What action must drivers take when approaching a roundabout?

When approaching a roundabout, drivers are required to yield to the traffic that is already within the roundabout. This ensures a smooth flow of traffic and enhances safety for all vehicles and pedestrians. Yielding allows those in the roundabout the right of way, which helps prevent collisions and promotes a continuous circulation of vehicles.

Stopping before entering the roundabout is not necessary unless there is a stop sign or other traffic control in place, as stopping could lead to unnecessary delays. Entering without stopping is not safe or appropriate because it could cause confusion or accidents if drivers don’t yield. Additionally, using the left lane to enter is generally incorrect as roundabouts typically require drivers to use the right lane unless otherwise indicated, depending on the layout and signage.
