Insurance Institute for Highway Safety Tests Vehicle Passenger Safety in Rollover and Rear-End Accidents
Rollover crashes constitute 3 percent of passenger vehicle crashes, but about one third of the fatalities. Injuries can occur even if there is minimal roof deformation after a crash. At other times vehicle occupants are unharmed even if there is significant roof deformation. A recent study performed by the Insurance Institute for Highway Safety (IIHS) has demonstrated the inadequacy of the proposed federal rule to increase a vehicle's roof strength from 1.5 times to 2.5 times the weight of a car. The study concludes that 212 of the 668 deaths involved in rollover accidents in 2006 could have been prevented if SUVs had roofs as strong as the best one it tested, more than 3 times the vehicle's weight. Increasing the standard from 1.5 to 2.5 would have saved 108 lives. The results are a stinging rebuke of the automakers' longstanding denial of any connection between roof strength and passenger safety. Auto official
