MI CDL General Knowledge Exam Simulator 2025
Welcome to our Michigan CDL General Knowledge Exam Simulator. This intuitive tool can help you prepare for the official CDL General Knowledge (permit) test, which is a necessary step to obtain a commercial driver’s license. You must answer 50 multiple-choice questions and score at least 80% to pass. How well do you know pre-trip inspections, safe driving practices, traffic laws, and emergency procedures? When you’re out there delivering hazardous cargo on Michigan’s roads, even small mistakes can be disastrous. You must be professional at all times, as commercial driving involves a lot of responsibility. As you begin your learning phase, please dedicate at least several weeks to your studies. During this time, you should read the official Michigan commercial driver license handbook (Michigan CDL Handbook 2025) at least once. Use our other CDL practice tests to strengthen your knowledge, and when you’re ready, see if you can pass the official exam by practicing with our simulator.
To simulate the official testing experience, we recommend avoiding any external help. Cheating will not be tolerated at the DOS office, so there’s no point in creating a false sense of security with this simulator. Just like at the official exam, you will not receive any help or insight from our simulator. Instead, the questions you get wrong will be automatically added to your personal Challenge Bank™. Please visit this section to identify areas that need improvement and learn from your mistakes. We understand how difficult it is to master the various aspects of commercial driving theory. That is why we have omitted any timer from our simulator, allowing you to finish each session at your own pace. Read every question twice and only select an answer when you’re confident in your choice. There is no countdown to pressure you, but please keep in mind that the official exam will be timed.
Becoming a safe and responsible commercial driver requires time and effort. We’ll make this goal achievable for you, but you must adopt a smarter approach to studying this subject. Use our Michigan CDL General Knowledge Exam Simulator as the last step before going to the DOS office to take the official exam.
