What does a flashing yellow arrow indicate to drivers?

A flashing yellow arrow signals to drivers that they may make a turn in the direction of the arrow, but they must first yield to oncoming traffic and pedestrians. This means that while the driver has the option to turn, they must ensure that it is safe to do so by checking for other vehicles or individuals who have the right of way. The flashing yellow arrow essentially provides a cautionary indication that turning is permitted, but requires the driver to exercise care and attentiveness.

Other possible options suggest different directives, such as requiring a complete stop or prohibiting a turn, which do not align with the meaning of a flashing yellow arrow. So, it is crucial for drivers to understand this signal as a prompt for attentiveness rather than an outright instruction to stop or proceed without yielding.
