5 out of 5 • 1 votes.
Based on 2024 BC commercial driver's license manual Instant feedback
Getting ready to drive a heavy truck (a truck with more than two axes) in British Columbia? You'll need a Class 3 commercial driver's licence. The transportation industry in BC 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 British Columbia Class 3 truck driver's knowledge exam) has several multiple-choice questions. This 50-question Class 3 practice test is a great way to prepare: all of our questions are based on the official 2024 BC 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!
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 BC commercial license applicants
  • Existing commercial license holders adding endorsements
  • BC commercial license renewal applicants
