For commercial drivers, driving in Maine can blend economic opportunity, scenes of rugged beauty – and particularly hazardous conditions in winter.

Important economic sectors in Maine include logging, fishing, agriculture, and manufacturing. Truck drivers transport lumber, seafood, potatoes, and manufactured goods to markets and distribution hubs in cities like Boston and New York. For truckers and bus drivers, the primary commercial route is Interstate 95. Other important commercial routes include U.S. Routes 1, 2, and 302.

U.S. Route 1 is a scenic route as well as a commercial route. But in winter, snowstorms, icy roads, and poor visibility can make I-95, U.S. Route 1, and U.S. Route 2 treacherous for commercial drivers. In northern Maine, where logging trucks operate, steep, winding roads can become particularly hazardous when they turn icy.

Want to obtain a Commercial Driver’s License (CDL) so you can start earning money as a commercial driver? One of the most important first steps you must take is to pass the official General Knowledge test on commercial driving theory. This is a necessary step for you to obtain a Commercial Learner’s Permit (CLP). Once you hold a CLP, you will be allowed to practice commercial driving under the supervision of a licensed CDL holder.

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.

About the Maine CDL

You have likely been advised to prepare for the General Knowledge test by studying the official Maine Commercial Driver License Manual (Maine CDL Handbook 2025). The manual does contain all the information on which you’ll be tested. You should read it. However, you may find that much of the information is hard to assimilate just by reading it. You should supplement your reading of the official manual with other study tools, such as the ones we can offer you.

This free Maine CDL permit practice test, one of several we offer, will assess your grasp of commercial driving theory. It’s based on the official CDL manual, just like the official knowledge test, and is up to date as of December, 2025. The 50 multiple-choice questions on this practice test will assess your understanding of such topics as driving maneuvers, cargo management, emergency preparedness, and vehicle inspections. The practice test differs from the official knowledge test primarily in the extra tools it gives you to help you learn, including an automated assistant that can offer you a hint if you get stuck and an explanation if you still miss a question. Plus, the practice test has no time limit. Take all the time you need to learn the material.

Be sure to try our other free Maine CDL permit practice tests too.
