The quality of a vehicle or structure that makes it safe during a crash, helping to protect the occupants from injury.
The engineers focused on improving the crashworthiness of the new car model to enhance passenger safety.
Crashworthiness is formed from "crash" (from Middle English *crashen*, meaning to break or smash) and "worthiness" (from Old English *wyrðe*, meaning worthy or having value). The term describes the ability of a vehicle to protect its occupants during a crash, indicating its value in safety.
Think of a vehicle's ability to be 'worthy' ('worthiness') in a 'crash' — that's why crashworthiness means how well it protects people in an accident.
