There are no minimum requirements for expert witnesses in Houma car accidents. Someone may have worked for a local auto dealer as a mechanic and, on an issue involving mechanics, their experience over many years may allow expert status. Other experts in car crash cases are on the damages end. Sometimes biomechanical engineers look at the deformity in the vehicles, listen to the testimony of the witnesses as to the speed and weight of the vehicles, and make a determination whether the forces involved caused a particular injury.
