Crashworthiness is defined as the degree to which a vehicle will protect its occupants from the effects of an accident. In other words, it means how safe a vehicle is. Although it might seem as though a car’s safety features focus on protecting the passengers from the initial collision on the exterior of the vehicle, they actually protect passengers from the second collisions between them and anything inside the vehicle, like the steering wheel or the dashboard.
Those impacts can be the most dangerous of any accident. So when a vehicle is not as safe as it is supposed to be and causes more injuries for the passengers after an accident, the case falls under product liability.
