NCDOT Installs New Traffic Signals at Elkin Intersection

Flashing yellow arrow turn signals designed to reduce left-turn accidents

SHELBY -The N.C. Department of Transportation has recently installed new left-turn traffic signals at the intersection of U.S. 21/Bridge Street and N.C. 268/CC Camp Road in Elkin. The new flashing yellow arrow signals are designed to reduce accidents at signalized intersections and to improve driver understanding of left-turn traffic signal displays.

The new traffic signals vary from the traditional green arrow and green circular displays, which indicate protected and permitted left turns. The new left-turn design has a flashing yellow arrow between the solid green and solid yellow arrows on the signal. When the flashing yellow arrow is displayed, left turns are permitted, but drivers must yield to oncoming traffic and pedestrians.

Since 2005, the NCDOT has installed hundreds of these left-turn signals with flashing yellow arrows. This design was first installed in 2005 at the employee/visitor entrance to Wake Medical Center in Raleigh as part of a national study sponsored by the Federal Highway Administration. Studies at sites with the flashing yellow left-turn signals have shown a 37 percent decrease in accidents involving left turns.
