What is the appropriate action if you approach a roundabout?

When approaching a roundabout, yielding to traffic already in the roundabout is the appropriate action. This is essential for ensuring smooth traffic flow and improving safety. Vehicles inside the roundabout have the right of way, meaning that those entering must wait for a gap in traffic before proceeding. This rule helps prevent collisions and allows for a more organized movement of vehicles.

Choosing to enter without yielding can lead to dangerous situations, as it forces vehicles already circulating to brake or swerve to avoid a collision. Similarly, making a U-turn in a roundabout is not only inappropriate but can also create confusion and disrupt traffic patterns. Stopping to wait for an opening can lead to unnecessary delays because roundabouts are designed to keep traffic moving. Thus, understanding the right-of-way rules at roundabouts is crucial for any motorist.
