Free Missouri CDL Permit Practice Test: General Knowledge 2025

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

For commercial driving in the great state of Missouri, major routes include Interstate 44, which begins at Wichita Falls, Texas and connects St. Louis to Springfield, where it terminates; and Interstate 70, which begins at Cove Fort, Utah, connects St. Louis to Kansas City, and finally terminates near Baltimore, Maryland. However, heavy truck congestion and frequent construction or work zones along much of I-70’s length can make driving difficult. U.S. Route 63 starts near Ashland, Wisconsin, connects Columbia and Jefferson City to northern Arkansas, and eventually terminates at Ruston, Louisiana. U.S. Route 60 begins at Brenda, Arizona, proceeds through southern Missouri, and afterward terminates at Virginia Beach, Virginia. Missouri Route 13 links Kansas City with Springfield and passes through the Ozark Plateau. However, as you drive through the Ozarks on some of these roads, you are likely to encounter steep grades and narrow, winding roadways, through which you’ll have to proceed with caution, especially in poor weather.

For you, though, commercial driving on these roads is probably still a bit in the future. It’s likely that you’re here because you want to pass the official knowledge test for a Commercial Learner’s Permit (CLP), a vital credential along the way to obtaining a Commercial Driver’s License (CDL). And because you feel you need a little more help than what you’ve gotten from the official Missouri Commercial Driver License Manual (Missouri CDL Handbook 2025). OK. Let’s do this!

This free Missouri CDL permit practice test, which you’re about to take, is based on the official state manual, just like the official knowledge test. It’s up to date as of October, 2025. And it’s formatted like the official test, too. There are 50 multiple-choice questions on such topics as braking, driving on downgrades, following distance, and vehicle components. Unlike the official knowledge test, each question on this practice test comes with an available hint; use it if you get stuck. Each question also comes with an explanation of the correct answer. Read it carefully if you missed the question so you won’t make the same mistake again next time. What this practice test doesn’t have is a time limit. Take your time, not only to improve your chances of passing the test but also to learn as much as you can from the experience. For example, if you miss a question, you may want to pause and look up the information in the CDL manual before you proceed further with the test.

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

This is the best practice test I have….
This is the best practice test I have seen.It lets you go over the test as many times as you want to even after you get 100% you can keep going over the questions to reassure yourself. I wish I had this when I was studding for my CDL years ago. I would highly recommend this to anyone.

Definitely helpful and I recommend.
Definitely helpful I was a little skeptical at first doing the ELDT hazmat online at first but it's better than doing the in person class also the 50 most common questions print out was good material as well good for future preparation I passed the hazmat test with ease 100%

I read the entire CDL manual for Class B with Air brakes.
I was still worried about the permit test. I started with the example free test and it was great. I decided to pay for the month. I used the full program for 3 days and passed my permit. I missed 1 question on my air brakes and 3 on the general test. I'm going to use again for the driving pre trip test. Highly recommend!

Passed my test on first attempt.
Worked the program to study for my Class A license, and I put almost 20-25 hours into it. Passed on the first try! I only skimmed the book, and learn nearly 99% of everything from the program. I recommend reading the book entirely, but my reading comprehension sucks. The repetition of testing in this program nailed down my understanding for sure. 85-90% of the questions on my test were similar if not the same to the program’s study questions. Highly Recommend
