What must drivers do at a roundabout?

At a roundabout, drivers must yield to traffic that is already circulating within the roundabout. This rule is crucial for maintaining a smooth flow of traffic and ensuring safety for all road users. Cars already in the roundabout have the right of way, allowing them to continue without interruption. Yielding gives drivers the opportunity to assess the situation and enter the roundabout at an appropriate time, minimizing the risk of collisions.

While making a full stop before entering, entering without yielding, or only yielding to pedestrians may seem like potential strategies, they do not align with the proper driving rules for roundabouts. Making a full stop unnecessarily can cause delays and disrupt the flow of traffic, while entering without yielding can lead to dangerous situations and accidents. Finally, while it is important to yield to pedestrians, this does not replace the necessity of yielding to vehicles already in the roundabout, which is a fundamental aspect of roundabout navigation.
