U.S. Expands Vehicle Rollover RatingsAug 9, 2004 | AP The National Highway Traffic Safety Administration introduced a new rating system Monday that predicts a vehicle's chance of rolling over in a severe crash and lets consumers compare a vehicle with other similar vehicles.
A five-star rating is the highest, meaning the vehicle's chance of rolling over is 10 percent or less. A two-star rating means a vehicle's chance of rolling over is between 30 and 40 percent. Here are the best and worst performers among 2004 vehicles tested so far.
