After a vehicle collision, the scene can hold key evidence 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.

Reviewing the Collision Scene

The investigation often begins with a careful inspection of the location. Photographs are taken before the road is cleared or repaired, giving investigators a record of the scene.

They may gather vehicle fragments, tyre marks, debris and damage evidence. Statements may also be taken from drivers, passengers and witnesses.

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 accounts given by drivers and witnesses.

If an account does not match the physical evidence, the reconstruction can help show where the inconsistency lies.

How the Findings Can Be Used

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 court action where there is a disagreement about responsibility.

These investigations can also reveal issues outside the driver’s control, 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.
