Are you ready to earn your air brakes endorsement? Take our free Montana CDL Air Brakes Practice Test to find out. This test contains 25 questions covering such important air-brake related areas as the dangers of contaminated air supply, implications of disconnected airlines, implications of low air pressure readings, automatic fail safe devices and much more. Do you know what type of air is used by air brakes? Find out the answer to this question and more on our practice test.
Remember, when you earn your CDL you will have an air brakes restriction until you pass the endorsement test. That means you will not be able to operate any CMV with air brakes. Our air brakes practice test will evaluate your knowledge of how to properly inspect, use and maintain your vehicle’s air brakes so that you are prepared to pass the real test when you sit for it.
Our test is even formatted like the real test. It contains multiple choice questions with four possible answers and you have to select the correct one. You need to answer at least 20 of the 25 questions correctly to pass. Don’t worry, you can take this practice test multiple times to ensure you have the knowledge you need to pass the real test. Each time you retake the test the questions will be reordered. It’s time! Start taking our practice test now to accurately evaluate your current air brakes knowledge.
