How should a driver react if the yellow arrow changes while they are in the intersection?

When a driver sees a yellow arrow while already in the intersection, it indicates that the signal is about to change to red. The most appropriate action in this scenario is to make the turn safely if possible. This allows the driver to clear the intersection without causing a potential traffic conflict or obstruction.

The yellow arrow serves as a warning, suggesting that the driver should prepare to stop but also acknowledges the current position in the intersection. If a driver is already committed to a turn, they should complete the maneuver safely instead of abruptly stopping or backing up, which could lead to collisions with vehicles behind them or interfere with the flow of traffic.

Other options suggest actions that may not be safe or appropriate once a driver is within the intersection. For instance, stopping immediately could create a hazardous situation if vehicles behind are not prepared for a sudden stop, and yielding to oncoming traffic may not be feasible if the driver is already committed to the turn. Therefore, safely completing the turn is the most logical and safe choice in this context.
