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

Here's an inside look at how we maintain the highest quality in our practice tests.
Content Creation and Verification Process
- Alignment with Official Manuals:
Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information. - Community Feedback Integration:
We leverage feedback from our vast community of users to understand which topics are most frequently tested. This helps us focus on the areas that are most relevant and beneficial for your preparation. - Expert Content Creation:
Our in-house editor, Steven, who has extensive experience in driver education, crafts each question with precision. He conducts a thorough review of each question against the official manuals to ensure accuracy. - Rigorous Review Process:
Once Steven has finalized a set of questions, our team conducts a joint review session. This second level of scrutiny involves content accuracy, proofreading, and fact-checking to eliminate any errors. - User Feedback Mechanism:
After a question goes live on our site, we keep the lines of communication open. Each question features a feedback button, inviting users to report any issues or errors. This continuous feedback loop allows us to address and rectify any concerns promptly. - Responsive Updates:
In line with our commitment to accuracy, we quickly update our practice questions to reflect any changes in the DMV manuals. Additionally, we update the free electronic copy of the state's driver's license manuals on our site, typically within a few days after the DMV publishes them.
Our thorough quality control process ensures that you have access to practice tests that are as accurate and up-to-date as possible. We believe in the power of well-prepared drivers and are dedicated to providing you with the best study tools to help you succeed on your DMV exam.
