title: Fatal accident cause and conclusion.
abstract: The Toolmarks Laboratory prepared a report concerning a traffic accident involving the death of a road workman. The driver of the vehicle that hit the workman claimed that the wheels had failed to respond when turning left at a roundabout. A traffic investigator photographed the rack and pinion assembly of the steering system, which was subsequently removed and brought to the Toolmarks Laboratory. The rack and pinion assembly of the steering system was rebuilt, and examination showed that the system functioned properly. Specifically, the front wheels responded correctly to the steering input. Laboratory photographs of the steering system were taken in two different positions, from the same angles as the investigator's photographs at the scene of the accident. It was clear that the steering system had not been assembled properly in the garage.
