MD CDL General Knowledge Exam Simulator 2025

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

The process of becoming a commercial driver in Maryland begins with getting a Commercial Learner’s Permit (CLP), for which you must pass a vision exam, a medical exam, and the 50-question CDL General Knowledge (permit) exam. (There is one exception: You don’t need a medical exam if you will only be engaged in so-called “excepted commerce.”) Additionally, you must pay the necessary fees and provide identification documents when you submit your application.

To turn your dream career into reality, you must understand the various aspects of commercial driving theory. They are described in the official Maryland commercial driver’s license manual (Maryland CDL Handbook 2025), which you should read at least once.

Our Maryland CDL General Knowledge Exam Simulator is designed to make studying more effective. It features a user-friendly interface, so you don’t have to be skilled with computers to integrate this intuitive tool into your study routine. All 50 questions have multiple answer choices, but only one is correct. Please note that you will not receive any feedback if you make a mistake. This simulator accurately simulates the official testing experience, where help is not provided. Instead, it will automatically add the questions you get wrong to your personal Challenge Bank™, which you can visit to improve your knowledge and learn from your mistakes. Our tools are available 24/7 and can be accessed on any compatible device. We keep them up to date, so you’ll always practice with the latest version. To implement the latest updates brought by MVA rules or state law and align with Maryland’s CDL requirements, we have recently updated this simulator for December 2025.

While the path to a CDL can be challenging, your perseverance and dedication will provide you with lifelong skills and a rewarding career. Start today and take the first step toward achieving your professional goals. We’ll help you along the way, but you must put in the time and effort necessary to master commercial driving theory. Use our Maryland CDL General Knowledge Exam Simulator regularly while focusing on making steady progress. Consistency and patience are crucial during your learning phase, where you build the foundation of a successful career.

Took this. I went down to the motor vehicle, didn't miss one.
I took this. I went down to the motor vehicle, didn't miss one on any of my tests, nothing! I walked right through it. It was very simple. Like I said, you know, it gives you a multiple choice. You make your answer—if you get it wrong, on the bottom, it gives you a brief paragraph of what the correct answer is. And it was just so helpful. I mean, that's what I like most about it—it was so easy, and I've recommended it to quite a few of my friends.

Program is definitely.
This program is definitely I hope more people use this program and have the success in passing the CDL B and others that it offers. I am extremely grateful

The best study guide for MVA CDL knowledge tests.
I finished my Tanker endorsement test in less than 7 mins! I finished my Double/Triple in 8 mins and few seconds! I took both tests the same sitting back-2-back. Your learning tools are AWESOME!

Really trust this website.
After hours of searching online for a trusted website where I can complete my hazmat ELDT, I am so glad I found Driving-tests! The website it self looked legitimately, it had many reviews/endorsements that made it seem like a safe website to use, that to me was a big deal, all the other websites that I looked at just seemed very sketchy, and it didn’t feel safe enough for me to put down any personal information. The price seemed very reasonable compared to others as well.
