When approaching a traffic signal displaying a steady yellow arrow, drivers:
Should merge into a lane in the direction of the arrow.
Should slow to a stop, if it is safe to do so.
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 steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.
