Motorists along South Carolina’s streets and highways will soon see a new style left turn traffic signal head to improve safety and visibility. The S.C. Department of Transportation (DOT) is beginning to install a new style traffic signal head, commonly called a "Flashing Yellow Arrow" (FYA) left turn signal head. The first FYA signal head was installed May 1 in Richland County at the intersection of Farrow Road (S.C. 555) and Parklane Road at the Carolina Research Park.
