Yellow Flashing Lights Improve Safety, Reduce Traffic

In a continual effort to provide the safest roadways, the Town of Marana is installing flashing-yellow left-turn turn arrows at select signalized intersections and corridors. 

Numerous turn signals are being updated to include flashing-yellow arrow signals to create a safer, more efficient left-hand turn. When on, this flashing yellow arrow means a vehicle is allowed to cautiously enter an intersection only to make the turn indicated by the arrow, but the driver must first yield to oncoming traffic and pedestrians, then proceed with caution.

 The new flashing-yellow arrow provides a more direct message than the traditional circular green indication for turns.  YIELD to oncoming traffic and pedestrians when you see it flashing.  National studies have revealed that it reduces confusion, because the turn-lane display is no longer the same indication as the adjacent through lanes.


A national study demonstrated drivers had fewer crashes when using the Flashing-Yellow Arrow left-turn signal than with the traditional circular green left-turn signal, because some drivers perceive any green signal to mean GO.  These flashing-yellow arrows have been shown to help drivers make fewer mistakes.  They keep motorists safer during heavy traffic and reduce delays when traffic is light.

Less traffic delay

Motorists have more opportunities to make a left turn with the flashing yellow left-turn arrow than with the traditional yielding left-turn indications, which keeps traffic moving.

More flexible

The new yellow-flashing turn display provides more options to most effectively handle all types of traffic volume and reduce traffic back-ups.
