What should a driver do when approaching a roundabout?

When approaching a roundabout, a driver should yield to traffic already in the roundabout. This is crucial because vehicles circulating within the roundabout have the right of way. Yielding helps maintain the flow of traffic and enhances safety by reducing the risk of collisions at the point of entry.

Understanding the correct behavior at a roundabout is vital for effective traffic management and safety. In doing so, drivers ensure they are following road rules meant to facilitate smooth transitions through these junctions. This rule supports a continuous flow of vehicles, which is one of the primary purposes of a roundabout. Thus, yielding to the traffic already present is essential for both the driver's safety and that of other road users.
