What is the proper action when approaching a roundabout?

When approaching a roundabout, the appropriate action is to yield to traffic already in the roundabout. This is crucial for maintaining a smooth flow of traffic and preventing accidents. Vehicles already circulating in the roundabout have the right of way, which means that incoming vehicles must wait for a safe opportunity to enter the roundabout without disrupting the ongoing movement of traffic.

Yielding allows drivers to assess the situation in the roundabout, ensuring that there is a clear path to safely merge. This practice reduces the likelihood of collisions and creates a more efficient driving experience by minimizing unnecessary stops or delays.

Speeding up to merge quickly can create dangerous situations, as it may lead to conflicts with vehicles already in the roundabout. Turning on hazard lights is not a suitable action in this context, as hazard lights indicate a vehicle is stopped or experiencing a problem, which is not applicable in a roundabout situation. Coming to a complete stop before entering is also not required unless necessary due to the presence of pedestrians or other specific circumstances, as this can disrupt the flow of traffic within the roundabout. Therefore, yielding to existing traffic is the most effective and safe practice when navigating roundabouts.
