NHTSA issues first rollover resistance ratings

U.S. Transportation Secretary Rodney E. Slater announced the first rollover resistance ratings for passenger vehicles as the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) finalized a rating program that provides consumers with a measure of a vehicle’s resistance to rolling over in a single vehicle crash.


“By providing consumers with information about the comparative rollover risk of various types of vehicles, they will be better able to choose a safe vehicle for themselves and their family,” Secretary Slater said. “We expect these ratings to drive improved safety, which is President Clinton and Vice President Gore’s highest transportation priority. By providing consumers with additional information, we can motivate manufacturers to respond with safer, more stable vehicles.”


The program gives “star” ratings for rollover resistance as part of the agency’s New Car Assessment Program (NCAP). The highest rating is five stars; the lowest is one star. The ratings released today are for model year 2001 vehicles.


More than 10,000 people die every year in rollover crashes, according to NHTSA. Over 60 percent of the sport utility vehicle (SUV) occupants killed in 1999 died in crashes when their vehicle rolled over, compared to 23 percent for car occupants.


NHTSA Administrator Dr. Sue Bailey stated the importance of these ratings to consumers when shopping for safety. She said that with the rollover resistance ratings, NHTSA is providing consumers with information about one of the deadliest types of crashes.


NHTSA expects motivated manufacturers will respond to consumer demand for safer, more stable vehicles. In 1979 when NCAP ratings for frontal crashes began, just 33 percent of vehicles achieved a four- or five-star rating. By 1997, 85 percent had received four or five stars.


Bailey emphasized that the best consumer advice about rollover is the dramatic effect of seat belts. “Your best chance of surviving a rollover is by buckling up. Eighty percent of the people killed in single vehicle rollovers were unbelted, and we know that belted occupants are about 75 percent less likely to be killed in a rollover crash than unbelted occupants,” Bailey said.


The Rollover Resistance Rating is an estimate of the risk of rolling over if a person has a single vehicle crash, usually when the vehicle runs off the road and is tripped by a curb, ditch or soft soil. It does not predict the likelihood of that crash. The Rollover Resistance Rating is based on “static stability factor,” a measure of a vehicle’s center of gravity and track width to determine how “top-heavy” the vehicle is. The more “top-heavy” the vehicle, the more likely it is to roll over. The lowest-rated vehicles (one star) are at least four times more likely to roll over than the highest-rated vehicles (five stars). Here is the five star rating system:


In a single vehicle crash, a vehicle with a rating of:
























Five Stars –



Has a risk of rollover of less than 10 percent


Four Stars –



Has a risk of rollover between 10 percent and 20 percent


Three Stars –



Has a risk of rollover between 20 percent and 30 percent


Two Stars –



Has a risk of rollover between 30 percent and 40 percent


One Star –



Has a risk of rollover greater than 40 percent
