Maine is a great state for truck drivers, with beautiful roads, not too much traffic, and a significant amount of exports that need to get out of the state to the rest of the country — from lumber to blueberries. To make the most of your Maine CDL, you want to be able to drive vehicles with or without air brakes, so that you are not limited. This quiz is closely based on the questions in the Maine Commercial Driver License Manual with explanations that you should read closely. It is multiple-choice, just like the real air brake exam, so that you can get comfortable with this format. Practice early, often, and until you get the score that you want. Soon, you’ll be driving a vehicle with air brakes safely and proudly on the Maine roadways!
