What is the correct way to approach a roundabout?

The correct approach to a roundabout involves yielding to traffic that is already circulating within the roundabout before entering. This ensures that you do not disrupt the flow of traffic and helps maintain safety for all road users. By yielding, you are allowing vehicles that are already in the roundabout to continue moving, which is critical for preventing accidents and ensuring a smooth traffic flow.

This approach emphasizes the importance of awareness and caution when navigating roundabouts. It requires drivers to assess the situation and only enter when it is safe, thus reducing the risk of collisions. This method fosters a predictable and organized pattern of traffic which benefits all drivers.

The other options indicate unsafe or improper driving behaviors. Entering without looking at oncoming traffic disregards safety and could lead to accidents. Driving straight through without stopping may cause conflicts with vehicles in the roundabout, while stopping in the middle can confuse other drivers and create hazards. Therefore, yielding to traffic already in the roundabout and proceeding cautiously is the best and safest method.
