Based on 2025 YT commercial driver's licence manual
Updated for May 2025
Yukon Class 3 Licence Test 3
Getting ready to drive a heavy truck (a truck with more than two axes) in Yukon? You'll need a Class 3 commercial driver's licence. The transportation industry in YT 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 Yukon Class 3 truck driver's knowledge exam) has several multiple-choice questions. This 22-question Class 3 practice test is a great way to prepare: all of our questions are based on the official 2025 YT 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!
Perfect for first-time and renewal commercial applicants, and those adding endorsements

At Tests.ca, we understand the importance of reliable and accurate practice tests to help you prepare for your driver's knowledge exam. That's why we've developed a meticulous process to create and continually update our practice questions, ensuring they reflect the most current driving laws and regulations.
Here's an inside look at how we maintain the highest quality in our practice tests.
Content Creation and Verification Process
Alignment with Official Driving Handbooks: Every question we develop is based on the most recent version of each province's official driving manual. Our team regularly monitors each province's official website for the latest updates to ensure our practice tests are always aligned with the most current information.
Community Feedback Integration: We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation.
Expert Content Creation: Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy.
Rigorous Review Process: Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors.
User Feedback Mechanism: 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.
Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your driver's knowledge exam.
Our Premium Membership comes with a Pass Guarantee (30-day access and longer). If you successfully complete all the practice tests for your province/territory, we promise you a passing grade on your official written knowledge test or we'll refund your money. Your most recent completion of all the tests should be not earlier than 30 days before your exam date.
