When approaching and entering a roundabout, a driver should yield to the traffic that is already circulating within the roundabout. This means that as you enter, you must look to your left and allow vehicles that are already in the roundabout the right of way. This rule is in place to ensure a smooth flow of traffic and to minimize the potential for collisions.

Yielding to existing traffic allows for safe merging into the roundabout, which is designed to facilitate continuous movement and reduce the likelihood of congestion. It is crucial for maintaining order and safety within such intersections since all arriving vehicles must be cautious of those already navigating through the roundabout.

Accelerating to merge quickly can create dangerous situations and disrupt the flow of traffic; stopping and waiting for a signal is generally not applicable in a roundabout context, as they operate without traffic signals; and using the left lane to enter is incorrect, since the right lane is typically designated for entry into the roundabout. Thus, yielding to traffic already in the roundabout is the proper and safe practice when entering.
