What is the ‘final rest’ position of a vehicle in traffic crash terminology?

The term 'final rest' in traffic crash terminology specifically refers to the position of a vehicle after it has come to a complete stop following a crash. This position is critical in accident reconstruction as it provides investigators with vital information regarding the dynamics of the crash, such as the impact locations, directions of travel, and the forces involved. By understanding where the vehicle ultimately ended up, investigators can piece together the sequence of events that led to the crash and form conclusions about the actions taken by the drivers involved.

In contrast, the other options describe different scenarios. The position before the crash does not represent the effects of the collision, while the location of a parked vehicle would not include any changes caused by the crash sequence. Calculating based on the weight of the vehicles relates more to physics and momentum analysis rather than the positional aspect post-collision. Therefore, the correct understanding centers on the 'final rest' of a vehicle as its position upon coming to a complete stop after the incident.
