenders for 1996 and 1998, with follow-up time periods of 3 years and 1 year, respectively. The evaluation of first offenders for these years was not reported at this level of detail because, beginning in 1995, statutory requirements for license reinstatement became homogenous for all first offenders: SB 1295 (1/1/95) mandates all first offenders to attend alcohol treatment programs in order to reinstate their driving privilege, and, since 1990, all offenders are suspended upon DUI arrest under the administrative per se (APS) license suspension law. However, the evaluation for second-dui offenders is 1 Third-or-more offenders were not included because a previous study (Tashima & Marelich, 1989) indicated serious confounding due to group differences on prior interventions. In addition, sanctions for these offenders do not vary much, due to the statutorily prescribed sanction requirements. 29

reported because the ignition interlock sanction is not imposed on all second offenders, and its assessment may contribute to clarifying and perhaps modifying current sanctioning policy. The figures are followed by a narrative description of the evaluation design, subject selection, data collection, analytical procedures, and evaluation results. The reader is cautioned that license suspension (as assessed in this study) refers to postconviction suspensions only, and does not include preconviction administrative per se license suspensions (which are applied to all offender groups). Based on the data represented in Figures 7a, 7b, 8a, and 8b, the following conclusions can be drawn about first- and second-offender sanctions from 1990 to 1998:! One-year recidivism rates for all first-offender sanction groups declined noticeably from 1990 to 1998, with reductions in DUI reoffenses of 47.5% for the suspended group, 42.0% for the jail group, and 23.6% for the combined first-offender DUI treatment groups.! A similar decline is evident in the one-year reoffense rates for the second-offender sanction groups, with recividism decreasing (from 1990 to 1998) by 33.0% for the suspended group, 33.5% for the SB 38/license restriction group, and 29.1% for the other group.! Subsequent one-year accident rates also declined over the 1990-1998 period for both first and second offenders, although at a slower rate than DUI incidents.! The relationship between type of sanction and subsequent DUI reoffense rate has remained relatively constant for first offenders since 1990, with the alcohol treatment and license suspension groups exhibiting the lowest reoffense rates and the jail sanction group, showing significantly higher rates than the other two. 30

Based on the data represented in Figures 9 and 10, which address total accidents as well as DUI-related incidents, the following conclusions can be drawn about second-offender sanctions:! Consistent with eight previous DUI-MIS reports, but contrary to earlier California studies, including the first annual DUI-MIS report (1989 offenders), second offenders suspended in 1998 do not have statistically significantly lower total accident rates than do those offenders assigned to SB 38 treatment programs during the first year following suspension or SB 38 assignment. This finding is probably due to the implementation of administrative per se license suspensions beginning in July, 1990, whereby all second offenders are suspended for one year. For the first time in five years, the suspended group s accident rate was significantly higher than that of the interlock group. However, for the longer 3- year follow-up period, the 1996 suspended group had significantly lower total accident rates than those of all other second offenders.! In 1996 and 1998, second offenders who were suspended had statistically significantly higher proportion of DUI incidents in the subsequent 3-year and 1-year periods (respectively) than did those who received the SB 38 program and license restriction sanction. The percentage increases associated with the license suspension group for the two years (1996 and 1998) were 25.0% and 45.2%, respectively. 35 RATE OF ACCIDENT- OR DUI-INCIDENT-INVOLVEMENT PER 100 DRIVERS 30 25 20 15 10 5 6.64 9.02 8.50 8.96 17.55 14.04 13.52 16.19 0 Suspension SB 38 & restriction ACCIDENTS SB 38/restriction & interlock Other Suspension SB 38 & restriction SB 38/restriction & interlock DUI INCIDENTS Other Figure 9.

Adjusted 1-year accident and DUI incident rates of 1998 second offenders by type of sanction.! Similar to findings of previous evaluations, the SB 38 program/restriction sanction group (with and without the addition of ignition interlock) had significantly lower 1-year subsequent DUI incident rates than those of the other 1998 second offender groups. Contrary to last year s evaluation, the recidivism rate of the ignition interlock group was significantly lower than the rate of the SB 38 group without ignition interlock; but this finding did not appear in the 3-year followup periods of the 1996 and combined 1993 through 1996 groups. EVALUATION METHODS AND RESULTS Subject Selection and Data Collection Convicted DUI offenders were identified from monthly abstract update tapes which contain all DUI conviction data reported to DMV by the courts. In the present study, follow-up data for first and second offenders were compiled from eight previous and current DUI-MIS evaluations. Additional follow-up data for another set of second offenders were evaluated for sanction effectiveness: 1) A 3-year follow-up period for convicted 1996 second offenders who were previously evaluated in the 1999 DUI-MIS report. 2) A 1-year follow-up period for convicted DUI second offenders who were arrested for DUI in 1998. 34

For each year's annual DUI-MIS report, an additional year of DUI data is added to the sanction analyses. In order to simplify the analyses and reporting of results, separate analyses of the 1989 through 1995 and 1997 DUI offenders were not included in this year's evaluation. However, for second offenders, 3-year followup data from the 1993, 1994, 1995 and 1996 files were combined to increase the size of the sanction groups. The conviction date in all cases was considered to be the treatment date for defining prior and subsequent driving record data, because the penalties and sanctions for the DUI offense are typically effective as of that date. Since DUI penalties and sanctions are enhanced as a function of the number of prior DUI and alcohol-related reckless driving convictions within the previous seven years, subjects were selected based on the number of such convictions within the seven years prior to their entry DUI arrest in 1998. For this year s report and all previous DUI-MIS reports, subjects selected for evaluation were: 1) first-dui offenders drivers who had no DUI or alcohol-related reckless driving convictions within the previous seven years, and 2) second-dui offenders drivers who had one DUI or alcohol-related reckless driving conviction within the previous seven years. DUI offenders with felony convictions and chemical test refusal suspensions were not included because their license control penalties are more severe than those of the other second-offender groups. Also excluded were drivers who did not have a full one-year subsequent time period because of late conviction dates, drivers with X license numbers (meaning that no California license number could be found), and drivers with out-of-state ZIP Codes. Altogether, the excluded cases represented 16.5% of the original convicted-offender file. Court sanctions are reported to, and recorded by, DMV in the form of disposition codes on the abstract of conviction. Prior to AB 762 (effective 7/1/99), a convicted DUI offender, especially a first offender, might receive any one of many combinations of individual sanctions, which include jail, fine, license restriction or suspension, alcohol treatment program, or probation. Therefore, in defining postconviction sanction combination groups for the purpose of all previous and the current analyses (prior to 7/1/99), the following conventions were used for first offenders: 1) if suspension (non-aps) was one of the sanctions imposed by DMV or the court, then the offender was included in the suspension group; 2) if suspension (non-aps) was not imposed, but the offender was assigned to an alcohol treatment program, then the offender was included in one of the treatment groups, according to the type of treatment program (first offender or SB 38) and 35

whether they were also sentenced to license restriction or jail; and 3) if neither suspension nor treatment was imposed, but the offender was sentenced to jail, then the offender was included in the jail-only group. Fine and probation are generally imposed on most DUI offenders (except that probation is not usually granted to court-suspended first offenders), and for that reason are not included as sanctions evaluated in this report. Also, since July 1990, virtually all DUI offenders have had their licenses administratively suspended upon DUI arrest, so only non-aps suspension was considered. Beginning July 1, 1999, under AB 762, courts may no longer discretionarily impose a six-month license suspension for first offenders under the probation option with the 48-hour jail term; this suspension is now mandatory. This means that the jail-only group will now have their licenses suspended, and license restriction or suspension would be imposed on drivers in the program-jail group. These changes should be evident in next year s report. It should be noted that the definition of the sanction combination groups was not an arbitrary analytical convention, but rather a reflection of the most common naturally occurring sanction combinations assigned by the courts. Based on the above taxonomy, the following five first-offender sanction combination groups were evaluated separately in prior reports: 1) license suspension, 2) jail, 3) first-offender treatment program plus jail, 4) first-offender treatment program plus license restriction, and 5) SB 38 (second offender) treatment program plus license restriction (since some courts assign this sanction combination to a small number of first offenders). For the 1990-1998 overview analysis presented in this year s report, the three treatmentprogram groups were combined into one group. Nevertheless, when compared individually, the subsequent driving records of the separate treatment groups exhibited a very similar pattern, as was evident in prior DUI-MIS reports. A similar convention was used for grouping second offenders with various sanction combinations. The groups used in this analysis are: 1) (post-conviction) license suspension, 2) SB 38 treatment program plus license restriction, 3) a group of 1996 and 1998 second offenders ("other") who did not meet the selection criteria for groups 1 or 2 but were not ordered to install interlock, and 4) a group of 1996 and 1998 second offenders who were ordered to install an ignition interlock device in their vehicles as mandated by AB 2851 (implemented July 1993, but effectively abolished by AB 762, effective July 1999). This device requires that the offender blow into it prior to starting the vehicle, which will not start if he/she has a BAC above a specified level. The interlock group was identified by certain Vehicle Code designations on their abstract of 36

conviction. In examining these abstract disposition codes, it was found that 88.8% of interlock cases were also referred to SB 38 treatment programs (with license restrictions), while 38.5% had their licenses suspended (non-aps); of those that were suspended, 78.5% were assigned to SB 38 treatment programs and less than 1% were assigned to first-offender programs. All second offenders who were assigned to install interlock are included in this evaluation, irrespective of other sanctions and regardless of actual installation. This is reflective of the real world conditions under which interlock is assigned, which is an integral part of the total impact of this sanction. 2 The group designated as "other" represent offenders who were originally referred to an SB 38 treatment program but were suspended as well, either by intent (court sentence to both treatment program and suspension), or omission (court misreporting of disposition codes and/or the offender's lack of compliance with required procedures, such as failure to provide proof of insurance, program enrollment, pay fees, etc.). Even if the courts amend the abstracts of conviction, the offenders still need to meet the insurance and program enrollment requirements. The final sanctions ultimately received by this group are unclear, which makes interpretation difficult. This difficulty is further exacerbated by strong self-selection biases, such as inability or unwillingness to obtain insurance, which make this group different from the others. Prior driver record data were extracted for the 2 years preceding an offender's DUI conviction date. Appendix Tables B5 and B6 list the prior driver record variables for the second offenders, which were used as covariates in the analyses. The evaluation period for the postconviction driving measures, starting from the conviction date, was three years for the 1996 drivers, and one year for the 1998 drivers. A buffer period of six months was allowed between the end of the evaluation period and the data extraction date to allow for processing and reporting of the most recent data to DMV. DUI offenders who had less than the full follow-up time period (from conviction date to the buffer period) were excluded. The outcome driving record measures consisted of the proportion of offenders who were involved in: 1) all accidents and 2) DUI incidents (alcohol-involved accidents, major convictions, APS/refusal suspensions, or DUI failures-to-appear). Evaluation Design and Analytical Procedures Logistic regression analysis was used to evaluate the differences in the proportion of accident- and DUI-incident-involved drivers in each sanction group at the end of the 2 It should be noted, however, that a 1993 policy directive from DMV to the courts originally requested that only offenders who had shown proof of installation be reported as assigned to interlock. To the extent that this directive was followed by the courts (and there is evidence that it was not), the present evaluation would be assessing only those cases where the device was actually installed. This DMV policy directive has since been corrected. 37

evaluation period. Only the first accident or DUI incident or "failure" was evaluated. This is not an important limitation with these data because the incidence of repeat failures (two or more accidents or DUI incidents) was very low over the study time window. More importantly, analysis of repeat failures would be subject to confounding by court sanctions received in connection with the first failure incident. This type of confounding is avoided because multiple incidents were not included in this analysis. Since it was not possible to randomly assign drivers to the various sanction groups, potential biases due to preexisting group differences were statistically controlled to the extent possible by entering into the analyses as covariates biographical data, prior driving record data, and ZIP Code indices (accident and traffic conviction averages for each driver's ZIP Code area and selected ZIP Code variables from the 1990 census data for driver files prior to 1997). Among the traffic conviction averages, only the moving violation averages were used this year, after discovering an undercount of major convictions. Both the traffic safety and census ZIP Code variables were used for the 1996 drivers; but only the traffic safety ZIP Code averages were used for the 1998 drivers, since the 1990 census variables are outdated for these drivers. (Tables B5 and B6 show significant group differences on most of these variables.) While this "quasiexperimental" design is subject to a number of limitations in assessing cause-effect relationships, the attempt at statistical control of group differences removes at least part of the bias in group assignment and provides a more precise estimate of the relationship between type of sanction and subsequent record. It is likely, of course, that the groups also differ on characteristics not measured by, or reflected in, the covariates. The possibility of uncontrolled biases becomes particularly problematic if sanctions are commonly received by atypical offenders through self- or judicial-selectivity (e.g., drivers of higher socio-economic status may be more likely to receive program with restriction and less likely to receive jail than those of lower status). 38

In the 1998 second offender analyses and in the combined 1993, 1994, 1995, and 1996 second-offender analysis for accidents and DUI incidents, one or two statistically significant (p <.01) covariate by sanction interactions were evident. (Statistical significance at p <.0x means that a differential effect between groups would occur by chance less than x% of the time.) These significant interactions indicated that the relationship between the covariates and the outcome measure (DUI incidents) varied across sanction groups. However, in these analyses, where sanction differences were significant (p <.06), the interaction effect was less than one-fourth the main effect of sanction (chi-squares were divided by their respective degrees of freedom to provide an approximate measure of effect size). Since the sanction main effect had substantially greater magnitude than the interaction effect, conclusions about sanction differences were based on analyses that did not include the interactions. One-Year Recidivism Rates for First and Second Offenders, by Sanctions, from 1990-1998 The one-year subsequent DUI-incident reoffense rates for both first- and secondoffender sanction groups were compiled from the eight previous and current annual DUI-MIS evaluations and configured onto two separate graphs to display these rates over time. Figures 7a and 7b show the proportions of first- and second-offender sanction groups, respectively, arrested between 1990 and 1998 who reoffended within one year after conviction. As discussed above, the reoffense rates of these sanction groups were statistically adjusted for group differences related to available covariates. The DUI incidents include alcohol-involved accidents, major convictions (primarily DUI, reckless driving and hit-and-run), APS (0.08% BAC or chemical test refusal) suspensions and DUI failure-to-appear notices (FTA). Figure 7a and Table 14a reveal a continuous decline in the one-year recidivism rates for all of the first offender sanction groups from 1990 to 1998. This overall decline translates into a 47.5% reduction in recidivism for the suspension group, a 42.0% drop for the jail group, and a 23.6% decrease for the alcohol-treatment group. The recidivism rates of the suspended and alcohol program groups continue to appear quite similar, but the decline over time for the suspended group is actually higher (47.5%) than for the treatment group (23.6%). Also, in the earlier years, the combined alcoholtreatment group exhibited lower reoffense rates than did the suspended group, possibly due to the initial impact of APS suspensions on a group that had previously avoided license suspension. However, midway in 1994, the rates of the two groups merge and the downward trend of both groups diminishes. Over the last four years, the suspended group s rate oscillates, but basically shows a leveling of its rate. In 1998, the rate for the alcohol-treatment group flattens out, while the rate for the suspended 39

group shows a downward trend (these two groups together comprise about 95% of first offenders.)

In the more recent years, the recidivism rate declines slightly through 1997, and the rate becomes flat in 1998; overall, these first offenders perform more poorly than the other sanction groups. This could reflect the fact that jail (or community service) is less effective than other sanctions, but it is also likely that uncontrolled selection biases are operating. A similar overall decline is evident in the one-year reoffense rates for the secondoffender groups as displayed in Figure 7b and Table 14a, but the rate of decline is virtually the same for all three groups. From 1996 to 1998, the recidivism rates begin to flatten, reflecting just slightly increased rates in 1998 among the suspended group, SB 38 and other groups, but a declining rate for the ignition interlock group. Table 14a shows that, from 1990 to 1998, the reoffense rates decreased 33.5% for the SB 38 group, 33.0% for the suspended group, and 29.1% for the other group. Obviously, a rate change over the 1990 to 1998 time period is not available for the ignition interlock group since this sanction was rarely applied to second offenders before 1993; the overall reoffense rate for this group is slightly lower than that of the SB 38 program 40

group. The differences in rates between second-offender sanction groups remain relatively steady across the years and, like those for first offenders, may reflect uncontrolled self- or judicial-selection group differences. This is particularly likely for the ignition interlock group, given the cost of installing and maintaining the device. Previous DUI-MIS reports have suggested that, while many factors may be associated with the overall decline in DUI incidents for both first and second offenders, the reduction is probably attributable to the implementation of APS suspensions in 1990. An evaluation (Rogers, 1997) of the California APS Law, in fact, documents recidivism reductions of up to 21.1% for first offenders and 19.5% for repeat offenders which are attributable to the law. One-Year Accident Rates for First and Second Offenders, by Sanctions, from 1990-1998: The one-year subsequent accident rates for both first and second offenders were also compiled from previous and current DUI-MIS evaluations and graphically displayed over time, just as the subsequent DUI-incident reoffense rates were portrayed. Figures 8a and 8b show the proportions of 1990-1998 first- and second-offenders who had accidents within one year after their conviction. Statistical adjustments for group differences were made on these accident rates based on available covariates. TABLE 14b: ONE-YEAR PERCENTAGES OF ACCIDENT-INVOLVED FIRST AND SECOND OFFENDERS, BY TYPE OF SANCTION, 1990-1998 FIRST-DUI OFFENDERS SECOND-DUI OFFENDERS YEAR 1ST OFFENDER SB 38 IGNITION SUSPENDED JAIL PROGRAM SUSPENDED RESTRICTED INTERLOCK OTHER 1990 4.27 5.66 5.09 3.82 3.78 0.00 3.97 1991 4.17 5.86 4.64 3.51 3.60 0.00 3.57 1992 3.51 5.70 4.36 3.70 3.33 0.00 3.52 1993 3.60 5.12 4.47 3.84 3.23 3.01 3.77 1994 3.52 5.82 4.36 3.24 2.82 2.85 3.32 1995 3.13 5.69 4.53 3.08 2.82 2.62 3.14 1996 2.73 4.79 4.42 2.38 2.42 2.56 2.31 1997 3.09 4.82 4.69 2.70 2.50 2.51 2.90 1998 2.80 4.40 4.82 3.09 2.51 2.12 2.76 % DIFFERENCE 1990-1998 -34.4% -22.3% -5.3% -19.1% -33.6% NA -30.5% 41

Among first offenders from 1990 through 1998, Figure 8a and Table 14b show a smaller decline in accident rates overall than was evident among the reoffense rates. The accident rate of the suspended group showed the largest decline of 34.4% from 1990 to 1998, while the jail group had 22.3% fewer accidents over the same time period. On the other hand, the accident rate of the first offender program participants reflects only a 5.3% decline overall; their accident rate has even increased slightly during the last two years. Of the three groups, the suspended group consistently has the lowest accident rate throughout the nine years, while the jail group shows the highest level of accidentinvolvement. Although all groups were suspended/restricted under APS, differences in accident rates probably reflect uncontrolled self- or judicial-selection group differences. Figure 8b also indicates a declining trend in the overall accident rate of second offenders. The greatest decline was evident among the SB 38/restricted group with a 33.6% drop in accidents, while the suspended group had the lowest (19.1%) reduction in accidents. The other group shows a 30.5% difference in their accident rate from 1990 to 1998. The ignition interlock group displays a consistent decline in accidents since 1993, followed by a greater decline from 1997 to 1998. Oddly, the accident rates of the other three groups increased since 1996. The range of differences in accident rates between the four groups is smaller than that of first offenders and overall, second offenders have lower accident rates than do first offenders (Table 14b). The fact that second offenders have fewer accidents than first offenders has been well documented in past evaluations; it has been speculated that the lower accident rate of second offenders may be related to the longer-term (one to two years) license (restriction/suspension) actions imposed on second offenders. Results of the Second-Offender Sanction Evaluation Total Accidents: Results of the 1998 one-year analyses (see Figures 9 and 10, Tables 15 and 16) were quite different from those of the 1990-1997 one-year analyses (contained in the previous eight DUI-MIS reports) in that significant (p =.015) differences on total accidents were evident among the second offender sanction groups. Surprisingly, the suspended group had the highest accident rate, and it was significantly different from the rates of the ignition interlock group (p =.001), but it was not significantly higher (directionally significant at p =.09) than the rate of the SB 38/restricted license group. Overall, since 1990, the accident rates of all the groups have been declining, but within the last two years, the suspended group s accident rate has risen, while the rates of the other three groups have either leveled out or declined. This suggests that the long term effectiveness of the APS one-year license suspension period may continue to limit accidents among the three groups. However, reasons for the increase in accidents among the (non-aps) suspended group are not clear and may be specific only to 42

second offenders evaluated from these two years; other reasons may become more apparent from future analyses. However, the evaluations of the 3-year follow-up periods show quite different results from those of the 1-year time periods. Similar to the 1994 and 1995 3-year follow-up evaluations from the last two years, but in contrast to the 1992 and 1993 3-year analyses, significant sanction group differences on accident rates were evident among the 1996 second offenders. The accident rate of the suspended group continues to be significantly lower than that of the other three groups, suggesting that over a longer period of time (3 years), post-conviction suspension (of 18 months to 2 years duration) has a greater impact in reducing accidents than do other sanctions. The accident rates between the ignition interlock and the SB 38 program groups were not significantly different from each other; this finding was similarly reported in previous 1- and 3-year analyses on accidents in which ignition interlock was one of the sanction groups.

and 1996 3-year second-offender files were combined. Results from this analysis are shown in Tables 15 and 16. Differences in accident rates between sanctions were statistically significant (p =.000). The accident rate of the suspension group was significantly lower than those of all other groups, and the other group had the highest accident rate of all groups. Again, the accident rate difference between the SB 38 program and ignition interlock groups was not significant (p =.23). Also shown in Tables 15 and 16 are the results from last year s analysis combining four years (1993, 1994, 1995, and 1996) of 1-year subsequent accidents and DUI incidents. Additional data were not included nor were any new analyses conducted. These figures are shown here primarily for comparison purposes.

DUI Incidents: Figures 9 and 10 and Tables 15 and 16 show that in both years the suspended groups had significantly higher failure rates (by 25% and 45.2% for 1996 and 1998, respectively) than corresponding rates for the SB 38 program/restricted participants. The group "other" in the 1996 and 1998 analyses had failure rates midway between the suspended group and SB 38 program/restricted group. Failure rates of all four groups in 1996 (3-year follow-up period) were significantly different from each other except that the recidivism rate of the interlock group was not significantly lower than that of the SB 38 group. Also, the 3-year recidivism rates of the SB 38 group and the interlock group were significantly lower than those of the suspension and other groups. In contrast to last year s 1997 analysis, the 1-year recidivism rate of the interlock group was significantly lower than that of the SB 38 program group, but both groups had rates that were significantly lower than those of the suspended and other groups. Similar findings were evident in the combined 1993-1996 analyses over a 3-year followup period, except that reoffense rates between the ignition interlock and SB 38 groups were not significantly different. In summary, findings from the 1998 second-offender analyses were somewhat different from previous post-aps one-year evaluations of second offenders in showing evidence of significant differences between the sanction groups on subsequent total accident rates; the ignition interlock group had the lowest accident rate compared to rates of the suspended and other groups, but not with the SB 38 group. Similar to last years findings from the 3-year accident analyses, the 3-year accident rate of the 1996 suspended group was significantly lower than those of the other groups. The fact that both the 1- and 3-year accident rates in these analyses are the lowest found to date could reflect the ongoing impact of APS suspensions over time, since all second offenders since 1990 are suspended under APS for the duration of the one-year followup period. The results on DUI reoffense rates for second offenders continue to be consistent with the findings of prior studies on alcohol-related incidents, indicating that SB 38 programs with license restriction and with interlock are associated with a reduction in subsequent DUI incidents over both follow-up periods. 45

SECTION 5: ADMINISTRATIVE ACTIONS Data on DMV administrative license disqualification actions (license suspension or revocation S/R) taken in DUI cases are presented below. These statutorily mandated actions, which are taken in cases of alcohol-impaired driving, are initiated by the receipt of either a law enforcement APS report (.08% BAC, zero tolerance, or chemical test refusal) or court abstract of conviction. It should be noted that multiple actions can result from a single DUI incident for example, a single DUI arrest frequently will result in both an APS suspension and a (later) mandatory postconviction suspension action. This section includes the following tables and figure: Table 17: Mandatory DUI License Disqualification Actions, 1989-1999. This table shows preconviction (APS) and postconviction license disqualification totals from 1989 through 1999. The postconviction totals include juvenile suspensions, first-offender suspensions, second-offender suspensions and revocations, and third- and fourth-offender revocations.

This figure graphically portrays mandatory DUI license disqualification totals from 1989 through 1999, both preconviction and postconviction. The following statements are based on the data shown in Tables 17-18 and Figure 11.! During 1991, the first full calendar year of APS license suspension, the total number of DMV DUI preconviction and postconviction S/R actions increased by 60% over that for 1990. These totals have declined each year since then (including a 1% decline in 1999), with the exception of 1996 (2% increase) and 1998 (16% increase). In spite of the substantial 1998 increase, total DUI suspension/revocation actions (through 1999) have still declined by 36.7% since 1991.! In 1999, 179,332 APS license actions were taken. Of these actions, 76.6% were firstoffender actions and 23.4% were repeat-offender actions. 46

! In FY 99/00, APS actions decreased by 2.0%, following a 4.8% increase the previous fiscal year.! Chemical test refusal actions dropped by 5.0% in 1999, following a 1.7% decline in 1998. The total number of refusal actions has fallen 55.7% from the 1991 totals.! The number of mandatory postconviction license actions has declined by 43.7% since 1991.! In the first decade since APS was implemented in July 1990, over two million (2,127,023) APS suspension or revocation actions had been taken.! Requests for APS hearings have increased from 7.1% of all APS actions in FY 90/91 to 21.8% in 99/00. The rate at which APS suspension/revocation actions are upheld after hearing has risen to 88.3% in 99/00, after falling to only 67% in 95/96.! During the first 6.5 years after implementation (on January 1, 1994) of the "zero tolerance" law for minors, 81,942 suspension actions were taken. 500000 450000 400000 350000 300000 250000 200000 150000 100000 50000 0 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 Figure 11.

SECTION 6: ACCIDENTS INVOLVING ALCOHOL This section presents data on alcohol-involved accidents, as compiled and reported by the California Highway Patrol, as well as accident data which have been crosstabulated with Department of Justice DUI arrest data. Only accidents involving injury or fatality are assessed, due to incomplete reporting of property-damage-only (PDO) accidents. 3 Drivers identified as being under the influence of drugs other than alcohol are also included in the "alcohol-involved accident" category, but typically comprise less than 1% of the total (e.g., only 3 cases for 1994 data). This section includes the following tables: Table 19: Fatal/Injury Accidents of 1998 DUI Arrestees by Race/Ethnicity and Sobriety Code. This table shows the law enforcement officer s determination of sobriety for accident-involved 1998 DUI arrestees, by race/ethnicity. Table 20: Fatal/Injury Accidents of 1998 DUI Arrestees by Race/Ethnicity and Type of Arrest. This table portrays the fatal/injury accident involvement of DUI arrestees, by race/ethnicity and type of arrest (felony, juvenile, or misdemeanor). Table 21: Fatal/Injury Accidents of 1998 DUI Arrestees by Adjudication Status and Sobriety Code. This table crosstabulates accident sobriety codes (from law enforcement accident reports) with the court disposition of the 1998 DUI arrests associated with those accidents. Table 22: Fatal/Injury Accidents of 1998 DUI Arrestees by Adjudication Status and Type of Arrest. This table displays the adjudication status of fatal and injury accidentinvolved 1998 DUI arrestees, by type of arrest. Table 23: 1998 Accident-Involved DUI Arrestees With No Record of Conviction, by County and Type of Arrest. This table shows the number of accident-involved 1998 DUI arrestees without a corresponding recorded conviction, by type of DUI arrest, by county. Tables 24a-24b: 1998 Alcohol-Involved Fatal/Injury Accidents by Age and Sex (Total and Not Arrested). These two tables show the number of 1998 alcohol-involved fatal and injury accidents by age and sex, both total (24a) and those of subjects who were not arrested in conjunction with the accident (24b). 3 Among 1998 DUI arrests, 24,299 were associated with a reported traffic accident, with 11,065 involving an injury or fatality, and 13,234 being PDO. 50

Tables 25a-25b: Sobriety Level by Prior DUI Convictions of 1998 Alcohol-Involved Fatal/Injury Accidents (Total and Not Arrested). These two tables show the number of 1998 alcohol-involved fatal and injury accidents by sobriety level and prior conviction status, both total (25a) and those of subjects who were not arrested in conjunction with the accident (25b). Tables 26a-26b: 1998 Alcohol-Involved Fatal/Injury Accidents by Prior DUI Convictions (Total and Not Arrested). These two tables show the number of 1998 alcohol-involved fatal and injury accidents by number of prior convictions, both total (26a) and for subjects who were not arrested in conjunction with the accident (26b). Table 27: 1-, 3-, and 7-Year Total, Fatal/Injury, and Alcohol-Related Accident Means by Offender Status. This table shows the average number of total, fatal/injury, and alcohol-related accidents for 1998, 1996, and 1989 DUI arrestees for time periods of respectively, 1, 3, and 7 years subsequent to their arrests by offender status (number of prior offenses). Figure 12 (below) shows the annual percentages of traffic injuries and fatalities that were alcohol-involved from 1989 to 1999. The numerical data for this graph are shown on the DUI summary statistics sheet at the beginning of this report. PERCENTAGE OF TOTAL INJURIES AND FATALITIES 60 50 40 30 20 10 0 Fatalities Injuries 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 Figure 12. Percentage of total injuries and total fatalities that were alcoholinvolved, 1989-1999. 51

Based on these data, the following statements can be made:! The number of alcohol-involved traffic fatalities increased by 9.1% in 1999, the first increase in over a decade. The proportion of traffic fatalities which are alcoholinvolved increased (from 31% to 32.8%) for the second year in a row after over a decade of decreases.! The proportion of traffic accident injuries that are alcohol-involved continued to decline in 1999, as it has each year since 1987. The number of alcohol-involved injuries dropped 3.7% during 1999 and 53.3% from 1989 to 1999.! 12.8% of all 1998 DUI arrests were associated with a reported traffic accident, compared to 12.3% in 1997, 12.6% in 1996, 12.4% in 1995, 13.2% in 1994, 13.1% in 1993, and 11.1% in 1992 and 1991. 45.5% of these accidents involved an injury or fatality.! In almost a quarter (23.0%) of cases where a DUI offender was arrested in connection with a reported traffic accident, there is no record of any corresponding conviction. In 90.4% of these nonconvicted cases, the accident report indicated that the drivers had been drinking and that their ability was impaired.! Of all 1998 accident-involved DUI arrestees with no record of conviction, 24.8% had been arrested for felony DUI.! 5.8% (11,065) of 1998 DUI arrests were associated with a fatal or injury accident. Of these fatal/injury accidents, only 30.3% (3,358) led to an arrest for felony DUI, and only 11.0% (1,221) led to a conviction of felony DUI. 77% of DUI arrests stemming from a fatal/injury accident resulted in a reported conviction.! The fatal/injury and total accident risk of DUI offenders generally decreases with the number of prior DUI convictions for periods up to seven years after arrest, while, conversely, the risk of involvement in an alcohol-related accident generally increases with number of priors over the same time periods. This is not surprising because as the number of prior DUIs increases, the time period of the suspension/revocation lengthens, and prior research has demonstrated that suspension/revocation has a larger impact on reducing non-dui accidents than 52

DUI accidents. In addition, drivers with multiple DUI offenses are more likely to have serious drinking problems.! Non-arrested drivers in alcohol-involved fatal/injury accidents in 1998 were less likely to have a prior conviction for DUI or alcohol-related reckless driving, and had lower estimated BAC levels than did drivers who were arrested in conjunction with the accident.! Almost three-quarters (74.3%) of drivers in alcohol-involved fatal accidents had no prior DUI or reckless driving conviction. 53

DATA SOURCES AND LIMITATIONS DUI Arrest Data: Arrest data are reported to the Department of Justice (DOJ), Law Enforcement Information Center, by individual law enforcement agencies throughout the state. As such, these data are subject to reporting errors such as incorrect names, birthdates or arrest dates. Nonreporting of arrest data due to error or omission can also occur; for example, in 1995 the Oakland Police Department reported no DUI arrests, after reporting 960 such arrests in 1994. In addition, when data are entered into DOJ's Monthly Arrest and Citation Register (MACR) system, only the highest-order offense is included. Therefore, in cases where a DUI arrest is made in conjunction with, for example, an auto theft arrest, that DUI arrest will not be included in the database. This results in a slight but systematic underreporting of the number of DUI arrests annually. DUI Conviction Data: Abstracts of conviction for DUI and other traffic-related offenses are reported to the DMV by courts throughout the state. As abstracts are received (either hard copy, magnetic tape or through direct electronic access from the courts) they are entered onto the DMV driver record database. Abstracts without an identifying driver license number are run through the automated name index (ANI) system in order to match the abstract with an existing driver record; in cases where no such match can be made, an "X"-numbered record is created to store the abstract. The total number of DUI abstracts of conviction received by DMV from the courts is tallied monthly and annually. Since this workload total includes abstracts which amend, correct or dismiss prior abstracts of conviction, it tends to overestimate the actual number of convictions which have occurred. Conviction data are also subject to reporting and nonreporting errors similar to those for DUI arrests. For example, the 1993 Annual Report of the California DUI Management Information System documented the fact that thousands of DUI convictions appearing in court records do not appear on the DMV driver record database. Alcohol-Involved Accident Data: Accident data are reported to the California Highway Patrol (CHP) by local law enforcement agencies and district offices of the CHP. As such, these data are subject to reporting and nonreporting errors similar to those occurring in both DUI arrest and conviction data. While most local law enforcement agencies will investigate and file reports on accidents involving injury or death, the investigation and reporting of 61

property-damage-only accidents varies widely by local jurisdiction. Data are entered onto CHP's Statewide Integrated Traffic Records System (SWITRS) and published in annual reports. 62

HISTORY OF MAJOR DUI LAWS IN CALIFORNIA SINCE 1975 AB 1650 (Assembly Transportation Committee), effective 1/1/2000, is a committee bill intended to deal with transportation issues more efficiently by clarifying and making technical changes. This bill authorizes the DMV to impose a driver license suspension on those convicted of DUI in a water vessel involving injury; this remedies an oversight in existing law which provides for sanctions against drivers convicted of DUI in a water vessel without injury than for those with injury. AB 762 (Torlakson), effective 7/1/99, extends the suspension period for a second-dui offender from 18 months to two years, but allows the second offender to serve 12 months of the license suspension period, followed by a restricted license with continued enrollment in a treatment program and installation of an ignition interlock device; requires persons convicted of driving with a suspended or revoked license, where that suspension or revocation was based on prior DUI convictions, to install the ignition interlock device for a period not to exceed 3 years or until the driving privilege is reinstated, and requires DMV to study and report on the effectiveness of these devices. Judges are also encouraged to order installation of an ignition interlock device for first-time DUI offenders if there are aggravating factors such as high blood alcohol readings (0.20% or above), chemical test refusal, numerous traffic violations, or injury accidents. SB 24 (Committee on Public Safety), effective 7/1/99, cleans up AB 762, AB 1916, and SB 1186. This law requires the DMV to revoke for one year the driving privilege of any ignition interlock device-restricted driver who is convicted of driving a vehicle not equipped with an ignition interlock device (IID) under authority section 23247(g); requires the department to suspend or revoke the driving privilege of any IIDrestricted driver [under section 23246(g)] if notified by an installation facility that the driver attempted to bypass, tamper with or remove the device, or has three or more times failed to comply with calibration or servicing requirements of the device; amends certain sections to specify that completion of a program equals enrollment, participation, and completion subsequent to the date of the current violation. SB 1186 (Committee on Public Safety), effective 7/1/99, reorganizes specified provisions relating to DUI-related statutes by amending, repealing, and/or renumbering the DUI-related sections without making substantive changes to the statutes. 63

SB 1176 (Johnson), effective 1/1/99, requires that, upon a conviction of an alcoholrelated reckless driving charge, the courts order enrollment in an alcohol and drug education program as a condition of probation. This bill also requires an evaluation by the DMV of the effectiveness of the program and a discussion of the findings in its annual report to the Legislature. SB 1890 (Hurtt), effective 1/1/99, deletes the choice of the urine test from the options for chemical tests relating to operating a vehicle under the influence of alcohol, unless both the blood and breath tests are unavailable or where there is a condition that warrants the use of the urine test. AB 1916 (Torlakson), effective 1/1/99, provides that the court shall, as a condition of probation, refer a first offender whose BAC level is less than 0.20%, by weight, to participate for at least three months (minimum 30 hours) or longer to a licensed education/counseling program; if the BAC level is equal to 0.20% or more, by weight, or the person refused to take a chemical test, the court shall order the person to participate for at least six months or longer in a program consisting of 45 hours of education/counseling activities; requires the DMV to submit an annual report to the Legislature on the efficacy of the increased drug and alcohol intervention programs; requires repeat offenders who have twice failed the programs to participate in a county alcohol and drug problem assessment program, and requires each county, beginning 1/1/2000, to prepare, or contract to be prepared, an alcohol and drug assessment report on each person ordered by the court to participate in an alcohol and drug assessment program. AB 130 (Battin), effective 1/1/98, requires that any person guilty of a felony or misdemeanor DUI within 10 years of a prior felony offense be designated as a habitual traffic offender for a three-year period and have their driver license revoked for four years. SB 1177 (Johnson), effective 1/1/98, requires that anyone convicted of a second or subsequent DUI within seven years of a separate DUI, alcohol-related reckless driving, or DUI with bodily injury violation, is ordered to enroll in, participate and complete a DUI treatment program, subject to the latest violation, as a condition of probation. The person is not to be given credit for any treatment program activities prior to the date of the current violation. AB 1985 (Speier), effective 1/1/97, cited as Courtney s Law ; provides that a person convicted of gross vehicular manslaughter while intoxicated and who has one or more prior convictions of vehicular manslaughter or multiple prior DUI convictions shall be punished by imprisonment in the state prison for a term of 15 years to life. Also, any person fleeing the scene of a crime after committing specified vehicle 64

offenses which resulted in death, serious injury, or great bodily injury is subject to an additional five-year prison enhancement. SB 1579 (Leonard), effective 1/1/97, permits DMV to suspend a driver license on a first FTA for DUI, and establishes an enhanced audit and tracking system to compare DUI arrests with subsequent actions. SB 833 (Kopp), effective 1/1/96, permits peace officers to seize and cause the removal of a vehicle, without arresting the driver, when the vehicle was being operated by a person whose driving privilege was suspended or revoked or who had never been issued a license; requires an impounding agency to send a notice by certified, return receipt requested mail, to the legal owner of a vehicle that is impounded, and specifies under what conditions an impounded vehicle may be released to the legal owner. AB 321 (Connolly), effective 1/1/95, allows juveniles cited for driving under the influence, with a blood alcohol content (BAC) of 0.05% or more, by weight (Section 23140), to be charged with vehicular manslaughter (PC 192) or gross vehicular manslaughter (PC 191.5) if they violate these vehicular manslaughter laws. SB 1295 (Lockyer), effective 1/1/95, requires every person convicted of a first DUI offense to submit proof of completion of a treatment program within a time period set by the department; requires the department to suspend the driving privilege for noncompliance, prohibits reinstatement until proof of completion is received by the department; enhances the required administrative driving privilege revocation for a minor who refuses to take or fails to complete a preliminary alcohol screening (PAS) test, to two years revocation for the second offense in seven years and three years revocation for the third and subsequent offenses; applies the VC section 23140 to drivers under age 21 (previously under age 18), making it unlawful to drive with a 0.05% BAC level or greater. SB 1758 (Kopp), effective 1/1/95, permits a noncommercial driver, 21 years of age or older, who was arrested for a first Administrative Per Se DUI offense, who took a chemical test, and enrolled in an alcohol treatment program, to also obtain a restricted driver license, valid for driving to and from and during the course of that person s employment, after serving 30 days of the suspension period. The total time period for suspension/restriction shall be six months, rather than four months. Suspended/revoked and unlicensed drivers who drive are subject to having their vehicles towed and impounded for 30 days. If the driver is the registered owner of the vehicle and has a prior conviction for driving while unlicensed or suspended/revoked, the vehicle is subject to forfeiture to local authorities. 65

AB 2639 (Friedman), effective 9/30/94, repeals the statutes which authorized discretionary ignition interlock device (IID) orders (23235), although part of the repealed statutes were incorporated into the sections establishing mandatory orders (section 23246 et seq.). Previously, the discretionary IID orders applied to all DUI offenders, but now they apply only to first-dui offenders. For third and subsequent offenders, the statutes are amended to clarify that the court must require proof of installation of the device before issuing an order granting a restricted license. Some of the exemptions to the IID orders were revised. SB 126 (Lockyer), effective 1/1/94, amends Vehicle Code section 23161 to provide that if the court orders a 90-day restriction for a first offender, the restriction shall begin on the date of the reinstatement of the person s privilege to drive following the four-month administrative suspension; as part of the sentencing of repeat-dui offenders, 23161 requires an ignition interlock device to remain on the vehicle for one to three years after restoration of the driving privilege; specifies that the person cannot operate a motor vehicle when the driving privilege is suspended or revoked even if the vehicle is equipped with an ignition interlock device; requires second offenders who have been suspended for 18 months to provide proof of financial responsibility and proof of successful completion of an alcohol or drug program in order to reinstate their license privilege, includes violation of 23140 for administrative suspension for minors driving with 0.05% BAC or greater. SB 689 (Kopp), effective 1/1/94, prohibits a person under 21 years of age from driving with a blood alcohol concentration of 0.01% or greater, as measured by a preliminary alcohol screening (PAS) test; violators receive a one-year license suspension. A person under the age of 21 who refuses the PAS test will be suspended for one year. AB 2851 (Friedman), effective 7/1/93, requires anyone convicted of a second DUI within seven years of a prior conviction to install an ignition interlock device on all their vehicles. The device must be maintained for a period of one to three years. Proof of installation must be provided to the court or probation officer within 30 days of conviction. If proof is not provided, the DMV will revoke the license for one year. Exceptions to installing a device are for medical problems, use of vehicle in emergencies, and driving the employer s vehicle during employment. AB 3580 (Farr), effective 7/1/93, changes the effective date of administrative per se suspension from 45 to 30 days after the notice is given. SB 1600 (Bergeson), effective 9/26/92, provides that DMV is required to suspend or revoke the licenses of those who drop out of an alcohol treatment program a second time. 66

AB 37 (Katz), effective 1/1/92, combines elements of the formal and informal review hearing into a single hearing for those who were suspended under the administrative per se laws, and provides that DMV need not stay a suspension or revocation pending review, if the hearing followed suspension or revocation for refusing a chemical test for alcohol or for driving with a BAC of 0.08 % or more. SB 185 (Thompson), effective 1/1/92, amends Section 14602 to authorize the court to order the motor vehicle impounded for up to six months for a first conviction, and up to 12 months for a second or subsequent conviction of any of the following offenses: driving with a suspended or revoked license, violation of 2800.2 or.3 (evading a peace officer in a reckless manner, causing injury or death), within seven years of a violation of 23103, 23152, 23153, or penal codes 191.5 or 192(c). AB 2040 (Farr), effective 9/28/90, repeals previous statutes authorizing the installation of ignition interlock devices in DUI cases. This urgency statute authorizes the installation of such devices in all DUI cases, permits the court to grant subjects revoked for 3 or more DUI-related violations a restricted license after 24 months of the revocation have passed. The restricted license is conditioned on satisfactory completion of 18 months of an alcohol treatment program, submission of proof of financial responsibility, and agreement to have an ignition interlock device installed in their vehicles. Courts are authorized to reduce the minimum DUI fine to allow the person to pay the costs of the device. SB 1150 (Lockyer), effective 7/26/90, provides clean-up legislation for APS; lowers the BAC level from.10 to.08, requires proof of financial responsibility to reinstate from any APS suspension or revocation action, increases sanctions for implied consent refusals (one-year license suspension for no priors or APS actions, two-year license revocation for one prior or APS action, and three-year revocation for two or more prior DUI offenses or APS actions), and authorizes suspension or revocation actions taken under 13353 and 13353.2 CVC to be considered as priors. SB 1623 (Lockyer), effective 7/1/90, establishes authority for a peace officer to serve a notice of suspension or revocation (administrative per se or APS) personally on a person arrested for a DUI offense, to take possession of the driver license for forwarding to the department, and to issue a 45-day temporary operating permit; provides for an administrative review of the order, for an administrative hearing, and for a judicial review of the hearing, and provides for a fee, not to exceed $100, to be assessed upon the return of the driver license. AB 757 (Friedman), effective 1/1/90, requires the DMV to establish and maintain a DUI data and recidivism tracking system to evaluate the efficacy of intervention 67

programs for persons convicted of DUI. Annual reports are to be made to the Legislature. SB 310 (Seymour), effective 1/1/90, authorizes the courts to sell the vehicles of those registered owners who are found in violation of Penal Code 191.5 or 192 (C3), CVC 23152 which occurred within seven years of two or more convictions of 23152 or 23153, or a violation of 23153 which occurred within seven years of one or more convictions of 23152 or 23153 or the cited Penal Code sections. SB 408 (Leonard), effective 1/1/90, modifies AB 7 (Hart) to establish a BAC level of.08% or higher as per se evidence of impaired driving. SB 1119 (Seymour), effective 1/1/90 for vessel provisions and 1/1/92 for commercial driver provisions, prohibits the operation of a commercial vehicle by a person with a BAC of.04% or above; requires a commercial vehicle driver to be ordered out of service for 24 hours if found with a BAC at or above.01%, but less than.04%; establishes separate penalties for refusing to take or complete a chemical test based on the type of vehicle involved. Under this bill, a conviction of operating a vessel while under the influence of alcohol or drugs would also be treated as a DUI prior for driver license sanctions. SB 1344 (Seymour), effective 1/1/90, requires statewide implementation of 12-week (30-hour) first-offender alcohol education and counseling programs, and requires state licensing of such programs. This bill also adds 6 months of monitoring and follow-up to second offender programs, resulting in 18-month programs. It requires that DMV evaluate program effects on recidivism and report the findings to the Legislature. SB 1902 (Davis), effective 1/1/90, prohibits DMV from issuing or renewing a driver license unless the applicant agrees in writing to comply with a blood, breath, or urine test. This bill also designates drivers convicted of a third or subsequent DUI within 7 years as habitual traffic offenders. AB 3134 (Harris), effective 1/1/89, allows the 4th DUI within 7 years to be charged as a felony or misdemeanor. The term of imprisonment to state prison or county jail is not less than 180 days and not more than one year. Allows for second offenders to attend either a one year or 30-month treatment program. AB 3563 (Killea), effective 1/1/89, authorizes the court to order DMV to suspend, revoke, or delay the driving privilege of a minor failing to show proof of completion of a court-ordered alcohol education program when convicted of Section 23140 CVC. 68

SB 1300 (Campbell), effective 1/1/89, amends CVC 13202.5 to allow courts to suspend the license of a person under the age of 21 (changed from age 18) for one year, or delay the driving privilege of those 13 years or older, upon conviction of various alcohol and drug offenses, including open container violations. SB 1964 (Robbins), effective 1/1/89, requires all first-dui offenders to file proof of insurance when applying for a restricted license or for reinstatement of the driving privilege following a period of license suspension. SB 885 (Royce), effective 1/1/88, requires that a person who was granted probation for a second DUI offense must show proof of financial responsibility in order to be eligible for the one-year restricted license. SB 1365 (Seymour), effective 1/1/88, establishes a 30-month alcohol treatment program as an alternative to the 12-month program for third and subsequent DUI offenders, in counties where such a program exists. In these cases, imprisonment in the county jail shall be imposed for at least 30 days, but not more than one year, in lieu of the 120-day minimum jail term. AB 2558 (Duffy), effective 1/1/87, provides that gross vehicular manslaughter while intoxicated is punishable in the state prison for 4, 6, or 10 years. Former Section 192(c3) was deleted and incorporated into 191.5(a). AB 2831 (Killea), effective 1/1/87, makes it unlawful for a minor to drive with a BAC of.05% or more (Section 23140 CVC). A conviction of this violation requires completion of an alcohol education program or alcohol-related community service program. SB 2206 (Watson), effective 1/1/87, authorizes a county to develop and administer an alcohol and drug problem-assessment program, which could include a pre-sentence alcohol and drug problem-assessment report for persons convicted under CVC 23152 or 23153, and referral to treatment program with follow-up tracking. SB 2344 (Lockyer), effective 1/1/87, extends the sentencing period for prior DUIs from five to seven years, and specifies a 3- to 5- year probation term for a DUI conviction. SB 3939 (Farr), effective 1/1/87, authorizes courts to order the installation of ignition interlock devices for repeat offenders in four counties, and establishes a pilot project to evaluate the effectiveness of the devices. 69

SB 925 (Seymour), effective 7/1/86, extends the period of license suspension for secondmisdemeanor offenders from one year to 18 months, and also requires that offenders with three or more DUI convictions show proof of treatment completion in order to have their licenses reinstated. AB 144 (Naylor), effective 9/29/85, requires the court to take into consideration in a DUI case a blood alcohol concentration of 0.20 percent or above, or a refusal to take a chemical test, as special factors in the enhancing of penalties for sentencing or to impose additional terms and conditions of probation. SB 1441 (Petris), effective 1/1/85, requires a 3-year license revocation for persons with two or more DUI or alcohol-related reckless convictions within five years of refusing a chemical test. SB 1522 (Alquist), effective 1/1/85, retains existing law for first offenders, which authorizes courts to impound a vehicle at the registered owner s expense for up to 30 days if the driver was convicted of DUI pursuant to CVC 23152 or 23153. The same time period for impoundment is required for second offenses within five years. For third and subsequent offenses, the vehicle can be impounded at the registered owner s expense for up to 90 days. Exceptions to the required impoundment arise where the interests of justice would best be served by not ordering impoundment. Another limitation is that no vehicle driven by a class 3 or 4 licensee is subject to impoundment if another person has a community property interest in the vehicle, and it is the only vehicle available to the driver s family. AB 624 (Moorhead), effective 1/1/84, requires a one-year license revocation for minors (up to age 18) for a DUI conviction (Sections 23152, 23153 CVC). SB 1601 (Sieroty), effective 7/1/82, modifies AB 541 provisions by requiring that SB 38 participants establish proof of insurance in order to remove the license restriction at the end of six months. In addition, SB 38 participants who dropped out of the program are given two more opportunities to reenroll, instead of receiving an immediate license suspension. Program providers are also required to report dropouts directly to DMV. AB 7 (Hart), effective 1/1/82, makes it a misdemeanor under CVC 23152(b) to drive a vehicle with a blood alcohol concentration (BAC) level of.10% or higher. Drivers with lower BAC levels (.05 -.09%) can be convicted of DUI when sufficient behavioral evidence of impairment is apparent. AB 541 (Moorhead), effective 1/1/82, establishes that under CVC 23152(a), driving under the influence of an alcoholic beverage or drugs or their combined influence is 70

a misdemeanor, while felony charges are filed under CVC 23153, and alcoholrelated reckless charges are filed under CVC 23103.5. A conviction under 23103.5 constitutes a prior for a second offense (but not for third offenses). The penalties imposed are a 90-day license restriction (work- and treatment-related driving only) and referral to an alcohol education program for most first offenders; a 1-year license restriction for second offenders who enroll in an approved 12-month alcohol treatment (SB 38) program. First offenders not placed on probation receive a 6- month license suspension. Second offenders not assigned to an alcohol program are suspended for one year. A minimum jail term of 48 hours is mandatory for all repeat offenders, and a minimum fine of $390 is assessed for all DUI offenses. Offenders with three or more DUI or alcohol-related reckless driving convictions receive a 3-year license revocation along with a jail term and fine, and a small proportion are referred to a 12-month SB 38 program. Enrollment in the program cannot be substituted for license revocation. The period defining prior DUIs changes from seven to five years. Convictions of a DUI offense with bodily injury or fatality, when prosecuted as a felony, continue to result in more severe penalties (such as longer license actions and jail terms) than the misdemeanor offenses. The only change in the 1982 law for felony second offenders is that those participating in the SB 38 program will receive a license suspension for one year and a license restriction for two years. SB 38 (Gregorio), effective 1/1/78, extends the pilot 12-month alcohol treatment program for repeat offenders statewide. SB 330 (Gregorio), effective 1/1/76, permits repeat DUI offenders in four counties to participate in a 12-month pilot alcohol treatment program in lieu of the usual 12- month suspension or 3-year revocation. 71

GLOSSARY ADMINISTRATIVE PER SE (APS) Administrative per se ("on-the-spot") license suspension or revocation occurs immediately pursuant to lawful arrest of a person driving with a blood alcohol concentration (BAC) of 0.08% or more, or one who refuses a chemical test. Upon arrest, the driver's license is immediately confiscated by the law enforcement officer and an order of suspension or revocation served. The driver is issued a temporary license and allowed due process through administrative review. In July 1990, California became the 28th state to implement APS. In January 1994, California enacted a "zero tolerance" statute which requires the administrative suspension of any driver under age 21 with a BAC of 0.01% or greater, or who refuses to be tested. ALCOHOL-INVOLVED ACCIDENT Alcohol-involved accidents are those in which the investigating law enforcement officer indicates on the accident report that the driver "had been drinking (HBD)." Accidents involving drivers who are determined to be under the influence of drugs other than alcohol (typically less than 1% of all accidents) are also included in the alcohol-involved accident category. ALCOHOL-RELATED RECKLESS DRIVING Commonly called a "wet" reckless, alcohol-related reckless driving refers to an arrest/conviction incident which originated as a DUI arrest. DUI arrests involving drugs which are reduced to reckless driving are also referred to as alcohol-involved or "wet" reckless driving. "Wet" reckless convictions count as priors for the purposes of enhanced penalties upon subsequent conviction of DUI. ALPHA Alpha is the investigator's acceptable risk or probability level of making a Type 1 error (generally chosen to be small e.g., 1% or.01, 5% or.05). There is always some risk of a Type 1 error, so alpha cannot be zero. Alpha is also called the significance level, because it is the criterion for claiming statistical significance. 74

BAC Blood alcohol concentration, or BAC, is a measure of the percent, by weight, of alcohol in a person's blood. Statutorily, BAC is based upon grams of alcohol per 100 milliliters of blood or per 210 liters of breath. CONVICTION Conviction of an offense, as used in this report, refers to the receipt by DMV of a court abstract of conviction. In a small proportion of cases, an offender may be convicted of an offense but that conviction is not reported to DMV. Such cases would functionally be treated by DMV as though the offender had not been convicted. Because convictions can be amended, corrected, dismissed or simply not reported at all, the conviction totals reported herein are dynamic and subject to change. COVARIATE A variable used to statistically adjust the results of an analysis for differences (on that variable) existing among subjects prior to the comparison of treatment effects. DUI DUI is an acronym for "driving under the influence" of alcohol and/or drugs, a violation of Sections 23152 or 23153 of the California Vehicle Code. LOGISTIC REGRESSION Logistic regression analysis is a statistical procedure evaluating the linear relationship between various factors and the occurrence or nonoccurrence of an outcome event. In this study, the procedure was used to explain the relationship between the various sanctions and the proportion of DUI offenders who incurred accidents and/or DUI incidents. MAJOR CONVICTION Major convictions include primarily DUI convictions, but also reckless driving and hit-and-run convictions. p p stands for probability. For example, if p <.05, the probability is less than 5 chances in 100 that the difference you found is by chance alone. 75

QUASI-EXPERIMENTAL DESIGNS Quasi-experimental designs refer to analyses where the comparison groups are not equivalent on characteristics other than the treatment conditions because random assignment was not used. Caution should be excercised when interpreting the results because of possible confounding of group bias with treatment effects. Covariates are used to statistically reduce group differences prior to the comparison of treatment effects. SIGNIFICANT (STATISTICALLY) If the result of a statistical test is significant, this means that the difference found is very unlikely by chance alone. How unlikely is determined by alpha. 76

APPENDIX A Assembly Bill No. 757 CHAPTER 450 An act to add Section 1821 to the Vehicle Code. relating to driving offenses. (Approved by Governor September 14, 1989. Filed with Secretary of State September 15, 1989.) LEGISLATIVE COUNSEL'S DIGEST AB 757, Friedman. Driving offenses: intervention programs: evaluation. Under existing law, the Department of Motor Vehicles maintains records of driver's offenses reported by the courts. Including violations of the prohibitions against driving while under the influence of an alcoholic beverage, any drug, or both, driving with an excessive bloodalcohol concentration, or driving while addicted to any drug. This bill would, additionally, require the department to establish and maintain a data and monitoring system, as specified, to evaluate the efficacy of intervention programs for persons convicted of those violations relating to alcohol and drugs, and to report thereon annually to the Legislature. The bill would declare legislative findings. The people of the State of California do enact as follows: SECTION 1. The Legislature finds and declares as follows: (a) Drivers under the influence of drugs or alcohol continue to present a grave danger to the citizens of this state. (b) The Legislature has taken stern action to deter this crime and punish its offenders and has provided a range of sanctions available to the courts to use at their discretion. (c) No system exists to monitor and evaluate the efficacy of these measures or to determine the achievement of the Legislature's goals. (d) This lack of accurate and up-to-date comprehensive statistics hampers the ability of the Legislature to make informed and timely policy decisions. (e) It is essential that the Legislature acquire this information, from available resources, as soon as practicable, and that this information be updated and transmitted annually to the Legislature. SEC. 2. Section 1821 is added to the Vehicle Code, to read: 1821: The department shall establish and maintain a data and monitoring system to evaluate the efficacy of intervention programs for persons convicted of violations of Section 23152 or 23153. The system may include a recidivism tracking system. The recidivism tracking system may include, but not be limited to, jail sentencing, license restriction, license suspension. Level I (first offender) and II (multiple offender) alcohol and drug education and treatment program assignment, alcohol and drug education treatment program readmission and dropout rates, adjudicating court, length of jail term, actual jail or alternative sentence served, type of treatment program assigned, actual program compliance status, subsequent 77

accidents related to driving under the influence of alcohol or drugs, and subsequent convictions of violations of Section 23152 or 23153. The department shall submit an annual report of its evaluations to the Legislature.
