What is considered the primary determining factor in the severity of a crash?

The primary determining factor in the severity of a crash is the point of impact. The point of impact refers to the specific area of the vehicles that collide during a crash, which can significantly influence the forces exerted on the occupants and the vehicle itself. When a crash occurs, the location on the vehicle that is impacted is crucial because it determines how much energy is transferred during the collision.

For example, impacts directed toward the front of a vehicle can lead to different outcomes compared to a side-impact collision, both in terms of how the vehicle crumples and how the occupants are protected by safety features such as airbags and crumple zones. Therefore, understanding that the point of impact is central to assessing crash severity helps in evaluating the potential for injury and the effectiveness of safety measures designed to protect passengers.

While vehicle size, location of the crash, and road conditions are all factors that can play a role in crash outcomes, they do not directly dictate the severity of the crash in the same fundamental way that the point of impact does.
