What should you do if you approach a roundabout?

When approaching a roundabout, yielding to traffic already on the roundabout is important for ensuring safety and smooth traffic flow. Vehicles that are already circulating have the right of way, and if you attempt to enter without yielding, you could create a hazardous situation that may lead to collisions.

By yielding to the traffic already in the roundabout, you allow for a more organized flow of vehicles, which helps to minimize congestion and reduce the risk of accidents. This approach is critical in maintaining safe driving practices and adhering to the rules of the road.

The other responses lack the proper guidance needed for safe roundabout navigation. Speeding up to beat other drivers can lead to dangerous situations, and stopping completely before entering the roundabout can disrupt the flow of traffic. Only giving way to vehicles on the right neglects the crucial rule to yield to all circulating traffic, regardless of their position. Thus, the correct action to take is to yield to traffic already on the roundabout.
