After a vehicle collision, the scene can hold important clues about how the incident occurred. This is especially important where there is serious damage, injury or disagreement about fault.

What a Forensic Collision Investigator Does

A forensic collision investigator looks into vehicle crashes using physical evidence, technical knowledge and witness accounts. Their aim is to recreate the sequence of events.

Examining the Evidence

The investigation often begins with a detailed scene review. Photographs are taken before the road is cleaned, reopened or altered, giving investigators a record of the scene.

They may gather vehicle fragments, tyre marks, debris and damage evidence. Statements may also be taken from people involved in the crash and those who saw it happen.

Where appropriate, DNA or other forensic evidence may be used to help confirm who was inside a vehicle at the time of the collision.

Reconstructing the Incident

Using the evidence collected, the investigator can produce a collision reconstruction. This may involve specialist software to test whether the evidence supports the statements made about the incident.

If an account does not match the marks, damage or final vehicle positions, the reconstruction can help show why that version of events may not be accurate.

Why the Investigation Is Important

A forensic collision report can help with claims made through an insurer by setting out how the crash appears to have happened. It can also support legal proceedings where there is a disagreement about responsibility.

These investigations can also reveal road conditions or external factors, such as poor lighting, faded road markings or unsafe road layouts. Identifying these problems can help reduce the chance of further collisions.

Final Point

Forensic collision investigators help explain how and why a road traffic collision happened. Their work can be useful for claims, legal evidence and improving road safety.
