What does secondary contact refer to in a collision?

Secondary contact refers to subsequent collisions that occur after an initial impact. In the context of a collision, this means that after the first impact, there may be additional impacts involving the same vehicle or other vehicles, often as a result of the initial crash dynamics. These follow-up impacts can complicate the understanding of the accident scene and the injuries sustained, as the forces and angles of impact may differ from those of the primary collision.

Understanding secondary contact is crucial for accident reconstruction, as it helps investigators to determine the full sequence of events, assess damage, and evaluate liability. The other options do not accurately define secondary contact; they refer to aspects of the collision or the aftermath but do not specifically address the concept of follow-up impacts after the first collision occurs.
