You may turn right on a red light provided you...?

Answer: B — Come to a complete stop and wait for the way to be clear

You may turn right on a red light as long as the way is clear and you have come to a complete stop. The other options are incorrect as they do not include the important step of fully stopping before proceeding. Option A is incorrect because signaling right is not enough to ensure safety. Option C is incorrect because while pedestrians should be taken into consideration, a complete stop is still required. Option D is incorrect because even if the way seems clear, a complete stop must be made before turning. Since turning involves entering a new lane and possibly crossing other lanes, a complete stop is necessary to assess the safety of completing the turn.
