When approaching a roundabout, which side do you enter on?

Answer: B — Right side

When approaching a roundabout, vehicles should enter it on the right side. This is consistent with the traffic flow in countries that drive on the right, such as the United States. Roundabouts are designed to allow for a smoother and safer transition through intersections by reducing the number of conflict points between vehicles. By entering on the right, vehicles yield to those already circulating in the roundabout, emphasizing the importance of yielding to traffic that is already in the circle before making your entry. This design helps in maintaining a continuous flow of traffic and reduces the likelihood of accidents compared to traditional intersections, where vehicles may come to a complete stop or face more potential conflicts. Additionally, roundabouts typically have signage and road markings that guide drivers to the proper entry point, reinforcing the requirement to enter on the right side. Understanding this rule is essential for navigating roundabouts safely and effectively.
