What should you do if you are approaching a roundabout?

Speed up to merge with traffic.
Slow down and yield to traffic in the roundabout.
Proceed without reducing speed.
Sound your horn to alert other drivers.

The correct answer is: Slow down and yield to traffic in the roundabout.

When approaching a roundabout, it is essential to slow down and yield to traffic already in the roundabout. This ensures that you are prepared to make safe decisions based on the flow of vehicles within the roundabout. Roundabouts are designed to improve traffic flow and safety, allowing vehicles to move efficiently while minimizing the risk of collisions. By reducing your speed upon approaching the roundabout, you give yourself adequate time to assess the situation and integrate smoothly with the circulating traffic. Yielding means you must allow any vehicles currently in the roundabout to pass before you enter, ensuring a harmonious flow of traffic without stopping abruptly or forcing your way in. This approach enhances safety for all road users, including pedestrians. Understanding the function of roundabouts is crucial; they are intended to reduce the number of conflict points compared to traditional intersections, making it necessary for drivers to yield as a key principle for effective navigation.
