View All PlansThe Montana Commercial Driver License Manual (Montana CDL Handbook 2025) is an official resource published by the state’s Motor Vehicle Division (MVD). This handbook describes the various aspects of commercial driving theory in detail, including pre-trip inspections, the air braking system, the licensing process, and safe driving practices. All aspiring commercial drivers must pass the official general knowledge exam, which consists of 50 questions based on this manual. A minimum score of 80% is required to pass, leaving little room for error.
If you want to drive combination vehicles (such as semi-trucks and tractor-trailers) in the Treasure State, you must also pass the official combination vehicles knowledge exam as well as a skills test in a combination vehicle. We’ll help you with the theory part of the licensing process by providing you with access to an intuitive tool designed to boost your learning potential.
Our Free Montana CDL Combination Practice Test includes 25 multiple-choice questions based on Section 6 (Combination Vehicles) of the official Commercial Driver License Manual. All questions include a detailed explanation, which is revealed after you select an answer. Please pay attention to this feedback as it helps you understand the reasoning behind the correct answer. For future reference, we recommend noting this explanation in a notebook or notebook app.
With unlimited attempts and nonstop browser-based access, you can train whenever your schedule allows. Since your knowledge can only be improved gradually, you shouldn’t expect overnight results. Whether it takes you weeks or months, it is crucial to progress at your own pace. To reflect the latest updates brought by MVD rules or state law, we have recently updated this practice test for November 2025. Accuracy is essential when studying commercial driving theory, and you will always practice with the latest version. However, you should also check the official MVD website for the most up-to-date information.
Start your training today and study efficiently with our practice tests. Read the Commercial Driver License Manual multiple times and use it alongside our Free Montana CDL Permit Practice Test. With consistent practice, you’ll ace your theory exams on your first attempt.
