Current issue: New T-intersection in PA, installed with three stop signs and three stop lines. One stop sign disappears (and completely so - no post or other trace left), but the stop line remains. No other traffic control signs or lights exist.
I was taught that the existence of a stop line, even without a corresponding stop sign, was indicative of a requirement to stop at an intersection. Now, the intersection is a hazard, with some people coming to a full stop, and others blowing right through.
Was I taught incorrectly?
