As a driver, what must you do in a roundabout?

When navigating a roundabout, yielding to traffic already within the roundabout is crucial for ensuring safety and smooth traffic flow. Roundabouts are designed to allow continuous movement of vehicles, and by giving way to those already circulating, you help prevent collisions and reduce congestion. This practice aligns with the principles of yielding to oncoming traffic in situations where vehicles are merging into roundabouts, promoting a more efficient transportation system.

The other choices do not adhere to the principles of safe driving. Speeding through without stopping undermines traffic rules and can lead to dangerous encounters with vehicles already in the roundabout. Ignoring the signs not only compromises your driving ability but also violates road safety regulations, which could result in penalties. Driving in reverse within a roundabout is not only unsafe but also against the rules, as it disrupts the flow of traffic and poses serious risks to both the driver and other road users.
