How Road Collision Investigations Are Carried Out

When vehicles are involved in a crash, the scene can hold key evidence about how the incident occurred. 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 looks into vehicle crashes using forensic methods, vehicle knowledge and scene information. 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 vehicle fragments, tyre marks, debris and damage evidence. Statements may also be taken from drivers, passengers and witnesses.

Where appropriate, DNA or other forensic evidence may be used to help confirm who was inside a vehicle 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 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.

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 legal proceedings where there is a dispute over fault, injury or property damage.

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 improve safety for other road users.

Final Point

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.
