The study examined single-vehicle crashes from the National Accident Sampling System (NASS), to suggest how vehicle factors and roadside features interact in generating rollovers. Crashes were identified for a 1000-case sample stratified on vehicle stability factor (half the track width divided by center of gravity height) and wheelbase. Hard copies of the NASS cases were obtained and details of the crash dynamics and roadside features were recorded on a coding form by an experienced accident investigator. The data were then entered into an automated database. Due to the exploratory nature of the study and the small numbers in the subsamples, the data were analyzed in unweighted form. Consequently, the study should be viewed as heuristic: the results cannot be generalized and taken as representative of the national population of cars and light trucks in accidents.
