FREE Quebec Class 1 Licence Test
Looking for some help to pass your Quebec Class 1 knowledge test? You’ve come to the right place! This is the first of our three Quebec Class 1 Knowledge Practice Tests. We designed them to help you pass the official Class 1 knowledge test – on your first try.To obtain a Class 1 driver’s licence in Quebec, you must meet a series of requirements, starting with your Class 5 driving experience. You must have held a full or probationary Class 5 licence for either 24 or 36 months, depending on how much truck driving experience and training you’ve also had. For details, see the SAAQ website.Next, you must pass a vision exam and submit a medical examination report. Once SAAQ approves the report, you must pass the Class 1 knowledge exam on the theory of operating Class 1 vehicles. Practically all Class 1 vehicles have air brakes, so this would be a good time to also pass the Air Brake knowledge test. In any event, you must pass the Air Brake knowledge test before you take the road test for the Class 1 driver’s licence. These two knowledge tests are based on the official Quebec handbooks, Driver’s Handbook and Driving a Heavy Vehicle.Passing the general knowledge test will enable you to get a Class 1 learner’s licence, which will allow you to practice commercial driving under supervision. You must hold the learner’s licence for either one month or three months, depending on your age, your driving experience, and the amount of truck driving training you’ve had. For details, see the SAAQ website.When you’re ready, you can schedule your two road tests for your Class 1 commercial driver’s licence. The first test is a circle check test, in which you inspect the vehicle’s mechanical components. The second test is a driving test. You must take these tests in a Class 1 vehicle equipped with air brakes.This Quebec SAAQ Class 1 Knowledge Practice Test includes 25 multiple-choice questions on the theory of operating Class 1 vehicles. All practice questions are up to date as of May 2025 and based on the two official handbooks.If you get stuck on a practice question, you can ask our AI Assistant to discuss the question further, give you a hint, or answer your own questions about commercial driving. If you still miss the question, you’ll be shown the correct answer and an explanation before you proceed to the next question.

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).

Your most recent completion of all the tests should be not earlier than 30 days before your exam date.
