How Road Traffic Collisions Are Examined

When two vehicles collide, the people involved cannot simply drive away, especially if someone has been hurt or property has been badly damaged. A forensic collision investigator can examine the incident and help establish the facts.

What Does a Forensic Collision Investigator Do?

A forensic collision investigator is someone trained to examine vehicle collisions. Using forensic methods and vehicle knowledge, they can piece together how the collision happened.

They do this by collecting evidence from the scene, including photographs, witness statements, vehicle damage, debris and nearby structures.

What Happens During the Investigation

Investigators begin by assessing the scene. They take images from different viewpoints, as the area will often need to be cleared and reopened soon afterwards.

They may then take witness statements from drivers, passengers and anyone who saw the collision. Physical evidence is also collected, such as parts of the vehicles, road marks and damage to nearby objects.

Where needed, investigators may also collect DNA evidence to help confirm vehicle occupants at the time of the crash.

The evidence can then be used to create a forensic collision reconstruction. This may be produced using computer software to test witness accounts. For example, if someone gives an account that does not match the physical evidence at the scene, the reconstruction may help show that inconsistency.

Once the investigation is complete, a written report is prepared. This explains the likely sequence of events and the evidence behind it.

The Benefits of Collision Investigation

If you are involved in a collision, you may need evidence for an insurance claim. A forensic collision report can help show who was at fault and provide the key details needed to support a claim.

It may also be useful in court. If there has been a dispute about responsibility or damage, a forensic collision investigator can prepare a report and give evidence before a judge or jury.

An investigation can also identify external causes, such as unclear signs, defective lights or unsafe road conditions. When these issues are found, they may need to be addressed to help improve road safety.

Key Takeaway

Forensic collision investigators help create a clear picture of how a crash happened. Their work can support insurance claims, legal proceedings and road safety improvements.
