When vehicles are involved in a crash, 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 careful inspection of the location. Photographs are taken before the road is cleaned, reopened or altered, giving investigators evidence they can return to later.

They may gather vehicle fragments, tyre marks, debris and damage evidence. 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 reconstruction of the crash. This may involve computer modelling 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 insurance claims by setting out the likely cause of the collision. 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.
