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 2026), 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.
