Did you know that the air compressor is connected to your vehicle’s engine through gears or a v-belt? If this is new information to you, then you need to study more prior to the CDL air brake test! You can expect to be tested on the parts of an air brake system, their function, and upkeep. Do you want the opportunity to see the types of questions that will be asked before exam day? Take our Free Maine CDL Air Brake Practice Test and you will have access to 25 authentic multiple-choice questions! Each question comes with four possible responses and detailed feedback based on your response. If you can answer 80% of the questions correctly, then you are ready for the real thing!

We used the official Maine CDL Handbook to create our test, the same reference that the DMV exam uses. If you want to test your skills before the exam, try our Free Maine CDL Air Brake Practice Test!
