How Vehicle Collision Evidence Is Reviewed

After a vehicle collision, the scene can hold key evidence 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 explain how the collision took place.

Examining the Evidence

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 vehicle fragments, tyre marks, debris and damage evidence. 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 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.
