What is the procedure when you must turn left at a stoplight?

Answer: D — Signal, move over to the left lane, and proceed

When making a left turn at a stoplight, option D is the correct procedure to follow. This is because turning left requires you to move to the lane furthest left, so you can safely cross the intersection. Option A is incorrect because just signaling and staying in the left lane may not allow for a safe and uninterrupted turn, as other vehicles may still be traveling in that lane. Option B is incorrect because staying in the right lane will not allow for a left turn at all. Option C is incorrect because simply waiting for traffic to clear does not ensure a safe and legal left turn. It is important to signal and move to the left lane before making the turn to clearly communicate your intentions to other drivers and ensure a safe turn.
