What should a driver do when approaching a roundabout?

When approaching a roundabout, it is essential for a driver to yield to traffic that is already circulating within the roundabout. This ensures a smooth flow of traffic and helps prevent accidents. The design of roundabouts is meant to facilitate continuous movement, allowing vehicles to merge and exit at their chosen points without the need for traffic signals or stop signs.

Yielding to the traffic already in the roundabout is crucial because vehicles within the roundabout have the right of way. This practice helps maintain safety and efficiency in the roundabout's operation, allowing vehicles to enter only when it is safe to do so. By following this rule, drivers help ensure that there is minimal disruption and that all vehicles can navigate the roundabout safely.

Other actions, such as entering without yielding, stopping before entering, or turning on hazard lights, do not adhere to the proper rules of the road and could lead to confusion or accidents within the roundabout system.
