- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 MI commercial driver's license manual
- Triple-checked for accuracy
- Updated for September 2025
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 2025) 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 DOS 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.
Your personal Challenge Bank™ stores every question you answer incorrectly. Visit this section to learn from your mistakes and practice with the questions you previously got wrong. Pay attention to the detailed explanations provided and note them in a notebook or notebook app for future reference. Premium users can add any questions to their Challenge Bank for personalized practice sessions.
Your progress is saved automatically as long as you’re not in private browsing mode. If you must interrupt a practice session, you can return later and pick up right where you left off. With consistent practice, you can master commercial driving theory within a few weeks. Learn what it takes to become a safe and responsible commercial driver in Michigan, and build the knowledge that will serve you throughout your career.
