Why is debris often considered common evidence at a crash scene?

Debris at a crash scene is often considered common evidence because it includes various items such as broken parts, dirt, or fluids that were dislodged from vehicles during the impact. This debris can provide crucial insights into the dynamics of the crash, such as the type of vehicles involved and the severity of the collision. For instance, pieces of a bumper or glass fragments can indicate the locations of the vehicles at the moment of impact and help recreate the crash sequence.

Furthermore, analyzing the types of fluids present, like oil or coolant, can reveal important information about the vehicles’ conditions and potential mechanical issues that may have contributed to the crash. This tangible evidence is essential for reconstructing the events leading up to the crash, supporting the understanding of how the collision occurred, and assisting in determining liability.
