Ontario Class A Licence Test 2 2024 | ON

5 out of 5 • 3 votes.
Based on 2024 ON commercial driver's license manual Instant feedback
Preparing to drive a semi-trailer truck or a long combination vehicle in Ontario? You'll need a Class A commercial driver's licence. The transportation industry in ON is booming, so now is a great time: truck drivers are in high demand. As a Class A licenced commercial driver, you can work for a trucking company as an employee, or for yourself as an owner-operator. But in order to drive one of the largest vehicles on the road, you must first learn to drive carefully and safely. So before you can get your Class A licence, you must pass both a written and a practical test. The written test (also known as the Ontario truck driver's knowledge exam) has several multiple-choice questions. This 50-question Class A practice test is a great way to prepare as all questions are based on the official 2024 ON commercial driver's manual. As you answer the questions, we recommend checking each question's explanation to gain some further insight into the rule behind it. Good luck and drive safely!
