Are you considering a career in commercial driving? In the Show Me State, you will find plenty of opportunities as a licensed commercial driver. The Class B Commercial Driver’s License (CDL) allows you to operate single-unit vehicles like buses, dump trucks, or box trucks. Before you can get behind the wheel and make deliveries across the state, you must complete the licensing process. As you begin your learning phase, the official Missouri Commercial Driver License Manual (Missouri CDL Handbook 2025) will be your primary study resource. This handbook describes the various aspects of commercial driving theory in detail; we recommend reading its contents multiple times.

Honestly, this website was the best decision I made to.
Honestly, this website was the best decision I made to prepare for my CDL Class A test in Missouri. The questions here are exactly the same as the real exam, same wording, same tricky options, and the same style you’ll face at the DMV. I studied intensively for just one week, going through all the short practice tests, then the Marathon, and finally the Exam Simulator. The Challenge Bank was a game-changer, it gathered every question I got wrong so I could focus on my weak points until I mastered them. Thanks to this site, I walked into the exam fully confident and passed on my first try! If you want a reliable, realistic way to prepare for your CDL written test, I highly recommend this platform.-

They offer the Hazmat training as a video to watch for the ELDT or you can download an audio or a pdf of there "slides". The voice for the audio/video is pleasant. The material is exceedingly dense in information but they compress it in a way that is respectable of your time. The audio at the beginning even specifies that you should feel free to pause etc. You simply click a box to verify that you watched/ read the material. However until you answer multiple choice questions they will not submit your completion. This make sense so you do not simply click a box

About the Missouri CDL

If you can retain information more efficiently through active learning, our Missouri CDL Class B Practice Test is the best choice for you. This intuitive tool closely reflects the content and format of the official general knowledge test. However, we have omitted any timer to let you study at your own pace. Please read every question twice and only select an answer when you’re confident in your choice. Too many students fail on their first attempt simply because they rush. Although the official general knowledge test is timed, preparing ahead of time makes it easier to handle the pressure of a countdown.

State laws and regulations can often change. We regularly update this practice test (most recently for December 2025) to ensure accuracy. However, you should always check the official MO DOR website for the most up-to-date information. You can train with our practice tests anytime, anywhere on earth. They can be accessed directly in a browser on any compatible device. However, you will need a stable internet connection since they don’t work offline.

Employers in many industries are hiring commercial drivers who hold a Class B CDL. Whether you want to support Missouri’s economy or deliver cargo across the United States, you must do so as a licensed commercial driver. Start your learning journey today, study the official commercial driver license manual, and train with our Missouri CDL Class B Practice Test. With consistency and repetition, you’ll build a solid foundation for your dream career.
