What is the benefit of the flashing yellow left turn arrow?
Use of the flashing yellow left turn arrows was recently
approved by the Federal Highway Administration after extensive
research conducted by the
National Cooperative Highway Research Program (NCHRP).
NCHRP research shows some of the benefits of the
installation of flashing yellow left turn arrows:
- High level of
understanding and correct response by left-turn drivers
(motorist may confuse the meaning of the circular green ball,
which can be mistaken as a protected left turn).
- Enables left
turn control to be varied by time of day.
- Improve safety at intersections.
How the new left turn arrows work
The new left turn signal consists of four arrows that are
used only for controlling left turning traffic. The flashing
yellow left turn arrow essentially takes the place of the
circular green ball indication for left turning drivers at the
intersection. Depending on the conditions at the intersections,
the flashing yellow left turn arrow may operate all of the time,
or for just a portion of the day when traffic volumes are light.
