The Large Truck Crash Causation Study (LTCCS) is based on a 3-year data collection project conducted by the Federal Motor Carrier Safety Administration (FMCSA) and the National Highway Traffic Safety Administration (NHTSA) of the U.S. Department of Transportation (DOT). LTCCS is the first-ever national study to attempt to determine the critical events and associated factors that contribute to serious large truck crashes allowing DOT and others to implement effective countermeasures to reduce the occurrence and severity of these crashes. The LTCCS documents 1,070 major crashes with approximately 1,000 variables on each crash obtained through driver, passenger, and witness interviews; crash scene, truck, and driver inspections, police reports; hospital records; and coroners' reports.

NEMSIS is a product of NHTSA’s Office of EMS and in collaboration with the University of Utah is the host of the Technical Assistance Center.
