Abstract
Heavy trucks comprise a large proportion of vehicles using the highways. Because of their size and sometimes hazardous cargo, the safe operation of these vehicles is a major public concern. Tractor-trailer-combinations, the largest vehicles on the road, attract particular attention. Most research on the safety of these vehicles deals with their design and with the effects of motor vehicle standards and other regulations. Comparatively few studies, especially in Canada, have addressed how, and to what extent, tractor-trailers contribute to the overall traffic-crash problem. The purpose of this paper is to describe the involvement of tractor-trailers in fatal road accidents over a six-year period (1974 to 1979) in seven Canadian provinces. Data for the study came from the TIRF Motor Vehicle Fatality Database.
