MB General Knowledge Test 3
- Perfect for first-time and renewal commercial applicants, and those adding endorsements
- Based on 2024 MB commercial driver's licence manual
- Triple-checked for accuracy
- Updated for December 2024
Driving a commercial vehicle is very different from driving a car. Trucks have different controls and different blind spots. As a commercial vehicle operator, you must travel long distances and face a variety of traffic and weather conditions. You must also be prepared to deal with emergencies such as fires and collisions. Before you can get your commercial driver’s licence in Manitoba, you must study and practice to learn to drive carefully and safely. To get your commercial driver’s licence, you must pass both a written and a practical test. The written test (also known as the truck driver’s licence knowledge exam) has several multiple-choice questions. If you are looking for a practice test before taking the commercial driver’s licence knowledge test, this is the place. This practice test will help you prepare. Please note that this is a sample test and does not replace the official truck driver’s knowledge exam. There are 50 questions with hints and explanations of the correct answer. All questions are based on the official 2024 MB commercial driver’s manual. If you have any questions or comments, please contact us. Good luck!

After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly. - Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the provincial government manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the government publishes them.
