Accident Reconstruction

In the United States there are 11 million motor vehicle accidents each year, more than 400,000 of which result in death. The most common resulting from automobile accidents are to the head, neck, spinal cord, and low back. The evaluation of such cases often involves a team of experts, including engineers, accident reconstruction experts and biomechanists.

As both an expert witness in biomechanics and certified accident reconstructionist for automobile accident and motorcycle crashes, Dr. John Lloyd is highly qualified to serve as a testifying expert in both roles. This capability is rather unique, since the evaluation of motor vehicle accidents typically requires both skills.

Accident Reconstruction

First the accident reconstructionist evaluates the physical evidence from a crash scene, including skid marks, gouges and other roadway markings, along with crush information from the vehicles involves and their final rest positions. The combined value of this evidence is used to calculate the change in velocity of the subject vehicles.

Biomechanical Analysis

Biomechanists use this information to determine occupant kinematics (motion of the vehicle occupants in response to the impact), kinetics (forces acting on various body parts as a result of the collision) and injury mechanisms. This can include the impact to the head and forces transmitted to the brain, blunt trauma to the low back, and shear forces to the cervical vertebrae. Findings are used to determine whether impact locations and forces provide a causal explanation for claimed injuries. Hence the biomechanist can provide rationale as to whom was at fault for the sustained injuries.

As both an expert witness in biomechanics and certified accident reconstructionist for automobile accident and motorcycle crashes, Dr. John Lloyd is highly valued expert for the evaluation of motor vehicle accidents.
