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