MO CDL General Knowledge Exam Simulator 2025
Turn your dream career into reality and take the first step today. Becoming a commercial driver in Missouri is no easy task, but with preparation and determination, any goal is achievable. Before you can get behind the wheel of a semi-truck or school bus, you must learn commercial driving theory. In The Show-Me State, the Department of Revenue (DOR) publishes the official Missouri commercial driver license manual (Missouri CDL Handbook 2025), which is available for aspiring commercial drivers like you. Please read its contents at least once, and when you’re ready, use our simulator to evaluate your knowledge.
The official CDL General Knowledge (permit) test consists of 50 multiple-choice questions. Your knowledge will be evaluated at a DOR office, where you must obtain a score of at least 80% before the timer runs out. Our Missouri CDL General Knowledge Exam Simulator is designed to closely reflect the content and format of the official exam. All 50 questions have multiple answer choices, but only one is correct. You will not receive any assistance, hints, or detailed explanations for the questions you get wrong. Instead, we will automatically add them to your personal Challenge Bank™, which you can visit after the test ends.
You can enable the voice-over function to increase your focus and improve retention rates. Once activated, an artificial voice will read the questions and answer choices aloud. Since you have nonstop access to this intuitive tool, you can simulate the official testing experience anytime, anywhere in the world. All you need is a compatible device and a stable internet connection. You get unlimited attempts to train with our simulator, so you shouldn’t let a failing score discourage you. Return to our other CDL practice tests and strengthen your knowledge through repetition and consistent practice. Please avoid rushing through your learning phase, as commercial driving is a skill that involves high responsibility. Take as long as you need to master this subject. When you’re ready, use our Missouri CDL General Knowledge Exam Simulator to evaluate your knowledge and see if you’re ready to take the official exam.
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
