When vehicles are involved in a crash, the scene can hold important clues 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 recreate the sequence of events.
Reviewing the Collision Scene
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 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, biological 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 accounts given by drivers and witnesses.
If an account does not match the physical evidence, 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 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.
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.
