Cdl written test for buses

Air brakes are very important. If you don't have it you probably will not be able to use a heavy truck or bus in America because there are none that don't use airbraking systems. That is one restriction (Along with auto only, non manual) you do not want.

 

You have to have airbrakes, which means you need to touch up and study the subject until you pass that particular test, at that point the restriction should be taken off. It is a important component to trucking, and sometimes life depends on your knowledge of the system among other things.

 

I’m not a bus driver but I guarantee you need that ability to use air brakes unless it is small. Also if you are planning on driving a full size coach/bus you need a Class B not C.

 

Regarding the air brake test questions, watch a JJ Keller / or similar YouTube on pre-trip inspection on airbrakes. It is a lot easier to remember when you actually know what the components are and what you are looking for instead of just memorizing text.
