Green, yellow and red. We're all familiar with standard traffic lights. But South Dakota motorists may not recognize a new signal - headed to an intersection near you.
A new traffic signal (a yellow flashing arrow) is making its way into more intersections in the Black Hills.
The flashing yellow arrow indicates left turns are permitted but drivers must yield to oncoming traffic and pedestrians.
The addition of the new arrow is statewide and aimed at increasing safety at intersections.
"A national study shows the yellow arrow helped reduce left hand turn crashes by 35 percent," said John Matthesen, a Region Traffic Engineer with the Department of Transportation.
The new lights have already been installed on Catron Boulevard in Rapid City, Peaceful Pines Road in Black Hawk and Highway 85 in Belle Fourche.
DOT officials say they hope to eventually bring the new traffic light to all busy intersections in the state.
