The report provides frequencies by power unit type for all the variables in UMTRI's file of Trucks Involved in Fatal Accidents, 1980-88. The file combines the coverage of the FARS data with the detail of the OMC data. Where no OMC report could be found for a medium or heavy truck listed by FARS, UMTRI conducted a survey, by telephone interview or by mail, to obtain company type information and a detailed physical description of the truck and cargo involved. The data for 1987 and 1988 are based on a sample of cases; cases for 1980-86 include all trucks involved in a fatal accident in the continental United States.
