I once had a SC trooper in a unmarked car stop me for passing on the right (actually on the shoulder of the road). He was going to give me a ticket but let me off with a warning when I explained that I normally didn’t do that sort of thing but I would have crashed into the rear of his car if I didn’t. (He had decided to make a quick left turn off the highway.)
I told one that I didn’t see the stop sign because I was busy watching for pedestrians in the crosswalk. He let me go.
It used to be `70,if you got pulled over in SC in an out of state car you had to pay the ticket on the spot..broke me and had to return to Bragg missing a week end in Myrtle Beach
