What must you do when approaching a roundabout?

When approaching a roundabout, yielding to traffic that is already in the roundabout is the essential action to take. This practice ensures a smooth flow of vehicles and minimizes the risk of collisions. Vehicles in the roundabout have the right of way, allowing them to continue moving without interruption. By yielding, you ensure that you can enter the roundabout safely without disrupting the flow of traffic.

This approach helps maintain the efficiency of the road system, as roundabouts are designed to improve traffic flow compared to traditional intersections. By understanding this requirement, drivers can navigate roundabouts more effectively, leading to safer road conditions for everyone involved.
