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 January 2026 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.
