In Michigan, you must pass the official general knowledge exam before you can get a Commercial Learner’s Permit (CLP). If you plan to operate vehicles equipped with air brakes, you must also pass the official air brakes knowledge exam. If these requirements seem overwhelming, you should know that many other drivers felt the same way but succeeded through persistence.
Test anxiety is a common issue affecting many aspiring commercial drivers, significantly impacting their performance on exam day. The official Michigan Commercial Driver’s License Manual (Michigan CDL Handbook 2026) describes commercial driving theory in detail, but it doesn’t give you insight into the content and format of the official general knowledge exam.
To ensure you go to the SOS office prepared, we have created the Michigan CDL Class B Practice Test, an intuitive tool that can help you build confidence to achieve a passing score on your first attempt. With unlimited attempts and 24/7 browser-based access, you can train with this practice test anytime, anywhere in the world. Train without the pressure of a countdown and finish each session at your own pace. We have omitted any timer from this practice test, so you can review the material and improve your knowledge one question at a time.
