Rollover crashes can have serious consequences. In 2004, 33% of passenger vehicle occupant fatalities were in vehicles that rolled over. This report analyzes data related to passenger vehicle rollovers, including rollover propensity and injury outcomes. The report uses the Fatality Analysis Reporting System and National Automotive Sampling System General Estimates System databases to tabulate data on passenger vehicles and their occupants by a variety of variables and performs logistic analysis of the data. Tabulations focus on years 1994, 2003, and 2004; logistic analysis pools data for years 2000 through 2004. We specifically analyze factors that (a) were associated with vehicle rollovers in single-vehicle crashes of passenger vehicles; and (b) were associated with ejection status and varying degrees of injury severity of occupants of passenger vehicles that rolled over in single-vehicle crashes. Among other things, we also analyze the relationship between various anthropomorphic characteristics, such as the Body Mass Index, and seat belt effectiveness for drivers of passenger vehicles that were in single-vehicle rollovers. This report may be useful to other researchers and may provide a starting point for further analysis of vehicle rollovers and injury outcomes. (Author/publisher)
