How Vehicle Collision Evidence Is Reviewed

When vehicles are involved in a crash, the scene can hold key evidence about what happened. This is especially important where there is injury, major damage or a dispute over responsibility.

The Role of a Forensic Collision Investigator

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 careful inspection of the location. Photographs are taken before the road is cleared or repaired, giving investigators a record of the scene.

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 the occupants of the vehicles 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 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.

How the Findings Can Be Used

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.

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.
