Vehicle crashworthiness refers to a vehicle's ability to protect its occupants during a collision. This includes the design and materials used in the vehicle's structure, which help absorb energy and reduce the impact forces experienced by passengers. Key factors in crashworthiness include the strength of the frame, the effectiveness of safety features like seat belts and airbags, and the overall layout of the vehicle. Testing for crashworthiness is typically conducted through standardized procedures, such as crash tests performed by organizations like the National Highway Traffic Safety Administration (NHTSA). These tests evaluate how well a vehicle performs in various types of crashes, providing valuable information to consumers and manufacturers about safety levels.
