I represent families whose loved ones have died in accidents involving semi trucks and other commercial vehicles. When I investigate an accident, I look at a number of variables to determine what impact they had on the accident. The Federal Motor Carrier Safety Administration (FMCSA) is also interested in this information, and supports the work of the University of Michigan Truck Research Institute (UMTRI), which yearly gathers data on fatal accidents involving medium and heavy trucks (weighing more than 10,000 pounds).

The data collected is published in an annual report, Trucks Involved in Fatal Accidents Code Book. The most recent report1 lists variables associated with 3448 fatal accidents. Below are a few of the variables listed in the report:

1. The UMTRI report, Trucks Involved in Fatal Accidents Code Book 2009, is still considered preliminary. It takes years to gather the information and analyze it. This work is supported by the Federal Motor Carrier Safety Administration.
