What does a flashing yellow arrow indicate?

A flashing yellow arrow indicates that drivers can proceed with caution after yielding to any oncoming traffic and pedestrians. This signal is designed to provide guidance for making left turns when there may be oncoming vehicles. It alerts drivers that they should be prepared to stop, allowing for safe passage only when it is clear to do so.

This signal emphasizes the need for caution, as it does not provide the same level of assurance as a solid green arrow, which means it is safe to turn without hesitation. It requires drivers to assess their surroundings carefully before proceeding, ensuring no conflicts with other vehicles or pedestrians.
