After a vehicle collision, the scene can hold important clues about what happened. 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 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 detailed scene review. 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 drivers, passengers and witnesses.

Where appropriate, biological evidence may be used to help confirm the occupants of the vehicles 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 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 dispute over fault, injury or property damage.

These investigations can also reveal issues outside the driver’s control, such as faulty street lights, unclear markings or road defects. Identifying these problems can help improve safety for other road users.

Summary

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.
