| Summary: | This report provides one-way frequencies for all the vehicles in UMTRI's file of trucks involved in fatal accidents, 1993. 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. For the first time since 1986 no sampling was done on the FARS cases. The 1993 TIFA file is a census of all medium and heavy truck fatal accidents in the United States, including Alaska and Hawaii. Tractors accounted for 66.7% of the power units. Tractors with twin trailers made up only 3.9% of the involvements. Only 21.2% of the accidents occurred on interstate highways. Accidents at night and twilight comprised 33.2% of the total number of cases. In 1993, there were 4,451 medium and heavy trucks involved in fatal accidents in the United States, up 7.9% from 4,125 in 1992. |
