crashworthiness
Collision survival capacity
Crashworthiness is how well a vehicle protects occupants during a collision.
Engineers design for crashworthiness through crumple zones, airbags, and reinforced passenger compartments.
Insurance and safety organizations rate vehicles on crashworthiness: The sedan scored highly in crashworthiness tests.
The concept extends to aircraft and other conveyances where impact survival matters.
