What should you do if you approach a roundabout?

When approaching a roundabout, the correct action to take is to yield to traffic already inside the roundabout. This is essential for ensuring safe merging and flow of vehicles. By yielding, you allow those who are already navigating the roundabout to maintain their path without interruption.

Roundabouts are designed to improve traffic flow and reduce collisions compared to traditional intersections by allowing continuous movement. When you yield, you assess the traffic conditions and only enter the roundabout when it is safe. This practice minimizes the potential for accidents and enhances the efficiency of the road system.

In contrast to this correct answer, speeding up to enter the roundabout disrupts the flow and increases the risk of collisions. Stopping and waiting for all traffic to clear can lead to unnecessary delays and does not align with the intended purpose of roundabouts, which is to keep traffic moving. Entering without yielding is unsafe and goes against traffic laws designed to protect all road users, potentially leading to accidents.
