CDL Air Brakes Endorsement Practice Test FAQs:
What is on the CDL air brakes endorsement test?
The air brakes endorsement test includes two parts: a written knowledge test and an in-vehicle practical exam. Your written test will ask questions on the laws and safety procedures associated with air brakes-equipped vehicles, and the practical exam will show your ability to put that knowledge into action.
What CDL class do I need to drive an air brakes vehicle?
The class of CDL you need is highly dependent upon the gross vehicle weight rating (GVRW) of the vehicle you’ll be driving. Many air brakes-equipped commercial vehicles are larger semi-trucks, which typically require a Class A CDL. However, you may instead drive a smaller box truck also equipped with air brakes, which often falls under a Class B CDL.
Is the air brakes endorsement required for all commercial drivers?
No, an air brakes endorsement is only required if you’re planning to drive vehicles equipped with air brakes.
