The CDL air brake test determines if you possess sufficient knowledge of complex commercial braking systems. If you want to pass the exam, you will need to know the parts of an air brake system, how to operate braking systems, and proper inspection. Our Free Hawaii CDL Air Brake Practice Test gives you the opportunity to test your knowledge before taking the actual exam. We referenced the official Hawaii CDL Handbook to create 25 multiple choice questions that will prepare you to attain your endorsement. Each question comes with a detailed description of a correct response. With a passing score of 80% or above you are in good shape to pass the real thing!
