NEW!! Flashing Yellow Arrows (FYA)
Flashing yellow arrows are coming to town. As
part of the city-wide signal light upgrade and
synchronization project, the City of El Centro
will install flashing yellow left turn arrows in
addition to the standard red, yellow and green
arrows, at the intersection of Imperial Avenue
and State Street. The flashing yellow arrows are
part of an effort to increase traffic flow and
maintain safety.
The flashing yellow arrows will move more
vehicles through an intersection with less delay
by allowing drivers to turn left when there is a
gap in the oncoming traffic without having to
wait for the green arrow. Drivers making left
hand turns during a flashing yellow arrow must
yield to oncoming traffic and pedestrians and
turn with caution.
Here's what the new signals will look like and
what they mean
A solid red arrow (conventional) means STOP.
Drivers turning left must stop.    A solid
yellow arrow (conventional) means stop if it is
safe to do so.   A flashing yellow arrow (NEW)
means turns are permitted, but you must first
yield to oncoming traffic and pedestrians and
then proceed with caution.   A solid green arrow
(conventional) means turn left. Oncoming traffic
must stop. Do not go straight.
