  2. Federal Motor Carrier Safety Administration (FMCSA) - Large truck crash causation study (LTCCS) • Evaluated 967 serious truck crashes, 181,000 total crashes • 2001-2003 • Cost of study $18 million • Data collected: - 17 states participated, including Michigan - In Michigan: Genesee, Muskegon, Washtenaw - Up to 1,000 data elements collected in each crash • First nation-wide examination of all pre-crash factors

  3. HIGHLIGHTS OF THE LTCCS • Previously held belief – car driver at fault 70% of the time. • LTCCS finding – car driver at fault 56% of the time. • Driver (both car and truck) factors/error overwhelmingly the cause of truck crashes. • Other factors such as equipment failure (10.1%), engineering (16%) and road condition (13%) seldom a causation factor.

  4. Continued CONCLUSION: More focus must be given to the truck driver. • Speed, fatigue, prescription drug use are significant factors for both car and truck drivers.

  5. TOP FIVE CRASH TYPES • REAR END (23.1%) • Ran off roadway/lane usage (17.8%) • Side swipe/same direction (10.3%) • Rollover (8.9%) • Turning/into path (8%)

  6. TOP FIVE TRUCK RELATED CRITICAL EVENTS • Over the lane/ran off roadway (32.1%) • Loss of control (28.6%) • Other motor vehicle in travel lane (21.7%) • Turning/intersection (10.3%) • Pedestrian/bicycle/other (2.5%)

  7. TOP FIVE TRUCK RELATED CRITICAL REASONS • Driver decision (38%) • Driver recognition (28.4%) • Driver non-performance (11.6%) • Vehicle factor (10.1%) • Driver performance (9.2%)

  8. TOP FIVE TRUCK RELATED ASSOCIATED FACTORS • Brake failure (29.4%) • Traffic flow interruption (28.0%) • Prescription drug use (26.3) • Speed too fast for conditions (22.9%) • Unfamiliar with roadway (21.6%)

  9. CONSTRUCTION ZONE CRASHES • 50 percent increase in work zone fatalities between 1997 and 2004. • 24 percent of fatal crashes in work zones involve a large truck. • Most work zone crashes occur: - on weekdays - during daylight and between noon and 3 p.m.

  10. Continued • Merging process is especially problematic for drivers of large trucks. • Large trucks are over represented in work zone crashes. - Large trucks = 10.3% of all registered vehicles. - Large trucks = 16.1% of total motor vehicle miles traveled. - Large trucks = 24% of all fatal work zone crashes.

  11. MICHIGAN SPECIFIC FACTS • Michigan domiciled carriers are over-represented in Michigan truck crashes – 10-15 percent higher. • Michigan has higher percentage of trucks 10,001 - 26,200 pounds involved in crashes – 15-20 percent higher. • Michigan has higher crash involvement by dump trucks, doubles, auto transporters.

  12. Continued: • Canadian trucks account for only 2 percent of truck crashes in Michigan. • 65 percent of truck crashes occur on two lane roads.

  13. Michigan Truck/Bus Crash Statistics by Calendar Year

  14. CONCLUSION & COUNTER MEASURES • More resources must be directed to commercial vehicle enforcement. • More focus on driver behavior (both car and truck drivers).

  15. RESOURCES State Police Motor Carrier Division can Provide: • Commercial vehicle enforcement awareness training. • Assistance with truck crash investigations - Post crash inspection of vehicle - Evaluation of compliance with hours of service regulations - Evaluation of compliance with State and Federal Motor Carrier Safety Regulations

  16. Continued: • Assistance with hazardous materials incidents. • Special investigation of motor carrier complaints and incidents. • Specialized/advanced CMV training. - Trucks and terrorism - CMV drug interdiction
