Crashworthiness refers to how well a vehicle can protect its occupants during a collision. It involves the design and engineering of the vehicle's structure, materials, and safety features to absorb energy and minimize injury. Key elements include the crumple zones, which are areas that deform during an impact, and airbags, which provide cushioning for passengers. Testing for crashworthiness often involves simulations and real-world crash tests to evaluate how vehicles perform in various scenarios. Organizations like the National Highway Traffic Safety Administration (NHTSA) conduct these tests and provide safety ratings, helping consumers make informed choices about the vehicles they drive.
