A steady yellow arrow pointing left indicates what to drivers at an intersection?

A steady yellow arrow pointing left serves as a warning to drivers that the left-turn signal is about to change to red. This light indicates that the current phase is ending, and drivers who intend to make a left turn should prepare to stop. It gives them a moment to react and adjust their plans accordingly, as it signals the transition from a permitted left turn to a situation where left turns will no longer be allowed.

The significance of the yellow arrow is to enhance safety at intersections by preventing sudden stops or impulsive actions, allowing drivers to be mindful of the changing traffic conditions ahead. Therefore, recognizing the meaning of the steady yellow arrow is crucial for making safe driving decisions at intersections.
