Driving in Saskatchewan is typically characterized by open landscapes and long, straight roads, except in rural areas. Still, winter driving in the province can be tough, with heavy snowfalls and icy roads. According to an analysis by the RCMP, the two major roads with the most fatalities in Saskatchewan from 2019 to 2024 were Highway 1 (the Trans-Canada Highway) and Highway 16 (the Yellowhead Highway), both major commercial routes. On Highway 1, drivers can encounter ice and blowing snow in winter and high winds powerful enough to push trucks off the road. On Highway 16, drivers must be alert for sharp curves, winter whiteouts, and rough pavement. In such situations, well-performing brakes are critical for safety.
To upgrade your Class 5 licence to a commercial licence, you must pass a vision test and submit a medical report form completed by a physician. You must also pass several knowledge tests: a basic knowledge exam on the rules of the road, a sign exam on the meanings of various traffic signs, and a knowledge exam about the commercial class to which you’re upgrading. Saskatchewan calls this exam the “endorsement exam” for that commercial class. Passing the endorsement exam will allow you to practice driving that class of vehicle under supervision. For Class 1, you must also complete Mandatory Entry-Level Training (MELT). Once you feel ready, you may take the trip inspection and road tests in a vehicle appropriate for the class of commercial licence you’re applying for.
To drive commercial vehicles with air brakes, you must obtain an air brake endorsement on your Class 1, 2, or 3 commercial driver’s licence. The air brake endorsement is mandatory for Class 1 and unavailable for Class 4.
For an air brake endorsement, you must pass the Air Brake knowledge test, based on the official SGI Air Brake Manual. Next, you must also pass the Air Brake practical test, in which you will show an examiner how an air brake system works and how to adjust a manual slack adjuster. You will also explain (but not show) how to adjust an automatic slack adjuster.
This Saskatchewan Air Brake practice test has questions. It is up to date as of August 2025 and based on the official SGI Air Brake Manual. If you’re stumped by a practice question, you can ask the AI Assistant to rephrase it or give you a hint. You can even ask your own questions. If you still miss the question, the AI Assistant will show you the correct answer and an explanation.

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.
