New Car Assessment Program (NCAP) - 5 Star Safety Ratings
NCAP rates vehicles to determine crash worthiness and rollover safety. The safety ratings are gathered during controlled crash and rollover tests conducted at NHTSA research facilities. Vehicles with a rating of five stars indicate the highest safety rating, whereas a one star indicates the lowest rating.
NHTSA is an organization under the U.S. Department of Transportation (DOT) whose mission is to save lives, prevent injuries and reduce economic costs due to road traffic crashes, through education, research, safety standards and enforcement activity. The New Car Assessment Program provides consumers with important information in making a new car purchase, and for comparable vehicle models it provides a direct comparison of the crashworthyness of vehicles. Information from this program also exists on the required labels on each new vehicle for sale .
