When a red signal light with a green arrow is shown at an intersection it means

Answer: A — Stop and wait for green signal before making turn in the direction of the arrow

This means that at the intersection, the traffic light is showing both a red signal and a green arrow, indicating that you must come to a complete stop and wait until the traffic light turns green before making a turn in the direction of the arrow. Option B is incorrect because the green arrow is not a signal for pedestrians, but rather for vehicles making turns. Option C is incorrect because coming to a stop is not enough, you must wait for the green signal before proceeding. Option D is incorrect because you must come to a complete stop before making the turn, not proceed with caution.
