When vehicles are involved in a crash, the scene can hold important clues 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 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 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 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 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 how the crash appears to have happened. 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.
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.
