Noob as noob gets. Non commercial class A license?

Yes, you need one. The chances of getting caught are slim, but that said I was pulled over just to have my license and ins checked by chp on the grapevine. Once in 4 years, but had I not had a class A it would be a "driving out of class" ticket, and the trailer parked at the side of the freeway with a 2 hour tow tag attached.
