FREE Newfoundland and Labrador Class 1 Licence Test
To apply for a Class 1 commercial driver’s licence in Newfoundland and Labrador (NL), you must have held a full Class 5 driver’s licence for at least one year, be at least 19 years of age (a year older than in some other provinces), pass a vision test, and submit a medical examination report.After you submit the medical report, you must pass an official knowledge test on the theory of driving Class 1 vehicles. The passing score is 80%. Because nearly all Class 1 vehicles in NL have air brakes, you must also obtain an Air Brake endorsement. To do this, complete an approved Air Brake course and pass the official Air Brake knowledge test and practical test. The Class 1 knowledge test may also include some questions on air brake systems, so studying air brakes may help you pass both knowledge tests.Once you pass the Class 1 knowledge test, you may obtain a Class 1 learner’s licence, which will allow you to practice commercial driving under supervision.In NL, before you may book your road test for a Class 1 driver’s licence, you must also complete Mandatory Entry-Level Training (MELT). The MELT course consists of 112.5 hours of classroom training and hands-on training in operating large semi-trucks, including their air brakes. Because MELT includes inspecting and operating a truck with air brakes, you should obtain the Air Brakes endorsement before starting MELT. (Some MELT course providers may require you to have the Air Brakes endorsement before enrolling in their course.)Once you’ve completed MELT, you may take the road test for a commercial driver’s licence.Digital Government and Service NL has not published a general commercial driver’s license manual, although it has published an official Air Brake Manual. The final chapter of the NL Driver’s Handbook has some information about general commercial driving. If you would like more intensive knowledge training in Class 1 driving than this, we can help!This Newfoundland and Labrador Class 1 Knowledge practice test, the first of three such tests we offer, covers the basics of operating Class 1 vehicles (with air brakes). If you get stuck on a question, ask our AI Assistant to give you a hint, discuss the question in more depth, or answer your own questions about commercial driving. If you still miss the question, the AI Assistant will 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.

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