View All PlansWelcome to our Montana CDL Class B Practice Test, an intuitive tool designed to boost your learning potential. Whether you want to evaluate your knowledge or learn from your mistakes, this practice test should not be missing from your toolkit. It consists of 50 questions based on the official Montana Commercial Driver License Manual (Montana CDL Handbook 2025). All questions have multiple answer choices, but only one is correct. A minimum score of 80% is required to pass, leaving little room for error.
Do not get discouraged if you make a mistake. The detailed explanation of the correct answer will help you understand why your choice was wrong. This feedback is provided for each question, helping you build knowledge and confidence. Note it in a notebook or notebook app and revisit the material during future practice sessions. Updated for November 2025, this practice test closely reflects the content and format of the official general knowledge exam. However, we have omitted any timer to allow students to practice at their own pace. You should avoid rushing through your learning phase. Dedicate plenty of time to fully understand every part of commercial driving theory, and improve your knowledge one practice session at a time.
You will find the test settings menu in the top-right corner of the page. This menu includes several features and a slider for adjusting the font size. The answer popularity feature, once activated, will display a percentage near each answer choice. This feature lets you see how other students answered and helps you spot questions where misconceptions are common. The answer popularity for a question is revealed only after you make your own choice.
Commercial driving theory cannot be learned overnight. It takes time and effort to build a solid foundation for your dream career. Improve your knowledge gradually and build the confidence to achieve a passing score on your first attempt with the help of our Montana CDL Class B Practice Test.
