Another issue related to SUVs is their propensity to rollover during certain steering maneuvers. SUVs are constructed with higher ground clearance for occasional offroad use and, thus, have a higher center of gravity. SUV height, along with other factors, contributes to the average rate of 98 rollover fatalities per million registered vehicles compared with 44 such fatalities per million registered vehicles for all other light vehicle types [3]. Also, in fatal crashes SUVs are twice as likely to rollover as compared with passenger cars, increasing the risk of occupant ejection, fatality, or injury [2].
