Vehicles / Crash Reconstruction

Our Vehicles and Crash Reconstruction Group includes Vehicle, Highway, and Human Factors Experts supported by our Tires, Materials, Biomechanical, Illumination, Meteorology, and Fire/Explosion Experts. The input of all these Experts provides the needed information for our Crash Reconstruction Experts to perform complex crash reconstruction analyses and provide demonstrative evidence for courtroom testimony. These Experts have analyzed all types of crashes involving cars, trucks, trailers, buses, recreational vehicles, motorcycles, bicycles, boats, ATV’s, and pedestrians.

Our Vehicle Experts, including Automotive, Mechanical, and Electrical Engineers, have analyzed, designed, manufactured, tested, and operated vehicles and their components. These experts can determine how the vehicle initiated or contributed to the severity of crashes. They are experts in steering, suspension, brakes, electrical/controls/lighting, seats, airbags, seat belts, structural components, fuel systems, “black boxes,” and crashworthiness.

Our Highway Experts include Civil and Structural Engineers with design, construction, and maintenance experience for roads (including slopes, banks, surfaces), bridges, guardrails/barriers/medians, lighting, drainage, and traffic controls. They can determine if the existing highway conditions, including work zone safety, contributed to the initiation or the severity of the crash.

Our Human Factors Experts can evaluate driver fatigue; operator perception and reaction; and actual or possible avoidance maneuvers, to determine their effects on the initiation or severity of the crash.

Our Tire Experts can determine if tires were defective or were damaged in the crash, and also the all-important interaction between the tires and the vehicle. Likewise, our Materials Experts can evaluate damaged vehicle components to determine 1) if they initiated or were a result of the crash and 2) the likely method of failure (e.g. fatigue, corrosion, etc).

Our Biomechanical Experts can evaluate crash forces and render an opinion about crash severity from a biomechanical viewpoint. They can examine the forces acting on the human body and predict how the body will react to those forces. Finally, they can render opinions concerning likely types of injuries that could result from a crash and the specific mechanics of those injuries.

Our Illumination and Meteorology Experts can evaluate how poor lighting and/or weather conditions could have contributed to the crash.

Our Fire/Explosion Investigators can inspect the vehicle and the vehicle site to determine if a fire or explosion caused the crash, or were the results of the crash. Electrical, fuel, and other vehicle components can be inspected and tested to determine if they were the origin and cause of the fire or explosion. They can also evaluate whether the fire or explosion, including carbon monoxide exposure, contributed to the severity of any injuries or deaths.

Finally, we have the trained and certified automotive technicians to inspect, tow, test, disassemble (with photography), and provide secured storage for any vehicle or component.
