When approaching a traffic circle, how should you decide when to enter?

When approaching a traffic circle, yielding to traffic inside the circle is essential for maintaining safety and the proper flow of vehicles. The vehicles already in the traffic circle have the right of way, which helps prevent collisions and ensures that those navigating the circle can do so without interruption.

Understanding how traffic circles operate is crucial. Vehicles that are circulating have established their path in the roundabout, and new arrivals must wait for a safe gap before entering. This helps keep the circle running smoothly, as entering without yielding could lead to potential accidents.

The other options do not align with the standard rules of traffic circles. Entering immediately without hesitation disregards the right-of-way rules and can create hazardous situations. Yielding to traffic outside the circle, while it might seem logical, is actually the opposite of what is required, as it doesn’t prioritize those who are already in the circle. Following the lead of cars in front may lead to miscalculations about timing and safety, as each driver's decision-making could vary. Each driver must independently assess the situation to ensure a safe entry.
