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.What a Forensic Collision Investigator DoesA forensic collision investigator looks into vehicle crashes using physical evidence, technical knowledge and witness accounts. Their aim is to explain how the collision took place.Examining the EvidenceThe investigation often begins with a detailed scene review. Photographs are taken before the road is cleaned, reopened or altered, 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 ReconstructionUsing the evidence collected, the investigator can produce a reconstruction of the crash. This may involve computer modelling to test whether the evidence supports the statements made about the incident.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.Why the Investigation Is ImportantA forensic collision report can help with claims made through an insurer by setting out how the crash appears to have happened. It can also support court action where there is a disagreement about responsibility.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 improve safety for other road users.SummaryForensic 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.For more information about more info collision investigation support, visit the more info GBB UK website.
