Well, since this old thread has been resurrected…
Since making this thread, that intersection was repainted. Someone in the leftmost turn lane has to turn into the leftmost lane on Greenville and someone in the right lane gets a choice of the middle or right. I work on the other side of town now though so I don’t pass by there very often anymore.
I also learned the hard way that it’s safer to turn into the right lane rather than the center when a drunk driver crossed the stripes and ran into my car (at another intersection that had very apparent stripes).
I’ve yet to find a law saying what to do if there aren’t stripes, but it’s also pretty rare that I see such an intersection without visible stripes. I’ve concluded that legally there are supposed to be stripes there and if they’ve worn off, it’s anybody’s guess.
