Do not make the mistake of going to the DMV to obtain your North Carolina Air Brakes endorsement without doing practice tests first. Practice will give you the confidence and knowledge you need to proceed with ease. Then, you will be certain to receive your endorsement and advance your career. Your endorsement will open up opportunities that have been closed previously. Keep in mind it all starts with your endorsement, and a practice test makes it much easier to get that endorsement.

What to Expect with the Practice Test
Due to the fact that the North Carolina Air Brakes practice test is designed from the official North Carolina CDL manual, the questions are similar to the questions you will see on the authorized CDL test. The wording might be somewhat different, but the meaning remains the same. The practice test has 25 questions. Once you master these questions, you will be ready to move onto the official CDL test at the DMV.
As you take the test, it is important to make a note of the questions that you have problems with so you can study them after you complete the practice test. That way, you will be able to improve before you have to take the official test. Then, go back and retake the test to see if you get those answers right. Continue to do this until you are ready to take the actual test.

Getting Ready on Test Day
When test day finally comes, you might have some jitters. That is normal, but don’t let your nerves get the best of you. The best thing to do is to take your Air Brakes practice test one more time. Then, you will remember that you have the knowledge necessary to pass with flying colors Sometimes, a boost of confidence is all that you need to bring home your NC Air Brakes endorsement.
Good luck on your practice test, and keep in mind, you can take it as many times as you would like. Don’t rush the process. The practice test is here to help you as you move closer to getting your endorsement. Use it as a tool to help you achieve your goals.
