This research sets out to estimate the effects of vehicle incompatibilityon the risk of death or major injury to drivers involved in two-vehicle collisions. Based on data for 2,999,395 drivers, logistic regression was used to model the risk of driver death or major injury (defined has being hospitalized). Our analyses show that pickup trucks, minivans and sport utility vehicles (SUVs) are more aggressive than cars for the driver of the other vehicle and more protective for their own drivers. The effect of the pickups is more pronounced in terms of aggressivity. The point estimates are comparable to those in the Toy and Hammitt study [Toy, E.L., Hammitt, J.K., 2003. Safety impacts of SUVs, minivans, and pickup trucks in two-vehicle crashes. Risk Analysis 23, 641-50], but, in contrast to that study, weare now able to establish that a greater number of these effects are statistically significant with a larger sample size.

Male drivers, older drivers, drivers who are not wearing safety belts, collisions occurring in a higher speed zone and head-oncollisions significantly increase the risk of death. Except for the drivers sex, all of these categories are also associated with an increased risk of death or of being hospitalized after being involved in a two-vehicle collision. For this risk, a significant increase is associated with femaledrivers.
