When vehicles are involved in a crash, the scene can hold key evidence about what happened. This is especially important where there is injury, major damage or a dispute over responsibility.

What a Forensic Collision Investigator Does

A forensic collision investigator examines road traffic collisions using physical evidence, technical knowledge and witness accounts. Their aim is to explain how the collision took place.

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 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 the occupants of the vehicles at the time of the collision.

Building a Collision Reconstruction

Using the evidence collected, the investigator can produce a reconstruction of the crash. This may involve computer modelling 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 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.
