Trucks involved in fatal accidents codebook 2009

Abstract

This report provides documentation for UMTRI’s file of Trucks Involved in Fatal Accidents (TIFA), 2009, including distributions of the code values for each variable in the file. The 2009 TIFA file is a census of all medium and heavy trucks involved in a fatal accident in the United States. The TIFA database provides coverage of all medium and heavy trucks recorded in the Fatality Analysis 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.
