TRUCKS INVOLVED IN FATAL ACCIDENTS CODEBOOK 1994 (VERSION MAY 6, 1996)

This report provides one-way frequencies for all the vehicles in UMTRI's file of Trucks Involved in Fatal Accidents, 1994. The TIFA database provides coverage of all medium and heavy trucks recorded in the Fatal Accident Reporting System (FARS) file. TIFA combines vehicle, accident, and occupant records from FARS with information about the physical configuration and operating authority of the truck from the TIFA survey. Some sampling was done in selecting cases for the file. Half the cases where the FARS body type and vehicle trailering variables indicated the vehicle was a straight truck or a tractor were taken. All other FARS cases were taken with certainty.
