How Vehicle Collisions Are Investigated
After a road traffic collision, the people involved cannot simply drive away, especially if someone has been hurt or property has been badly damaged. A forensic collision investigator can review what happened and help establish the facts.
What Is a Forensic Collision Investigator?
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 scene images, accounts from witnesses, vehicle parts and damage to surrounding property.
How the Investigation Works
The first stage is usually a detailed scene assessment. They take photographs from several angles, as the area will often need to be cleaned and made safe 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 check whether reported events are physically possible. For example, if someone gives an account that does not match the tyre marks, vehicle damage or final resting positions, 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.
Why Collision Investigation Matters
If you are involved in a collision, you may need evidence for your insurer. A forensic collision report can help show how the incident occurred and provide the key details needed to support a claim.
It may also be useful in court. If there has been damage to another vehicle, injury or damage to public property, a forensic collision investigator can provide evidence and explain their findings before a judge or jury.
An investigation can also identify factors outside the driver’s control, 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 explain the facts behind a road traffic collision. Their work can support claims, court cases and safer roads.
