What should you do when you encounter a yellow arrow signal while turning left at an intersection?

When you see a yellow arrow while turning left at an intersection, it indicates that the signal is about to change, and you should clear the intersection quickly if you are already committed to the turn. This signal serves as a warning that the light is about to turn red, emphasizing the need for drivers to complete their turn safely and efficiently.

If drivers are approaching the intersection and see a yellow arrow but have not yet started their turn, it's often recommended to proceed with caution. However, commitment to the turn varies based on the situation, including the speed and proximity of oncoming traffic. Therefore, if you are already in the intersection, the best course of action is to clear it promptly to avoid being caught in a potentially dangerous situation once the light changes.

The other options do not align with the situation indicated by a yellow arrow. Stopping and waiting could lead to confusion or an unsafe scenario, particularly with vehicles behind you. Proceeding with caution without stopping may not be sufficient if there are already vehicles in the intersection, and yielding to oncoming traffic may also be inappropriate if you are already in the process of turning. Understanding the meaning of traffic signals and executing your response accordingly is crucial for safety at intersections.
