AB General Knowledge Test 3 2024

4 out of 5 • 8 votes.
Based on 2024 AB commercial driver's license manual Instant feedback

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 Alberta, 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 20 questions with hints and explanations of the correct answer. All questions are based on the official 2024 AB commercial driver’s manual. If you have any questions or comments, please contact us. Good luck!

Ensuring the accuracy and quality of our practice tests is paramount. Learn more about our rigorous standards in our Commitment to Accuracy article.

Perfect for:

  • First-time AB commercial license applicants
  • Existing commercial license holders adding endorsements
  • AB commercial license renewal applicants
