RTA Expert Witness for Accident Reconstruction Reports

Our Road Traffic Collisions Expert Witnesses are frequently instructed to carry out full collision reconstructions based on physical evidence and available data. This includes assessing tyre marks, impact points, vehicle rest positions and road layout to understand how the incident unfolded. Experts may also review weather conditions, visibility and road surface to explain contributing factors. Their findings help clarify how a vehicle was being driven and what happened in the moments before impact. These reports are regularly used in both criminal and civil cases to support or challenge allegations of dangerous or careless driving.

When mechanical failure is a possible cause, our RTA Expert Witnesses assess the vehicle’s condition to determine whether a fault contributed to the collision. This may involve inspecting brakes, steering, suspension or tyres, as well as reviewing service history and previous defects. Their reports help confirm or rule out driver error, poor maintenance or defective parts. In some cases, they provide evidence to support claims of loss of control or help establish whether a defect was known to the driver at the time of the incident. This analysis is essential in criminal prosecutions, insurance disputes and product liability claims.

Our Road Traffic Accident Expert Witnesses assess the decisions and actions of the driver in the lead-up to a collision. They consider key factors such as visibility, response time and line of sight based on scene evidence and the physical layout of the road. Their findings can help establish whether a driver had the opportunity to avoid a hazard, how long they had to react, and whether their behaviour was consistent with the conditions. This type of analysis is especially relevant in cases involving pedestrians, cyclists or vulnerable road users, where precise timing and judgement often play a central role.

Many instructions to our Road Traffic Collisions Expert Witnesses involve the review of CCTV, dashcam or in-vehicle footage. Our experts assess the video material in context with the physical evidence to draw conclusions about distance, positioning and vehicle movement. They evaluate footage frame by frame to determine the timing of key moments and how those compare to witness accounts. This work is often crucial in challenging or supporting allegations of fault, particularly in urban environments or where multiple vehicles are involved.

Our RTA Expert Witnesses are trained to interpret data from black box systems, telematics devices and journey recorders. These sources often contain detailed information on speed, braking, acceleration, and GPS location in the lead-up to a collision. Experts assess whether the data supports or contradicts the version of events provided by the driver or other parties. This analysis is frequently used in cases involving fleet vehicles, emergency services or company cars, where journey logs and driver behaviour may be in question.

Our Road Traffic Collisions Expert Witnesses are often instructed to calculate speed and timing using physical evidence, road layout and vehicle data. They consider braking distances, acceleration, point of impact and final rest position to provide a detailed breakdown of how events unfolded. These calculations are used to assess whether a vehicle was exceeding the speed limit, travelling too fast for the conditions or if the collision could have been avoided. This evidence is frequently central in both criminal proceedings and civil claims involving serious injury or loss of life.

Our Road Traffic Accident Expert Witnesses are regularly instructed in cases involving serious criminal charges such as dangerous driving, causing injury by careless driving or assault with a vehicle. They assess physical damage, vehicle movement and the likely sequence of events. Their reports help determine whether a collision was avoidable and whether the actions of the driver were deliberate, reckless or consistent with a loss of control. This evidence is often key in cases where intent or foreseeability is disputed.

We work with Road Traffic Collisions Expert Witnesses who support civil claims involving injury, loss or alleged fraud. Experts assess whether reported injuries are consistent with vehicle damage and evaluate impact severity using physical evidence and available data. Their input is often used to validate or challenge the account of how an incident occurred. This includes cases involving low-speed collisions, disputed liability or claims involving multiple parties.

Our RTA Expert Witnesses are frequently instructed to provide second opinions on police reports, Crown Prosecution Service reconstructions or findings from another expert. They identify any gaps in the original analysis, reassess the available evidence and offer an independent view. This is often used to test the strength of a prosecution case or support new lines of enquiry. Their input can also highlight where further data may be required to draw reliable conclusions.
