Is your knowledge of air brakes good enough to pass the endorsement exam? Take our free Rhode Island CDL Air Brakes Practice Test to see where you stand. This test covers air brake systems, air brake usage and more. If you pass this test you are ready to pass the actual endorsement test. Earning that endorsement will allow you to remove the air brakes restriction from your license and allow you to begin driving trucks with air brakes. To get you ready to pass, our practice test features 25 multiple choice questions drawn from the content of the Rhode Island CDL Handbook. That is the same resource that is used for the real test. Our test has questions like these: The cut-out level and cut-in level for the air compressor governor should be roughly what pressure per square inch (PSI)? Compressed air usually contains what substances that are harmful to the brake system?

A passing score on our practice test requires that you answer at least 80% of the questions correctly. If you don’t pass or just want to check your knowledge another time, you can take this test again. Unlimited attempts are allowed. There are also answer explanations and a progress tracker to further help you study. Taking this test is a great way to preview the content and format of the real test before you visit the DMV and pay your test fee. By taking this test you will also build your confidence and help ensure that you are ready to pass. Take the practice test now to assess your air brakes knowledge.
