The acronym 'NCAP' stands for New Car Assessment Program, which is a vehicle safety testing program that evaluates the crashworthiness of new cars. It provides consumers with valuable information regarding the safety ratings of vehicles, helping them make informed purchasing decisions. NCAP tests assess various aspects of a vehicle's safety, including its protection in frontal, side, and rollover crashes, as well as the vehicle's features like automatic emergency braking and pedestrian detection systems. The program's findings promote the development of safer vehicles through industry standards and consumer awareness.
