Injury patterns for occupants of small trucks.

A limited number of studies have been completed on the factors contributing to accident-related injuries sustained by occupants of pickup trucks. The increasing number and changing pattern of use of light trucks necessitates the need to critically review this vehicle type with respect to contributing accident factors and associated injuries. This paper investigates the injury mechanisms of occupants of pickup trucks and the surfaces that the occupants contact in roadway accidents. Selection of cases from the Canadian vehicle database was based on the location of the vehicles' most severe impact deformation. The overall occupant injury severity was examined with respect to impact location, impact speed, and magnitude of occupant compartment intrusion. The results of the investigation illustrate the benefits of seat belt restraint use. In addition, identification of frequent injury contact surfaces establishes a reference for improved vehicle design initiatives and standards.
