What is required when approaching a roundabout?

When approaching a roundabout, the key requirement is to yield to traffic that is already circulating within the roundabout. This is important because vehicles inside the roundabout have the right of way, allowing for a smoother flow of traffic and reducing the potential for collisions. Yielding ensures that you can safely merge into the roundabout once there is a gap in traffic.

Understanding the dynamics of roundabouts is essential for safe navigation. Speeding up to merge with traffic can create hazardous situations if the merging driver does not accurately judge the speed and distance of approaching vehicles. Signaling left to indicate a left turn is not applicable when entering a roundabout; instead, the signal should be used when exiting the roundabout. Stopping before entering is unnecessary unless a stop sign or other traffic control is present, as this could disrupt the flow of traffic in the roundabout. Hence, yielding to existing traffic is the most crucial action when navigating into a roundabout.
