FREE Alberta Class 1 Licence Test
Want to become a Class 1 (combination vehicle) commercial driver in Alberta? You’ve made an excellent career choice! Drivers of semi-trucks and tractor-trailers should find plenty of employment opportunities in the province. Demand for combination vehicle drivers is especially high in Alberta’s all-important petroleum industry. Demand for combination truck drivers is also high in agriculture and agribusiness, forestry and logging, and freight and logistics (mainly for retail and e-commerce).To apply for a Class 1 commercial driver’s licence in Alberta, you must be at least 18 years of age, hold a Class 5 driver’s licence, submit a medical form completed by a doctor or nurse practitioner, and pass a vision test.Next, you must enroll in Mandatory Entry-Level Training (MELT). The MELT course includes classroom instruction, yard training (pre-trip inspections and basic maneuvers), and behind-the-wheel driving. Complete the classroom portion and pass a written knowledge test on the theory of driving Class 1 vehicles. (Because a Class 1 licence also allows you to drive other classes of commercial vehicles, there may be some questions on the test about those as well.) You must score at least 80% to pass. Passing the test enables you to obtain a Class 1 learner’s licence, which will allow you to practice commercial driving under supervision.For a Class 1 licence, you must be qualified to operate air brakes. To do this, start by completing an approved air brake course and passing an air brake knowledge test. You can take both knowledge tests on the same day.Before you take the road test for a Class 1 licence, you must complete MELT and pass a practical test on air brakes.The Commercial Driver’s Guide and the Air Brake Manual – A Guide for Students are the official references for aspiring commercial drivers in the province. However, if you would like more intensive knowledge training on Class 1 driving than you can get by reading the manuals or taking the courses, we can help!This 25-question Alberta Class 1 Knowledge practice test, the first of five such tests we offer, covers the basics of operating Class 1 vehicles (with air brakes). All practice questions are based on the above two Alberta references. If you get stuck on a question, ask our AI Assistant to give you a hint, rephrase the question, or answer your own questions about commercial driving. If you still miss the question, the AI Assistant will immediately give you the correct answer and an explanation.
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.
