You will need to learn about air tank pressurization, tank draining procedures, air brake inspection prior to journey commencement, how to safely apply air brakes and calculating stopping distances, in addition to system components and basic repair skills which you may need while on the road.

As you know, there are many different CDL endorsements to choose from and figuring out which ones you need for you desired career path can be tricky. However, if you require any license endorsements for your chosen driving job at all, it is very likely that the Air Brakes L endorsement is among them. The Air Brakes qualification is required by more commercial drivers than all other endorsements combined, which is one of the reasons our Vermont air practice test is so popular. If you aim to work with a flat-bed, box-truck, tanker vehicle, city bus, combination tractor-trailer, livestock vehicle, school bus or any other Class A or Class A vehicle, you’re going to need an air brakes endorsement. It is a mandatory addition to all Class A and Class B permits, as every vehicle within these two upper weight categories is legally required to use air brakes. Therefore, when the CDL general knowledge VT exam is out of the way you should begin working with our DMV CDL practice test air brakes quiz at the earliest available opportunity.

CDL general knowledge is the only DMV permit test which you must pass prior to sitting the L endorsement exam.
