What is the correct procedure when approaching a roundabout?

When approaching a roundabout, the correct procedure is to yield to traffic that is already in the roundabout. This is essential for maintaining a smooth flow of traffic and ensuring safety for all road users. The vehicles within the roundabout have the right of way, which helps to prevent collisions and allows for efficient navigation through this circular intersection.

Yielding means you should slow down and give way to any vehicles traveling around the roundabout, allowing them to pass before you enter. This principle is designed to reduce the number of stops and delays typically associated with traditional intersections, thus enhancing traffic flow and reducing congestion.

The other options do not align with safe driving practices; speeding through a roundabout can lead to dangerous situations, making it hazardous for drivers and others around them. Going left is not a standard procedure in a roundabout since vehicles typically travel counter-clockwise. Lastly, making a U-turn within a roundabout is not allowed and could cause confusion and accidents, as roundabouts are not designed for such maneuvers. Following the correct procedure ensures safety for yourself and others on the road.
