North Carolina requires state inspection within the 90 day period before getting/renewing your license plate. On the class C it is only a safety inspection, no emissions testing required. Class C are titled as a "passenger vehicle" and the cost is 13.00 plus tax. No sticker issued, all is computerized. Not sure if class A is the same procedure or not. I think the only real hassle would be the state's requirement that the vehicle has to be inside the building. After living here for 20+ years I think it is just a money grab, not a true inspection.
