After a vehicle collision, the scene can hold important clues 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 examines road traffic collisions using forensic methods, vehicle knowledge and scene information. Their aim is to explain how the collision took place.

Reviewing the Collision Scene

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 broken parts, road marks, impact points and damaged objects. 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.

Reconstructing the Incident

Using the evidence collected, the investigator can produce a collision reconstruction. 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 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.

Final Point

Forensic collision investigators help turn scene evidence into a clear account of events. Their work can be useful for insurance matters, court cases and road safety reviews.
