What does a flashing yellow arrow indicate?

A flashing yellow arrow indicates that you may proceed with caution in the direction of the arrow. It allows drivers to make a turn after yielding to oncoming traffic and pedestrians. This signal suggests that you should ensure the roadway is clear of any obstacles or vehicles before making your turn, allowing for a safe maneuver without the need to stop completely or wait for a solid green light.

In contrast, the other choices imply actions that do not align with the meaning of a flashing yellow arrow. The signal does not require a complete stop or permit turns without caution, and it clearly does not mean that all traffic must stop. Therefore, understanding the implications of such traffic signals is crucial for safe driving and adherence to the rules of the road.
