What action should be taken when approaching a roundabout?

When approaching a roundabout, the appropriate action is to yield to the vehicles already in the roundabout. This is crucial for ensuring safe and efficient traffic flow. Roundabouts are designed to keep traffic moving smoothly, and yielding allows drivers already circulating in the roundabout to continue without interruption, reducing the potential for collisions.

Entering the roundabout without yielding can lead to unsafe situations where drivers may collide with vehicles that have the right of way. Stopping before entering a roundabout is generally unnecessary and can create confusion, as it disrupts the flow of traffic and may lead to rear-end collisions. Additionally, driving at high speed to clear the intersection goes against the fundamental principles of roundabout safety and can increase the severity of accidents.

By yielding appropriately, drivers contribute to a more efficient transportation system while maintaining safety for all road users.
