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.

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 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 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 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 the likely cause of the collision. It can also support legal proceedings 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.

Summary

Forensic collision investigators help explain how and why a road traffic collision happened. Their work can be useful for insurance matters, court cases and road safety reviews.
