Ready to show how well you know air brakes? Take our free Texas CDL Air Brakes Practice Test to show your mastery of this subject and your readiness to remove the air brakes restriction from your license. Removing that restriction will allow you to begin driving trucks with air brakes, which can increase your driving assignments and boost your income. To help you ensure you have the knowledge necessary to pass the air brakes test, we have filled our test with 25 questions covering all the important air brakes related topics, such as air brake systems, dual air brakes systems, air brake functions, air brake inspections and maintenance and much more. If you are going to be away from your vehicle for only a short time, do you still need to use the parking brake? Front wheel brakes are good to use under any conditions? These are examples of the types of questions that you will find on this practice test.

You need to answer at least 80% of the questions correctly to pass. If you don’t pass, you can take the test again and again until you do. We have also included answer explanations to help you learn the content and improve your score. Now you can preview the content and format of the real air brakes test before you visit the DMV.
