Newfoundland and Labrador Class 1 Licence Test 3
Preparing to drive a semi-trailer truck or a long combination vehicle in Newfoundland and Labrador? You'll need a Class 1 commercial driver's licence. The transportation industry in NL is booming, so now is a great time: truck drivers are in high demand. As a Class 1 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 1 licence, you must pass both a written and a practical test. The written test (also known as the Newfoundland and Labrador truck driver's knowledge exam) has several multiple-choice questions. This 28-question Class 1 practice test is a great way to prepare as all questions are based on the official 2025 NL commercial driver's manual. As you answer the questions, we recommend checking each question's explanation to gain some further insight into the rule behind it. Good luck and drive safely!

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.
