Description

From the listing uploaded by “appupdater”.

To operate a bus or truck that has air brakes, you will be required to learn the information contained in the DMV’s CDL air brakes section of the study manual. To be qualified and licensed to pull a trailer with air brakes, you must also learn the information from the Combined Vehicles section of the manual.
