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 Newfoundland and Labrador, the driver must pass a written knowledge test and a road test. This 434-question Marathon contains all questions from our other NL 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 Newfoundland and Labrador commercial driver’s manual. You can also use our regular Air Brake practice tests for NL to prepare for your test. When you’re ready, take the Air Brake Exam Simulator.
