What must drivers do before entering a roundabout?

Before entering a roundabout, drivers must yield to traffic that is already in the roundabout. This is important for maintaining safety and allowing for the smooth flow of vehicles. Traffic within the roundabout has the right of way, and by yielding, drivers can avoid collisions and ensure that they integrate safely into the flow of traffic.

While some drivers may think it is appropriate to accelerate to merge or come to a complete stop, these actions can disrupt the traffic flow or lead to dangerous situations. Using a turn signal before entering is also not required until the driver is prepared to exit, further underscoring the importance of initially yielding to oncoming traffic in the roundabout.
