3 Introduction The Washington State Motor Vehicle laws require that a standard Police Traffic Collision Report form be submitted when an injury or death occurs to any person, or damage to the property of any person to an apparent extent of seven hundred dollars or more. If a collision is not investigated and reported by an officer, the operators of any involved vehicles must submit their own independent traffic collision report as stated in RCW and WAC Collision reports submitted by motor vehicle operators are not used for this report. The Washington State Department of Transportation s (WSDOT) Statewide Travel and Collision Data Office (STCDO) is responsible for collecting, processing, analyzing and disseminating traffic, roadway and collision data pertaining to all public roadways in Washington State. The source used for collision information contained in this summary report originates from collision reports submitted by officers. STCDO staff reviews the submitted collision reports to determine the appropriate location and other relevant collision data. The data is then made available to the STCDO s Collision data mart, where it is analyzed and becomes valuable information, for a variety of customers including: the Regions and Divisions within WSDOT, the Federal Highway Administration (FHWA), other Washington State government agencies, and public or private organizations. This report covers police officer reported collisions on all public roadways in Washington State for the year 211. Tables and charts show frequency and rate of collisions, multi-year trends, collision types, contributing circumstances and other factors. This report reflects a snapshot of available 211 data as of September 4, 212. Contact Information: WSDOT - Collision Data and Analysis Branch (36) WSDOT provides the data in this report with the understanding that it will not be used, contrary to the restrictions in United States Code 23 Section 49, in discovery or as evidence at trial in any action for damages against WSDOT, the State of Washington, or any other jurisdiction involved in the locations mentioned in the data. These entities expressly reserve the right, under Section 49, to object to the use of the data, including any opinions drawn from the data.

4 How to Read This Document The Report is organized into three basic sections an Introduction/Overview section offering a high-level look at Washington (and U.S.) collision numbers; a People, Vehicles, and Collisions section containing most of the detailed collision data; and an Appendix/Glossary to assist the reader with supplementary technical terminology, historical information, and research resources. The data is offered in a variety of ways e.g., collisions sorted by greatest injury severity, county, city, year, hour of day, etc.; injured persons sorted by gender, age, month, traffic-user type (e.g., pedestrians or motorcyclists), city, etc. As a further note, the reader is advised to be aware, throughout the Report, of the distinction between the number of collisions and the number of people injured or who die in the collision; for example, one fatal collision may have three fatalities (i.e., number of deaths). This report presents information in tables, and uses graphs and charts to better display relationships between the data presented. The collision numbers presented here are frequently combined with other kinds of information to put them in a clearer perspective. To assist in this comparative safety analysis, we have several standardization techniques. For example, using rates helps us to control for differences in exposure (a term for capturing the extent to which people are at risk for unwanted events like crashes, injuries, and deaths). This helps in making apples-to-apples comparisons. Presently, the measure for capturing such exposure is vehicle miles traveled (VMT). Over the years, analysts at the Washington State Department of Transportation have continually refined their techniques for estimating VMT on Washington roadways by road class, by county, by metropolitan area, by vehicle type, and by rural-urban classification. To generate accurate VMT figures requires a great deal of time, money, and expertise, and in some cases mileage estimates are not available for many parameters, such as driver age groups. In these cases we use surrogate measures of exposure such as population figures, licensed driver totals, or vehicle registration numbers. The better we understand the nature and causes of collisions, the better we can target safety programs to reduce traffic collisions and injuries. Effective January 1, 29, only the Police Traffic Collision Reports are stored in the collision data repository and used for reporting purposes. Collision reports submitted by motor vehicle operators will be collected and used for public disclosure, but the collision data stemming from these reports will no longer reside within the collision data repository and used for reporting purposes. 211 Washington State Collision Data Summary 4
