After a vehicle collision, the scene can hold important clues about how the incident occurred. This is especially important where there is serious damage, injury or disagreement about fault.

The Role of a Forensic Collision Investigator

A forensic collision investigator examines road traffic collisions using physical evidence, technical knowledge and witness accounts. Their aim is to recreate the sequence of events.

Reviewing the Collision Scene

The investigation often begins with a careful inspection of the location. Photographs are taken before the road is cleared or repaired, 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, DNA or other forensic 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 computer modelling to test whether the evidence supports the accounts given by drivers and witnesses.

If an account does not match the marks, damage or final vehicle positions, the reconstruction can help show where the inconsistency lies.

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 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 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.
