You see a yellow arrow at an intersection. This arrow means:

Answer: A — You are allowed to make a protected turn

A yellow arrow at an intersection typically designates a protected turn, which means that you are allowed to turn in the direction of the arrow while oncoming traffic is stopped by a red light. Option B is incorrect because a yellow arrow does not indicate that the light is about to turn red, as that would be indicated by a solid yellow light. Option C is also incorrect because a yellow arrow does not give instructions to move forward, it only applies to drivers who wish to make a turn. Option D is incorrect because a yellow arrow by itself does not require drivers to stop, as that would be indicated by a red arrow or red light.
