This section is required for all commercial licence classes. It encompasses an array of topics that every commercial licence holder must know regardless of their specific licence class. These topics include understanding traffic laws, safe driving practices, basic vehicle operation, handling emergency situations, and more. You'll also learn about the effects of fatigue, distraction and impairment on a driver's ability.

Class A Licence (also known as AZ)

Class A lets you drive a wide range of commercial vehicles, like tractor-trailers or flatbeds. You can haul any size trailer with an A license. The "Z" in "AZ" means you have an air brake endorsement. That means you've proven you know how to use air brakes, which are often used in large, heavy vehicles. Make sure you also complete the "Air Brake Endorsement" section below. The Class A knowledge test covers general trucking knowledge, safety protocols, and large vehicle management, including specifics of handling large trailers.
