Final answer:
A flashing yellow arrow means that you are permitted to make a left turn after yielding to oncoming traffic and pedestrians.
Step-by-step explanation:
When encountering a flashing yellow arrow at an intersection, it indicates that left turns are permitted, but you must first yield to oncoming traffic and pedestrians before proceeding with the turn. This means that while you are allowed to turn left, you must be cautious and ensure the road is clear. This is crucial for both vehicle safety and pedestrian safety, as a traffic signal promotes orderly movement of traffic and allows pedestrians to cross at appropriate times. Therefore, the correct answer to what a flashing yellow arrow indicates regarding left turns is c) Yield to oncoming traffic and pedestrians before turning.
