What is the correct action when approaching a roundabout?

The correct action when approaching a roundabout is to yield to traffic already in the roundabout. This principle is fundamental to the safe functioning of roundabouts, as it allows for a continuous flow of traffic. Vehicles already circulating have the right of way, meaning that those entering must wait for a safe gap in the traffic.

Yielding helps prevent collisions and ensures that the roundabout operates efficiently. When you yield, you are assessing the flow of traffic and ensuring that it is safe to enter without disrupting the vehicles that are already on the roundabout.

In contrast, accelerating to merge quickly can lead to dangerous situations, as it may cause conflicts with vehicles already in the roundabout. Driving in the opposite direction goes against the fundamental design of roundabouts, which are intended for vehicles to move in a specific direction (usually counterclockwise in the United States). Stopping completely before entering may create unnecessary delays and disrupt traffic flow, especially if there is no oncoming traffic. Properly yielding instead of stopping allows you to enter the roundabout safely and efficiently when it is clear.
