After a vehicle collision, the scene can hold key evidence about what happened. This is especially important where there is serious damage, injury or disagreement about fault.

What a Forensic Collision Investigator Does

A forensic collision investigator examines road traffic collisions using forensic methods, vehicle knowledge and scene information. 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 cleared or repaired, giving investigators evidence they can return to later.

They may gather broken parts, road marks, impact points and damaged objects. Statements may also be taken from drivers, passengers and witnesses.

Where appropriate, DNA or other forensic evidence may be used to help confirm the occupants of the vehicles at the time of the collision.

Building a Collision Reconstruction

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 where the inconsistency lies.

How the Findings Can Be Used

A forensic collision report can help with insurance claims 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 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 turn scene evidence into a clear account of events. Their work can be useful for claims, legal evidence and improving road safety.
