On a traffic light, what does a flashing yellow arrow mean?

A flashing yellow arrow indicates that while you are allowed to turn left, you must first yield to oncoming traffic and any pedestrians in the crosswalk. This signal is used to provide flexibility for drivers while ensuring safety; it signals that turning left is permitted but requires caution. Drivers should approach the intersection with care, confirming that it is safe to make the turn before proceeding.

The presence of a flashing yellow arrow does not grant the same authority as a solid green light, which would allow a turn without any conditions. Thus, the requirement to yield distinguishes the flashing yellow arrow from other signals that may imply free movement without hesitation. This clarity helps prevent accidents at intersections by reminding drivers to be vigilant even when they have the opportunity to turn.
