How Road Traffic Collisions Are Examined

When two vehicles collide, the people involved cannot simply drive away, especially where there is serious damage or injury. A forensic collision investigator can examine the incident and build a clear account of the collision.

What Does a Forensic Collision Investigator Do?

A forensic collision investigator is someone trained to examine vehicle collisions. Using technical evidence and an understanding of vehicles, they can reconstruct the event.

They do this by reviewing physical and witness evidence, including photographs, witness statements, vehicle damage, debris and nearby structures.

How the Investigation Works

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

They may then speak to witnesses 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 check whether reported events are physically possible. 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 poor road markings, faulty street lighting or road defects. When these issues are found, they may need to be addressed to help improve road safety.

Final Thoughts

Forensic collision investigators help create a clear picture of how a crash happened. Their work can support claims, court cases and safer roads.
