What is the proper action when approaching a roundabout?

When approaching a roundabout, the proper action is to yield to traffic that is already circulating within the roundabout. This ensures a smooth flow of traffic and minimizes the risk of accidents. Vehicles in the roundabout have the right of way, so allowing them to pass before you enter helps maintain order and efficiency in traffic movement.

Yielding is crucial because roundabouts are designed to reduce the points of conflict and improve safety for all road users. This practice helps in managing the speed of vehicles and promotes better traffic flow. Properly yielding also means that drivers can assess gaps in traffic and enter the roundabout safely.

In contrast, stopping before entering and waiting for a signal, entering without yielding, or speeding up to get through quickly could lead to dangerous situations or impede the flow of traffic. These actions go against the purpose of a roundabout, which is designed to keep traffic moving smoothly without the need for traffic signals.
