If a driver is ejected from a vehicle during an accident, what term describes the mechanism of injury associated with the impact against the ground?

Why this is the correct answer

In a traffic accident, injuries can occur through three different mechanisms: (1) DIRECT mechanism: injuries caused by the body physically hitting an external object (the ground, dashboard, steering wheel, windshield, guardrail, etc.). The impact comes from outside the body. (2) INDIRECT mechanism: injuries caused by sudden acceleration or deceleration forces acting inside the body, without external contact. For example, internal organs can tear or shift due to abrupt speed changes. (3) MIXED mechanism: a combination of both direct and indirect injuries occurring together, often seen in rollovers or when an occupant is thrown from the vehicle. In this scenario, a driver ejected from a vehicle hits the ground. Since the ground physically strikes the body from the outside, this is a DIRECT mechanism of injury. The image shows a motorcycle accident where the rider has been thrown off, illustrating a typical ejection scenario.
