Based on 2025 NT commercial driver's licence manual

FREE Northwest Territories Class 1 Licence Test
To apply for a Class 1 commercial driver’s licence in Northwest Territories (NWT), you must start by being at least 18 years old, holding a full Class 5 driver’s licence, passing a vision test, and submitting a medical examination report filled out by your doctor.After you submit the medical report, you must pass an official knowledge exam on the theory of driving Class 1 vehicles. The Class 1 knowledge test will likely include questions on road signs, commercial driving laws, safe Class 1 operating techniques, air brakes, cargo securement, and pre-trip inspections. The passing score is 80%. All questions are based on the official NWT Basic Driver’s Manual and Professional Operator’s Manual.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.Because nearly all Class 1 vehicles in NT have air brakes, you must also obtain an Air Brake endorsement. To get this endorsement, you must pass the official Air Brake knowledge and practical tests. You won’t need this endorsement as a learner driver, but you must obtain it before you apply for your Class 1 licence.After you’ve read the official manuals, would you like more intensive study to ensure you pass the Class 1 knowledge exam – on your first try? Great! That’s just what we’re here for!This NWT Class 1 Knowledge practice test, the first of three such tests we offer, covers the basics of operating Class 1 vehicles (with air brakes). It consists of 25 multiple-choice questions on air brake systems, braking, coupling, dashboard gauges, pre-trip inspections, traffic signs, and vehicle weight. Like the official knowledge test questions, all practice questions are based on the official manuals.Our AI Assistant stands ready to help you with any practice question. 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 show you the correct answer and an explanation.Once you obtain your Class 1 commercial driver’s licence, you should find that Class 1 drivers are in high demand in NWT. Mining (especially diamond mining) is NWT’s largest private economic sector. Class 1 drivers are in high demand to haul equipment to mines and haul ore and processed minerals from the mines. Class 1 drivers are also in high demand to transport fuel to remote areas, sometimes over ice roads in winter.

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.
