This study concentrated on the impact of large trucks on interstate highway safety. The objectives of this study were to investigate the impact of trucks on interstate travel and offer recommendations for improving safety. The procedure involved reviewing the literature, analyzing crash data, discussing the existing situation with the trucking industry, and using the information to develop a list of countermeasures to reduce the number and severity of truck crashes on interstates. The countermeasures were grouped into the general areas of: a) the roadway environment, b) the truck, and c) the driver. The crash data were also analyzed to identify spots and sections on the interstates which had the highest number and rate of truck crashes.
