Missouri CDL Class A Practice Test 2025

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

A Commercial Driver’s License (CDL) in Missouri opens up a wide range of job opportunities across both urban and rural areas. From hauling grain to delivering construction materials, the state’s economy relies heavily on skilled commercial drivers. As a Class A CDL holder, you’ll do demanding jobs such as hauling steel coils from factories in St. Louis to fabrication yards across the Midwest. If this is your dream career, you should begin the licensing process as soon as possible.

During the early stages of your learning phase, the official Missouri Commercial Driver License Manual (Missouri CDL Handbook 2025) will be your primary study resource. It is published by the Missouri Department of Revenue (DOR) and has several chapters on the various aspects of commercial driving theory. You should read its contents multiple times, but to fully master this subject, it is highly recommended that you use other efficient tools too.

Our Missouri CDL Class A Practice Test has been designed to help you study commercial driving theory efficiently. This intuitive tool has 94 questions, and you must score 80% or higher to pass. With unlimited attempts, you can practice as often as your schedule allows. Do not let a low score discourage you. It is perfectly normal to make mistakes, and we give you the opportunity to learn from them. A detailed explanation of the correct answer is provided for each question. You should note this feedback in a notebook or notebook app for future reference. “Officer Frank,” our automated assistant, will be present during your training sessions. You can request hints that nudge you in the right direction whenever you get stuck on a difficult question. Additionally, this AI coach can provide real-life examples and further explanations.

Studying commercial driving theory doesn’t have to be a chore. It may take you weeks to fully master this complex subject, but having a strong understanding of pre-trip inspections and safe cargo handling is crucial. Use our Missouri CDL Class A Practice Test to improve your knowledge and ace the official written knowledge test on your first attempt.

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
