What must you do when entering a roundabout?

When entering a roundabout, it is essential to yield to the traffic already within the roundabout. This rule helps ensure a smooth flow of traffic and reduces the risk of accidents. Vehicles that are already circulating have the right of way, which allows them to maintain their speed and prevents unnecessary stops and interruptions in the traffic flow.

Yielding before entering allows you to assess the traffic situation and merge safely into the roundabout when there is an adequate gap. This practice helps to facilitate safe and efficient movement for all road users within the roundabout, including pedestrians and cyclists who may be crossing at the exits.

Other options, such as speeding up to merge or stopping entirely, do not align with the correct practices for navigating roundabouts effectively. Signaling right to enter may also confuse other drivers since it is important to signal when exiting the roundabout rather than upon entry.
