A Safer, More Efficient Left Turn Signal: Flashing Yellow Arrows

A Safer, More Efficient Left Turn Signal: Flashing Yellow Arrows

Posted on October 27, 2021

The Pennsylvania Department of Transportation (PennDOT) is implementing a new type of traffic signal to provide a safer, more efficient left turn for motorists. The flashing yellow arrow indication is a new type of display that will replace the circular green indication for left turns at signalized intersections.

Benefits of Flashing Yellow Arrow

• More intuitive to motorists

According to national data, can reduce left-turn crashes as much as 20%

• Keeps traffic moving by offering motorists more opportunities to make left turns

• Consistency with other states adopting the signal

The flashing yellow arrow is a new type of signal placed over the left turn lane at a signalized intersection. A flashing yellow arrow means YIELD to oncoming traffic and pedestrians and then proceed with caution. This indication replaces the common circular green indication for left turns.

Coming to an Intersection Near You

• First deployment in Lower Allen Township, Cumberland County

• PennDOT will monitor and adjust deployment tactics followed by widespread deployment for new and modified signalized intersections
