When approaching a traffic signal displaying a flashing yellow arrow, drivers:
Should merge into a lane in the direction of the arrow.
Should come to a complete stop.
May turn left after yielding to oncoming traffic and pedestrians.
Have the right-of-way and may expect oncoming traffic to stop for them.
A flashing yellow arrow indicates that left turns are allowed in the direction of the arrow. However, the oncoming traffic has a green light and you must yield to oncoming traffic and pedestrians.
