Abstract The objectives of this study were two-fold: (I) to determine the relative accident rates, in accidents per million vehicle miles of travel, of longer combination vehicles (LCV’s) and Non-LCV’s; and (2) to determine, to the extent possible, the relative accident rates for LCV and Non-LCV subgroups, including Tractors-Semitrailers, STAA Doubles, Rocky Mountain Doubles, Turnpike Doubles, and Triples. The study methodology consisted of site visits to commercial motor carriers which operate LCV’s. Mileage and accident data, covering periods of up to five’years, were collected from participating carriers and used to calculate and compare accident rates for LCV and Non-LCV configurations. When practical, comparisons in accident rates among LCV subgroups were also calculated. The differential impacts, if any, which key external factors -a&a, route, terrain, timeof-day, and driver experience - had on LCV and Non-LCV accident outcomes were also assessed. The severity of LCV versus Non-LCV accidents was examined as well. This final report documents the results of these investigations.
