Flashing left-turn yellow arrows will soon be coming to traffic lights at 10 intersections in Fayetteville, thanks to the Georgia Department of Transportation.
The new scheme is intended to improve safety by reducing crashes, and it also will increase traffic flow, according to DOT. The new lights will, however, take some getting used to by local motorists.
The solid red and green arrows are self-explanatory: you can turn left on a green arrow and you must stop on a red one. It’s the yellow arrows where things get a bit trickier.
