What does a flashing yellow arrow mean?

A flashing yellow arrow indicates that drivers may turn left after yielding to oncoming traffic and pedestrians. This signal is designed to provide more flexibility for turning while still ensuring the safety of all road users. The presence of the flashing yellow arrow communicates that the driver should approach the intersection with caution and be prepared to stop if necessary, particularly to allow oncoming vehicles or pedestrians to pass.

In contrast, the other options suggest different actions that don't align with the meaning of a flashing yellow arrow. For example, stopping is not required unless there is conflicting traffic or pedestrians. Turning right only or proceeding straight ahead are not applicable since the flashing yellow arrow specifically pertains to left turns, allowing them only when it is safe to do so. Understanding these signals is crucial for safe driving practices and proper navigation at intersections.
