Since driver licensing rules are SO VERY State specific, the only way you can get a true answer is from YOUR State driver licensing agency.
Given personal experiences in several different states, I hope you have good luck in finding somebody who actually knows what your local rules are.
I could tell you what the Montana rules are, but that won't do you a bit of good!
