Medium-weight Class B vehicles and heavy-weight Class A vehicles are equipped with air brakes to make controlling speed easier for the driver. If either of these vehicle classes are what you are aiming for, you can read about air brake repair, maintenance, application and stopping distances in the Air Brakes section of the DMV handbook. Your understanding of this material will be assessed during the mandatory Class A and Class B DMV CDL air brakes test.
