What is the proper reaction if you encounter a roundabout?

When approaching a roundabout, the proper reaction is to yield to traffic that is already circulating within the roundabout. This ensures a smooth flow of traffic and minimizes the risk of collisions. Vehicles inside the roundabout have the right of way, and by yielding, you allow them to continue moving without interruption.

Entering a roundabout without yielding, stopping in the middle of it, or making a left turn within the roundabout are not appropriate actions. Not yielding can lead to accidents since traffic inside the roundabout is already in motion. Stopping in the middle would disrupt the flow and create hazards for other drivers. Additionally, making a left turn is not a typical maneuver within a roundabout; you should enter from the right and navigate around to exit at your desired point, typically using right turns or continuing straight. Understanding the yield rule is crucial for safe navigation of roundabouts.
