Commercial drivers must pass a written exam to be licensed to drive in Ontario, Canada. The written exam tests the driver’s knowledge of how to operate a commercial vehicle. This Exam Simulator is just like the official ON Air Brake exam. It contains 25 random questions and will stop as soon as you’ve reached the passing or failing score. You’ll get a new set of questions every time you restart it. The exam simulator is not timed, and you must get at least 80% correct to pass. It is based on the 2025 Ontario commercial driver’s manual.
