I was told by NC DMV that the class B license wasn't really necessary but went and got it anyway. Did my driving test at the Morehead City office and all they wanted to do was get a ride. When finished driving a few miles I asked if he wanted me to demonstrate brake testing and go through systems and the inspector said it want necessary as since it was a Prevost he was sure all was fine. I made him go through it anyway. A piece of cake. If your near Morehead City I can be of assistance.
