FREE NL Air Brake Practice Test 1
- Based on 2025 NL commercial driver's licence manual
- Updated for August 2025
- Perfect for first-time and renewal commercial applicants, and those adding endorsements
- Triple-checked for accuracy
Welcome to the first of our nine Newfoundland and Labrador Air Brakes Practice Tests! We designed these practice tests to help you pass the official Air Brakes knowledge test on your first try. These practice tests can also help you ace air brake questions on the official Class 1 knowledge test.
All applicants for a commercial driver’s licence must have held a Class 5 driver’s licence for at least one year and submitted a routine medical form. Then you must pass a general knowledge test on the theory of commercial driving. Except for Class 1, if you’ll be applying for an Air Brake Endorsement, you must also complete an approved Air Brake course and pass a separate Air Brake knowledge test. For Class 1, this endorsement is mandatory. The general knowledge test for Class 1 includes test questions on air brakes, so a separate air brake knowledge test is not required. The air brake test questions are based on the official NL Air Brake Manual.
Passing the general knowledge test will entitle you to a commercial learner’s permit, allowing you to practice commercial driving under supervision.
When you’re ready, you can schedule a road test for your commercial driver’s licence. However, if you’re applying for a Class 1 licence, you must complete Mandatory Entry-Level Training (MELT) before taking the road test. MELT for Class 1 includes training in air brakes. You must take the road test in a vehicle that’s representative of the class of licence you’re applying for. For a Class 1 licence or another class of commercial licence with a planned air brake endorsement, you must take the road test in a vehicle equipped with air brakes.
Unfortunately, neither reading the official Air Brake Manual nor taking a short Air Brake course can ensure you’ll pass the Air Brakes knowledge test on your first try. But our knowledge test preparation program does!
This is the first of our nine Newfoundland and Labrador Air Brakes Practice Tests. It includes multiple-choice questions on air brakes. All questions are up to date as of August 2025 and based on the official Air Brake Manual.
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.

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 province'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.
