A yellow arrow serves as a warning that the situation is changing. Specifically, it indicates that the protection offered by a green arrow is coming to an end, signaling drivers to prepare to stop or to yield. It alerts drivers that they should slow down and be mindful of other vehicles and pedestrians before proceeding with their turn. This is crucial for maintaining safety on the road, as it encourages vigilance in anticipation of a signal change.

The other options present different meanings that do not align with the purpose of a yellow arrow. It does not allow for unconditional turns or suggest yielding to bicycles; rather, it emphasizes caution as the traffic signal shifts.
