MT CDL General Knowledge Exam Simulator 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

The Montana Motor Vehicle Division (MVD) handles the application, testing, and issuance of Commercial Driver’s Licenses (CDLs) in the state. You must be 18 to drive commercial vehicles within the state and 21 or older to drive interstate. All applicants must pass the General Knowledge written test before they may obtain a Commercial Learner’s Permit (CLP). This exam evaluates your understanding of commercial driving theory, ensuring you’re prepared to operate a commercial vehicle safely and responsibly. All 50 questions are based on the official Montana commercial driver license manual (Montana CDL Handbook 2025), which is the main reference for students like you.

Traditional study methods are quickly declining in popularity. Spending long hours reading printed text from manuals may cause eye strain, which leads to headaches, blurred vision, and dry eyes. There are plenty of online tools you can choose from, but not all are efficient. Active learning allows you to develop a better understanding of commercial driving theory. Our Montana CDL General Knowledge Exam Simulator will completely change your study routine, providing flexibility and boosting your learning potential. We have designed this tool as a last step before the official CDL permit test. Use it to evaluate your knowledge while you simulate the official testing experience on your device. Just as at the MVD office, you’ll answer 50 multiple-choice questions without assistance.

For your convenience, we have omitted any timer from our simulator. Please avoid rushing and finish each session at your own pace. When you make a mistake, we will automatically add the respective questions to your personal Challenge Bank™. Visit this section to identify areas that need improvement and learn from your mistakes. To increase your chances of passing the official exam on your first attempt, we recommend dedicating several weeks to your learning phase. During this time, you should read the official commercial driver license manual at least once. Train with our other CDL practice tests, and use our Montana CDL General Knowledge Exam Simulator to assess your progress and prepare for your dream career.

3 weeks of studying for me and I passed.
Amazing program. 3 weeks of studying for me and I passed # tests, General, Air Brakes, and Combination.They gave me 3 hours to take them. I finished all 3 in 11 minutes and only 2 wrong answers across all the tests! I highly recommend this program.

This is the best site to assist you….
This is the best site to assist you with learning and passing any driving exam. I studied for combination vehicles for my class A CDL and passed with 100%. I didn't miss any questions. All of the questions in this study guide site matches exactly what is on the state exam. Truly a great resource. I would recommend this site to anyone. Thank you.

Great study system.
Hi: Thank you for developing this study system! I passed the general knowledge, air brakes, and combination vehicles test today the first time around! I would recommend your system to anyone who wants to get their CDL!

Driving-tests.org was the best decision….
Driving-tests.org was the best decision I made to learn and study to pass my CDL exam at the DMV. Through their program I was able to get a passing probability of 98% in less than one month. I studied for most of the endorsements and passed them all on the same day with out any complications. Thank you so much, definitely recommend this site to anyone trying to get their CDL. They could have not made it any easier! 🙏🏽🙌🏽

Second time's a charm!
I tried a couple other websites for some mock tests before taking the test for my hazmat endorsement. I thought I had it whipped. I failed. The DPS examiner handed me a CDL manual and told me to go home and study. I read the chapter for hazmat, but still didn't feel confident with my knowledge. After finding Driving Tests.org, and going through the paces, I finally had the confidence I needed to succeed. This time I pasted with flying colors! 100% Thanks to all at Driving Tests.org! I couldn't have done it without you all! Excellent material! Thanks again and best wishes!
