Samenvatting
The principal goal of the study was to determine the effect on highway safety of increasing the loaded weight of the truck from 70.000 to 80.000 pounds. It is concluded that (1) the death rate for non-truck occupants in car-truck accidents increases with the weight of the truck and (2) there is no evidence to suggest that this fatality rate "levels off" at a loaded weight of 70.000- 80.000 pounds.
