What should you do when approaching a roundabout?

When approaching a roundabout, yielding to traffic already in the roundabout is the proper action to take. This is crucial for maintaining a safe and efficient flow of traffic. Vehicles in the roundabout have the right of way, and yielding allows for a smoother transition into the roundabout when there is a safe gap.

Entering a roundabout rapidly can disrupt traffic and increase the risk of crashes, as other drivers may not expect or be prepared for a vehicle to suddenly enter at high speed. Stopping and waiting for a green light is not applicable, as roundabouts do not use traffic signals in the same way intersections do; they operate on the principle of yield, not stopping for a signal. Turning on hazard lights is not appropriate when approaching a roundabout, as it can confuse other drivers regarding your intentions. Thus, yielding ensures that you respect the established traffic patterns and enhance overall road safety.
