What's new

Flashing yellow arrows

Flashing yellow arrow traffic signals feature a flashing yellow arrow in addition to the standard red, yellow and green arrows. When illuminated, the flashing yellow arrow allows waiting motorists to make a left-hand turn after yielding to oncoming traffic. Otherwise, these new traffic signals work the same as traditional signals. More about flashing yellow arrows.

Installed on non-signalized rural intersections, the systems reduce the number and severity of crashes with signs and flashing lights that warn drivers approaching an intersection to stop for cross traffic.
