About this test

If you want to drive a truck in Manitoba, you need a commercial truck driver’s licence. With a commercial driver’s licence, you can work for a trucking company as an employee or work for yourself as an owner-operator. The transportation industry in Manitoba is booming, and truck drivers are in high demand. As a driver of one of the largest vehicles on the road, you must study and practice to learn to drive carefully and safely. Before you can get your commercial driver’s licence, you must pass both a written and a practical test. The written test (also known as the Manitoba truck driver’s licence knowledge exam) has several multiple-choice questions. You must get at least an 80% to pass the knowledge exam. The knowledge test for each class of licence typically takes approximately 30 minutes. For the practical test, you will meet with an examiner to demonstrate your knowledge of the operation of a truck. The official Commercial Driver’s Handbooks are great resources, but they lack practice. This 55-question MB General Knowledge practice test is a great way to start as it covers the basics of commercial driving in Manitoba. All questions are based on the official 2024 MB 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!
