What is required of drivers approaching a roundabout?

Drivers approaching a roundabout must yield to both pedestrians and traffic already in the roundabout. This is crucial for ensuring safe navigation through these intersections. Roundabouts are designed to improve traffic flow and reduce the likelihood of accidents, and yielding to oncoming traffic prevents collisions and allows for smooth entry into the roundabout.

Additionally, yielding to pedestrians enhances safety for all users of the roadway, ensuring that those crossing at or near the roundabout can do so without risking their safety. This practice promotes a cooperative driving environment, which is essential in multi-lane situations such as roundabouts, where vehicles are moving in a circular pattern.

Entering a roundabout without yielding, as suggested in other options, risks accidents, and ignoring pedestrians and bicycles undermines the safety features that roundabouts are intended to provide. Therefore, knowing to yield upon approach is fundamental for drivers to navigate roundabouts effectively and safely.
