Unless its under 26,000 lbs then we don’t give a shit. Trust me I get this call all the time about Joe Schmoe and his tow truck that has air brakes but it has a GVWR of under 26,0000 lbs and the office thinks he needs and air brake endorsement. Which is BS anyway because there’s no such thing as an air brake endorsement. Anything involving air brakes on a NY license is a restriction such as the L restriction “Invalid for air brakes” Or the L1 restriction “Invalid for class A air brakes” and the like. If you have an A B or C license that shows no restrictions you are okay to drive that respective vehicle with air brakes. It all boils down to what kinda vehicle you road test on basically.
