This fourth MO General Knowledge practice test contains another set of 50 multiple-choice questions based on the official CDL manual. Just like our other practice tests, this one is also designed to prepare you for the General Knowledge portion of your 2025 Commercial Driver’s License exam. There are several answer options, but only one of them is correct. Each question also includes a hint and an explanation. It is recommended that you check each question’s explanation to gain some further insight into the rule being tested. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers. Good luck and drive safely!

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
