Re: Licensing required to drive in North Carolina?? Still a bus.
It sounds like you do need the CDL given the current registration. I don't think you'll be driving it [legally] tomorrow. You will need to take a written test for the Class B CDL. On top of that there will be a passenger endorsement written test, and air brake written test, and possibly a school bus written test. After this you will receive your permit. The permit allows you to practice, but it's just like a regular learner's permit in that you will need to have another licensed driver with you. When I say licensed I mean they will need to be legally licensed to drive that vehicle (CDL, air brakes, passenger) and you will not be allowed to have passengers.
After you have learned for a while you will need to get a medical certificate. It's not a big deal and your doctor should be able to that. With permit in hand and a medical certificate you can then take the driving portion of the test. There is a typical pretrip portion for any Class B, but then you will also have to do the air brakes pre-trip as well as possibly the passenger vehicle pretrip. Beware...if you take the driving test in a bus with hydraulic brakes or a dump truck with air brakes, but no seating for 16 (never seen one WITH room for 16) you will need to take the whole test over again to get those certifications.
It's not hard to do, but unless you can get RV plates before tomorrow I think you're boned.
