NHTSA's New Car Assessment Program rates vehicles to determine crashworthiness 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. NCAP provides consumers with important information in making a new car purchase, and for comparable vehicle models, it provides a direct comparison of the crashworthiness of vehicles. The NHTSA's 5-Star Safety Ratings help consumers make smart decisions about safety when purchasing a vehicle.
