Mr. Lawrence leads MEA’s Transportation Group in British Columbia. Since joining MEA in 1994, he has conducted technical investigations of over 1500 motor vehicle accidents typically focusing on issues such as speed, impact severity, seat belt use, driver evasion potential, visibility and the interpretation of crash recorder data. Mr. Lawrence has investigated accidents involving passenger cars, truck and vans, heavy-trucks and commercial vehicles, motorcycle, bicycles and pedestrians.

With a background in metal fatigue and fracture mechanics, Mr. Lawrence has also been involved in determining the causes of equipment and product accidents.
