What must drivers avoid when making right turns?

Answer: D — Making a swinging wide turn to the left

When making right turns, drivers must avoid making a swinging wide turn to the left. This is because they run the risk of turning into the wrong lane or colliding with another vehicle. Option A is incorrect because drivers must come to a complete stop before turning right at red lights or stop signs. Option B is incorrect because following too closely is not necessarily related to making right turns. Option C is incorrect because drivers must always signal when turning, regardless of the direction.
