How does a flashing yellow left-turn arrow work?
A flashing yellow arrow means that left turns are permitted, but drivers must first yield to oncoming traffic and pedestrians and then proceed with caution. The flashing yellow means the same thing as the green "ball" indication for a yielding left turn. The flashing yellow arrow does not replace the solid yellow arrow and its meaning.
Solid green arrow = Left turns have the right-of-way Drivers may proceed and must turn left. Oncoming traffic and pedestrians are stopped.
Flashing yellow arrow = Turns are permitted when there are acceptable gaps in traffic Drivers must yield to oncoming traffic and pedestrians, then proceed with caution.
Solid yellow arrow = Signal is about to change to red Drivers may only complete their turn if they legally entered the intersection and there are no conflicting vehicles or pedestrians.
Solid red arrow = Stop
Drivers turning left must stop.
