View All PlansA 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.
