About this test

9 min to complete
Available in EN and ES

Louisiana is one of the best states in the nation for truck driving, with a robust amount of exports needed all over the country and internationally. As a Louisiana truck driver, the best way to support oneself is to have a license with the fewest amounts of restrictions and that means learning how to drive with air brakes. To get a CDL with an air brakes qualification, you should take practice exams early and often. Then on the day of the real exam, you will find that you’re incredibly comfortable with the questions already. This 30 multiple-choice question quiz, complete with hints and explanations, is closely based on the Louisiana Commercial Driver’s License Manual’s series of questions about air brakes, so take it as many times as you need to get a perfect score, and you’ll be on your way to driving with air brakes starting today!

To fully understand the Air Brakes endorsement process and to master the material for the written exam, explore our detailed guides on the Air Brake endorsement and the Air Brakes written test.
