After a vehicle collision, the scene can hold key evidence about what happened. This is especially important where there is injury, major damage or a dispute over responsibility.

The Role of a Forensic Collision Investigator

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 detailed scene review. Photographs are taken before the road is cleaned, reopened or altered, 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 people involved in the crash and those who saw it happen.

Where appropriate, biological 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 insurance claims by setting out the likely cause of the collision. It can also support legal proceedings where there is a dispute over fault, injury or property damage.

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.

Summary

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.
