To drive a truck or bus with air brakes, you need to know the information in the CDL Air Brakes section of the CDL manual. To pull a trailer with air brakes, you also need to know the information in the Combination Vehicles section - switch to these tests here. Air brakes use compressed air to make the brakes work. Air brakes are a good and safe way of stopping large and heavy vehicles, but the brakes must be well maintained and used properly.

The Air Brakes CDL Practice Test covers:
Air Brake System Parts, Dual Air Brake Systems, Inspecting Air Brakes and Using Air Brakes.

If you're just getting started, we recommend first getting your state CDL manual, then starting with the Classic Mode of each testing area. Quickly go through the Classic Mode of each CDL Air Brakes practice test and you'll have a good idea where you stand. Then navigate to the Practice Mode for more intense preparation. Finally, finish up in Exam Mode when you think you’re ready.
