Final answer:
A flashing yellow turn arrow warns drivers to yield to oncoming traffic, which has the right-of-way, and to proceed with caution.
Step-by-step explanation:
A flashing yellow turn arrow indicates to drivers that they should proceed with caution because oncoming traffic has the right-of-way. In traffic contexts, this means you are allowed to make the turn but must yield to other vehicles and pedestrians since oncoming traffic typically has a green light or the priority in the flow. It serves as a reminder for drivers to be vigilant before completing their turn, ensuring that the intersection is clear of hazards.
This is in line with traffic safety measures designed to reduce speed, protect pedestrians, and prevent accidents indicated by local police reports highlighting the frequency of incidents at intersections that lack appropriate signaling.
A flashing yellow turn arrow indicates that oncoming traffic has a yield. Observe the traffic coming from the opposite direction, then proceed with caution when it is safe to do so.
