What should a driver do when approaching a roundabout?

When approaching a roundabout, yielding to traffic already in the roundabout is crucial because it helps ensure a smooth flow of vehicles and enhances safety for all road users. Traffic within the roundabout has the right of way, which means drivers entering the roundabout must wait for a safe gap in the circulating traffic before proceeding. This practice prevents collisions and helps maintain the efficient movement of vehicles.

This approach is based on the design of roundabouts, which are meant to reduce conflict points compared to traditional intersections, allowing for safer and quicker transitions through the intersection when drivers follow the right yielding protocols. The other options—speeding up to enter quickly, turning on hazard lights, and stopping completely before entering—would create potential hazards and disrupt the orderly flow of traffic designed in roundabouts.
