When approaching a roundabout, yielding to traffic that is already in the roundabout is crucial for ensuring the flow of traffic and safety. Roundabouts are designed to facilitate continuous movement and reduce accidents. Vehicles within the roundabout have the right of way, allowing them to flow smoothly without stops. By yielding, you allow those vehicles to continue their path, and you can then safely enter the roundabout when it is clear. This practice significantly decreases the likelihood of collisions and promotes efficient traffic movement.

Entering the roundabout without yielding would disrupt this flow and could lead to dangerous situations. Similarly, attempting to speed up to merge quickly can create unsafe conditions and increase the risk of accidents. Ignoring traffic signs is never a safe practice and can lead to confusion and potential hazards for all road users. Therefore, yielding to traffic already in the roundabout is the best and safest approach when navigating these intersections.
