What does a flashing yellow arrow in the left turn lane indicate?

The flashing yellow arrow in the left turn lane indicates that turning is allowed if the intersection is clear. This signal is a warning to drivers that they must yield to oncoming traffic and any pedestrians in the crosswalk before making the turn. It signifies caution, meaning that while you may proceed with the turn, you should observe the traffic conditions and ensure it is safe to do so.

Choosing this option reflects an understanding of traffic signals that require drivers to be vigilant while also allowing for movement when it is safe. This contrasts with other signals that impose stricter requirements, such as a solid yellow or red light, which would require stopping and prohibiting turns.
