Which statement about roundabouts is correct?

Answer: D — Yield to vehicles already in the circulating lane

When approaching a roundabout, the essential rule is to yield to traffic already circulating inside the circle. Vehicles in the roundabout have the right of way, so you slow down, look for a safe gap, and merge only when there is room. Once you’re in the circle, keep moving and follow your chosen exit, signaling as you approach it. You also need to yield to pedestrians as you reach crosswalks around the roundabout. The idea of always yielding to pedestrians isn’t accurate because you only yield where pedestrians have the right of way, and the fundamental safety rule is to yield to vehicles already in the circulating lane to merge safely.
