The TRL Expert Witness and Investigations Team

With comprehensive coverage of the UK, the TRL Expert Witness  and Investigations Team delivers unrivalled experience in all areas of incident investigation, for public and private sector clients including solicitors, insurers, police and government bodies in both Criminal and Civil proceedings.

Working from offices across the country our team of specialists have a track record in providing a responsive service, mobilising expert resources rapidly to gather evidence. We have many long standing repeat clients in the UK and abroad who trust our high calibre team.

Collision investigation and reconstruction

Investigation of road traffic and other incidents demands the highest levels of thoroughness and technical accuracy. Our accident reconstruction reports are known to provide clear, balanced and reasoned opinion.

Our team are able to provide preliminary independent and impartial advice to assist our clients in determining how to proceed with a case. We can review police and other expert reports and findings to provide an early indication of stance on liability. 

Rapid response scene and vehicle inspections

Evidence deteriorates rapidly at incident scenes due to the weather, traffic flow or essential repair work. The environment in which vehicles are kept after an incident can also affect continuity and quality of evidence. This scene and vehicle data can be crucial in the resolution of serious injury claims as it provides independent factual evidence as to the circumstances of the incident.

On receipt of a new instruction, we aim to collect all available incident evidence within days enabling us to record perishable evidence at the scene and capture short-lived marks on vehicles, such as contact marks from pedestrians. This also provides a greater likelihood of capturing details such as mirror positions on HGVs before vehicles are restored to service

Expertise in every aspect of transport and technology

The Expert Witness and Investigations team sits within the Engineering & Technology division at TRL, which is at the forefront of research into new vehicle technology. This includes carrying out research and providing consultancy advice on cutting-edge new topics such as autonomous vehicles, connected transport and the analysis of on-board electronic vehicle data. Because of TRL’s scale and range of transport expertise, our accident reconstruction team have access to a large range of experts in all aspects of transport research including new technologies, vehicle design, regulations, biomechanics expertise, highways engineering and human factors. We can call on experienced specialists from within our own organisation to contribute niche technical and scientific knowledge where it is needed.
