At what point should evidence preservation for a collision become a focus?

Preserving evidence at a collision site is critical for understanding the circumstances surrounding the incident, determining fault, and ensuring that any necessary legal proceedings are supported by the available physical evidence. This process should begin before any debris removal takes place.

When debris is removed from the scene, crucial evidence such as skid marks, vehicle positions, or specialized markings indicating point of impact could be lost or altered. This evidence can provide invaluable information about the speed, direction, and impact of the vehicles involved. Therefore, prioritizing evidence preservation before debris is cleared helps to maintain the integrity of the scene for investigation purposes.

The other considerations are important, but they focus on separate aspects of incident management. Injury assessment and victim triage are vital for ensuring the well-being of those involved but do not necessarily protect the physical evidence needed for investigation. While law enforcement arrival initiates formal investigative processes, evidence preservation must already be a focus before they arrive to be effective.
