In a traffic circle, who has the right-of-way?

In a traffic circle, the vehicles that are already within the circle generally have the right-of-way over those entering the circle, unless otherwise indicated by traffic signs or signals. This rule helps to maintain a smooth flow of traffic and minimizes potential conflicts or accidents as vehicles navigate through the intersection. The concept is rooted in the idea that vehicles inside the circle are in a more advantageous and established position, so they should be allowed to continue their movement freely without interruption from incoming traffic.

The other options present conditions that do not align with standard traffic rules regarding right-of-way in circular intersections. For example, stating that vehicles inside the circle do not have the right-of-way except as indicated by signs or lights disregards the basic principle of operation in traffic circles. Additionally, suggesting that the right-of-way applies only to two-wheeled vehicles is misleading, as all vehicles inside the circle typically have precedence. Furthermore, establishing that vehicles inside the circle have the right of way over all incoming traffic without the exception of signage overlooks the crucial aspect of traffic management, which may dictate otherwise in certain scenarios.
