I know Florida has it - I think it's *FHP. Had to use it once when I was in high school and my mustang P.O.S. broke down on a road trip in the middle of nowhere! I think other states have it in certain areas, for example SC has their "DOT Assistance Zones" (or something) outside of Ft. Mill/Rock Hill, then also when you approach Columbia. Not sure if NC has it though.
