Getting ready to drive a heavy truck (a truck with more than two axes) in Manitoba? You’ll need a Class 3 commercial driver’s licence. The transportation industry in MB is booming, so now is a great time: heavy truck drivers are in high demand. As a Class 3 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 3 licence, you must pass both a written and a practical test. The written test (also known as the Manitoba Class 3 truck driver’s knowledge exam) has several multiple-choice questions. This 25-question Class 3 practice test is a great way to prepare: all of our questions are based on the official 2025 MB commercial driver’s manual. As you answer the questions, we recommend checking the explanations to gain some further insight into the rule behind it. Good luck and drive safely!
