If you’re planning to drive a small bus/school bus (up to 24 passengers), a taxi, or an ambulance in Saskatchewan, you’ll need a Class 4 commercial driver’s licence. The transportation industry in SK is booming, so now is a great time: Class 4 drivers are in high demand. But in order to drive one or more of those vehicles, you must first learn to drive carefully and safely. So before you can get your Class 4 licence, you must pass both a written and a practical test. The written test (also known as the Saskatchewan Class 4 knowledge exam) has several multiple-choice questions. This 50-question Class 4 practice test is a great way to prepare: all of our questions are based on the official 2025 SK commercial driver’s manual. Good luck and drive safely!
