Black Hills Traffic Signals Displaying Flashing Yellow Arrows


RAPID CITY, S.D. – The South Dakota Department of Transportation is advising motorists that newly installed traffic signals in Rapid City, Black Hawk, and Belle Fourche use the new flashing yellow arrow as part of the signal systems.


A flashing yellow arrow means left turns are permitted, but drivers must first yield to oncoming traffic and pedestrians before proceeding with caution. The system replaces the solid green “ball” indication as a signal for motorists to proceed through an intersection.


The solid yellow arrow means motorists should prepare to stop or complete left turns if already in the intersection.


Flashing yellow arrow signals have already been installed at several locations in the Black Hills including Catron Boulevard in Rapid City, Peaceful Pines Road in Black Hawk, and on Highway 85 in Belle Fourche.


Traffic signals displaying the flashing yellow arrow in the future are located at two intersections on Highway 16 in Custer and at two intersections on Jackson Boulevard in Rapid City. Those signals are expected to be operational later this year.


The change to flashing yellow arrows is the result of a national study done for the Federal Highway Administration which demonstrated that the new signals help reduce left turn crashes by 35 percent.
