We have been involved in the forensic evaluation of numerous bicycle, motorcycle and pedestrian accidents, including dynamics and safety issues. Bicycle and motorcycle accidents can be the result of weather conditions, poor bike maintenance, poorly maintained roads and construction, negligence, or ignoring laws and road signs. Collisions between vehicles and pedestrians can result in serious injuries to pedestrians, even at low speeds, as the human body is unprotected in these situations. It is very important to understand the issues surrounding the incident including speed, visibility, impact orientation, and lighting conditions. Our engineers have considerable training and experience in investigating these types of collisions.
