Truck and Trailer Mechanics or "Commercial Transport Vehicle Mechanics" diagnose, repair and service highway buses and trucks. They work for commercial transport vehicle dealers, garages and service stations. A Commercial Transport Vehicle Mechanic is designated as a Truck and Transport Mechanic under the Inter-provincial Red Seal program.
These mechanics work on the mechanical, electrical and electronic components of vehicles. This includes the fuel, brake, steering and suspension, transmission, emission control and exhaust, and cooling and climate control systems. Some mechanics specialize in one or more of these systems.
Many commercial mechanics - particularly those in fleet maintenance and emergency repair - will work outside in all types of conditions. Other work is carried out within shops.
Commercial Transport Vehicle Mechanics are required to use computerized diagnostic equipment to do preventive maintenance and test vehicle performance. They also work on mechanical and electronic components and do scheduled maintenance, such as oil changes and tune-ups
