2 otorcycle Crashes on the Rise

3 Latest DOT Statistics Motorcycling related injury and fatality have been on the rise for the 11 th year. Motorcycle fatalities make up 14% of all highway h crash fatalities.

4 National Statistics NHTSA Injury and Fatality Statistics Increased 7% from 2006 to ,154 killed in ,000 injured in % increase in motorcycle registration from 2000 to 2005

5 More Riders & More Fatalities According to Insurance Institute for Highway Safety, % increase in motorcycle registration 59.4% increase in motorcyclist fatalities

6 Causes of Fatality & Injury Unlicensed Riders DUI Rider with No Helmet or Bogus Helmet Larger Engine Size Traffic and Road Conditions

7 Motorcycle Helmet Effectiveness According to NHTSA Riders without helmets are 3 times more likely to suffer traumatic brain injuries. Helmets reduce brain injuries by 67% Helmet reduce the likelihood of all fatalities by 37%. 800 more riders could have been saved by helmets in 2007.

8 Focus of Discussion Today How Brain Injuries Occur in Crashes? How Helmets Prevent Injuries? How to Identify Protective Helmets? Why Testing Helmets Matters?

9 Behind the Injury Statistics

10 Going Bare Head?

11 Human Brain

12 Cross Section of Brain Image SKULL DURA

13 Types of Head and Brain Injuries SCALP LACERATIONS SKULL FRACTURES FOCAL BRAIN INJURIES CONTUSION, LACERATION HEMORRHAGE DIFFUSE BRAIN INJURIES CONCUSSION SYNDROMES PENETRATING INJURIES

14 rain Injury Factors in a Crash Sudden Stop and Deceleration Rate Impact Energy Human Natural Tolerance Brain Tissue and Blood Vessel Damage

15 How Helmets Work Space Time

16 Space

17 kull Fracture and Hemorrhage

18 Physics in a Thumb Tack

19 ard Shell = Spread Impact Energy

20 Load Spreading Helmet vs. Surface Bare Head vs. Surface Head vs. Helmet

21 hick and Dense Foam = More Time Sudden stop leads to injury. Foam liner crushing takes time. Reducing deceleration Ending with gentle - longer final stop

22 Protective Helmet = Good Driver

23 Motion

24 Bridging g Vein Rupture

25 Stopping Distance

26 Foam = Braking Time

27 Identify Protective Helmets Snell Label (+ DOT for USA) Snell Label (+ ECE for Europe) Design and Structure Energy Management Capability

28 Old Helmets

29 New Helmets

30 Labels as indirect indicator What DOT Label Means: Manufacturer self-certification

31 ll Snell Helmets Meet DOT Standard NHTSA says Snell implies DOT compliance.

32 Motorcycle Helmet Structure en Face Full Face

33 Bogus Helmet

34 Shell Only Helmet Load Spreading No Increase in Stop time Cannot meet current Motorcycle Helmet Standards Examples Novelty or Bogus Helmets Appeal Light Weight, Close Fitting Downside Much better protection available

35 Bogus vs DOT/Snell Helmets

36 Bogus vs DOT/Snell Helmets

37 No Foam Liner = No Braking Time

38 icycle Helmet & Bogus Helmet

39 Shell & Liner Helmet Load Spreading Longer Stopping Time May Meet Standards Examples Current Motorcycle Helmets Appeal Established Injury Reduction Downside Weight 2 to 4 increase in head diameter

40 Two Helmet Standards (USA) DOT (FMVSS 218) Mandatory minimum impact protection requirement Self-certified Manufacturers arrange reasonable testing Claim DOT certification for their own products Snell M2005 M2010 Voluntary premium impact protection capability Snell certified Snell does pre-market and in-market testing Manufacturers are bound by contract

41 Two Helmet Standards (Eur.) ECE Mandatory minimum impact protection requirement Pre market certified Batch Test for production ECE sanctioned labs Snell M2005 M2010 Voluntary premium impact protection capability Snell certified Snell does pre-market and in-market testing Manufacturers are bound by contract

42 M2010 Energy Management

43 Impact Energy Management Comparison

44 M2010 Summary Helmets must also meet local requirements USA FMVSS 218 (DOT) Europe ECE Differences for Europeans More impact management than ECE Lower G s Gs for sizes 60 cm and up Differences for North Americans Lower G but less impact management than M2005 for Lower G but less impact management than M2005 for sizes 59 cm and down Still more impact management than DOT

45 Snell Program Defined by the License Agreement Grants to the Manufacturer Use of Snell Name and Logo to market appropriately certified helmets Obliges the Manufacturer to Place Snell certification labels l in each unit of certified headgear Report on Snell labeled production and distribution Cooperate with Snell Enforcement Pay fees for labels, certification testing and enforcement testing

46 Effectiveness of Standards Standards = Documents Effectiveness of standards depend on *E Enforceable compliance -Independent certification * Strict and comprehensive policing -Gate-keeping and random sampling * Experience e and competence ce - Expertise and Repeatable testing

51 Certification & Random Tests

52 When, How, Where

53 Finally Snell is the only program that requires pre- market certification testing for gate- keeping and in-market random sample testing for compliance. Snell certified helmets can handle higher impact energy. Snell updates standards to make the best head protection available to all riders.

54 Last Words Riders have no direct indicators of helmet protective capability Riders can look for indirect indicators (e.g.:snell/dot stickers) There are reasonably foreseeable crashes that will exceed a helmet s protective capabilities. In serious crashes riders need all the impact management capability a helmet can offer.
