When approaching a roundabout, which direction should you always yield to?

Answer: B — Traffic already in the roundabout

When approaching a roundabout, it is essential to yield to traffic already in the roundabout. This is a critical rule because vehicles inside the roundabout have the right of way. This helps maintain a smooth flow of traffic and prevents collisions. Understanding this rule is important for safety, as it ensures that you do not interfere with vehicles that are already navigating through the roundabout. Yielding to traffic from the left, entering from the right, or emergency vehicles are not the correct procedures in this context. The specific instruction to yield to vehicles already in the roundabout helps clarify the functioning of circular intersections and makes it clear that the priority is to ensure safe passage for those who are already engaged in the roundabout's flow.
