Motor Vehicle Accident Investigation, Reconstruction and Expert Witness Services

Accident investigation and accident reconstruction are commonly heard terms, but what exactly are they. The following discussion will attempt to shed some light on these processes.

After a motor vehicle accident occurs, particularly one resulting in severe injuries or death, it will usually be investigated and sometimes be reconstructed. There are two primary types of people that perform these duties, the police and independent investigators.

The police will investigate an accident with the intention of determining if any criminal action took place in the accident. The job of the independent investigator is to analyze the causes of the accident so that liability and/or financial responsibility can be determined.

An accident investigation consists of many aspects. However, the investigation usually starts with an inspection of the accident site. At the site, measurements are taken of evidence left by the vehicles such as point of impact, final resting positions, skid marks, scrub marks, and gouge marks.

Vehicle inspections are another typical part of the accident investigation. These inspections will usually include measuring the amount of damage and damage profile of the vehicles. This information will be useful if an accident reconstruction is performed. The mechanical components of the vehicles such as brakes, steering, tires, suspension, lights, etc. may also be inspected and tested to determine if the condition of these components was a causative factor in the accident. The investigation might also include looking at driver qualifications, auditing logbooks, or reviewing other motor carrier compliance related materials. With the accident investigation complete, an accident reconstruction can be performed.

Reconstruction is the process of using physics to determine the speeds of the vehicles, and/or their relative positions at different times during the accident sequence. Information such as pre- and post-impact direction of travel, length of pre-impact skid marks, post-impact distances moved, friction values for the various surfaces the vehicles traveled over, point of impact, impact angles, and weights of the vehicles are all used as inputs into the equations used to reconstruct an accident.
