Maine CDL Class A Practice Test 2025

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

To become a licensed commercial driver in Maine, you must meet several requirements and complete the licensing process. You may begin driving commercially in the Pine Tree State at 18, but crossing state lines and transporting passengers or hazardous materials aren’t allowed until you’re 21. All applicants must hold a valid driver’s license, provide identification documents, and pay the licensing fees. The DOT Medical Exam ensures you meet the physical standards necessary for this profession. This exam is required by the Federal Motor Carrier Safety Administration (FMCSA) and must be done by a certified medical examiner listed on the National Registry.

The official general knowledge exam has 50 multiple-choice questions. You must answer them before the timer runs out and score 80% or higher to pass. After passing this test, you will receive a Commercial Learner’s Permit (CLP), which you must hold for at least 14 days. FMCSA mandates Entry-Level Driver Training (ELDT) for all aspiring commercial drivers in the United States. You must complete this training before you can schedule and take a skills test.

If you are interested in obtaining a Class A CDL, you must pass two more knowledge tests. The official combination vehicles written exam will evaluate your understanding of the safe operation of combination commercial vehicles. Since most semi-trucks are equipped with air brakes, you must also pass the official air brakes knowledge test to be able to legally drive them.

Our Maine CDL Class A Practice Test can help you master commercial driving theory efficiently. It consists of 93 questions based on the official Maine Commercial Driver’s Manual (Maine CDL Handbook 2025). Unlike the official exam, this practice test is not timed. Please avoid rushing and finish each session at your own pace. To reflect the latest updates brought by DMV rules or state law, we have recently updated this practice test for December 2025.

Start today and train with this practice test for several weeks. Commercial driving theory takes time to master, so you shouldn’t expect overnight results. With unlimited attempts and nonstop access, our Maine CDL Class A Practice Test can be a game-changer when used regularly.

CDL manual for school bus driver.
I googled CDL Manual as I am interested in becoming a school bus driver. I like how the website took me straight to the Manuel for my state to print off. For me being a beginner, some helpful tips on exactly what is needed to achieve a school bus license and all endorsements would be very helpful so I know exactly what information is further needed and to study. Also any costs, background checks or fingerprinting would help out as well.

I am very pleased with just how helpful…Awesome.
I am very pleased with just how helpful these tests have been for me! Great resource for me,especially since driving a truck is a 2nd career for me ( former financial executive). Not only have I learned a lot, these practice tests have increased my confidence level 10 times to pass CDL General and Air Brake endorsement.

This program helped me to pass my CDL on my first TRY!
This program helped me to pass my CDL Permit on my first try. I aced the General Knowledge, Air Brakes and Tank Endorsements. I'm really grateful for this program.The study material was beyond helpful. As long as you follow their recommendations I do believe that you are guaranteed to pass.

I passed on the first try!
I knew very little about driving until I had 2 days to study for my test and felt very unprepared. This made everything so simple and I was able to pass on my first try. I was more than prepared to take the test after doing all the work online. This will help you pass the test and give you a ton of important driving information. I definitely recommend it if you feel like you dont even know where to start. That's how I felt. I feel like a commercial but I'm only writing this review because im genuinely happy with this purchase and with passing the test so easily.

Everyone.
Everyone, please take advantage of driving-tests.org! The course and information is direct and it will definitely help you pass the test! I literally started the course and took the CDL Knowledge and Air Brakes test 4 days later and passed! The study material is very similar to the test questions and I have 0 prior knowledge of trucks or trucking. I'm changing careers and the first step is getting CDL permit and drving-tests.org is the direct reason I passed the test! Please take advantage!

(FL) Last minute ELDT Hazmat Course.
Went to the DMV to take the Hazmat and Tanker test and they told me I was missing the ELDT course and without it they cant administer the Hazmat test. Prior to this I had already studied for the test and was ready to take it but I didnt think I needed the ELDT course because I had my CDL prior to the mandate. Turns out if you want to upgrade your license (adding endorsements) after the mandate you still need to take it. So I went home and looked up some courses and these people were charging freaking -. Then I found Driving-Tests charging just and I was skeptical so I looked them up on the TPR and they were legit. Did the course in about an hour since I already knew most of the questions, next morning went back to the DMV and passed my Hazmat test with zero questions wrong. I will say that the challenge bank feature was extremely helpful with the one-off questions that I hadnt seen before and I will be using this provider again when I go for my Doubles/Triples endorsement.
