Driving a commercial vehicle is completely different from driving a car. Drivers must know more about their vehicles, and they need to take extra safety precautions. A commercial driver’s licence is required to drive a commercial vehicle of a certain size and weight in Canada. To obtain a commercial driver’s licence in Manitoba, the driver must pass a written knowledge test and a road test. This 673-question Marathon contains all questions from our other MB Air Brake tests. It will cycle through them until you’ve provided a correct answer to each of them. The Air Brake Marathon is based on the 2025 Manitoba commercial driver’s manual. You can also use our regular Air Brake practice tests for MB to prepare for your test. When you’re ready, take the Air Brake Exam Simulator.
