In North Carolina what are the requirements to operate a dump truck with a gvwr of less than 26000 lbs and equipped with air over hydraulic brakes?

This is a tricky one. The GVWR doesn't call for anything but a Class C driver's license--the cutoff for that is 26,001 pounds--but this truck has air brakes and you're driving it as part of your job--maybe your whole job. If I was driving this truck I'd want a Class B CDL and I'd take the air brakes test.
