  • 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


Highlights of the ltccs

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.

  • 50 percent increase in work zone fatalities between 1997 and 2004.

  • 24 percent of fatal crashes in work zones involve a large truck.

    - on weekdays

    - during daylight and between noon and

    3 p.m.


Continued1

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.


Michigan specific facts

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.


Continued2

Continued:

  • Canadian trucks account for only 2 percent of truck crashes in Michigan.

  • 65 percent of truck crashes occur on two lane roads.
