Flashing Yellow Arrow Signal#

Flashing Yellow Arrow Diagram describing the various states.

Flashing yellow arrows are designed to indicate to drivers that they may proceed with caution after yielding to any oncoming traffic and pedestrians. These signals are typically used at intersections to allow drivers to make left turns, providing flexibility while maintaining safety. The flashing yellow arrow helps improve traffic flow by allowing turns during gaps in opposing traffic, enhancing intersection efficiency.

A Little Signal History#

When making a left turn, drivers traditionally see a green ball, which means you can make a left turn, but must yield to oncoming traffic. Research shows many motorists are confused by the green ball and either fail to yield or think they are not allowed to make the left turn.

Federal Highway Administration (FHWA) research found motorists more clearly understood what to do when presented with the flashing yellow arrow. Further, the flashing yellow arrow provides more flexibility in signal timing operations as it can be optimized for certain times of day. This ultimately improves safety and improves traffic flow.
