What action should you take when you encounter a roundabout?

When approaching a roundabout, the correct action is to yield to traffic that is already circulating within the roundabout. This is crucial for ensuring a safe and smooth traffic flow. Vehicles that are already in the roundabout have the right of way, meaning that any vehicles entering the roundabout must allow them to pass before proceeding. Yielding helps to prevent collisions and maintains an orderly movement of traffic.

Entering a roundabout without stopping can create dangerous situations, especially if another vehicle is already in the roundabout. Driving in the opposite direction of the traffic flow is inherently unsafe and goes against all traffic laws, as roundabouts are designed for vehicles to circulate in a counter-clockwise direction. Increasing speed to merge quickly may seem like a good idea to avoid delays, but it can lead to accidents as it can catch other drivers off guard and lead to conflicts at the entrance of the roundabout.

Understanding this principle of yielding in a roundabout is essential for both safety and compliance with traffic regulations.
