When vehicles are involved in a crash, the scene can hold key evidence about how the incident occurred. 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 recreate the sequence of events.
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 a record of the scene.
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 reconstruction of the crash. 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 marks, damage or final vehicle positions, the reconstruction can help show where the inconsistency lies.
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 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 explain how and why a road traffic collision happened. Their work can be useful for claims, legal evidence and improving road safety.
