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.
What a Forensic Collision Investigator Does
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 detailed scene review. 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, 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 specialist software 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.
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 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.
