What indicates that a driver must yield at an intersection?

A stop sign is a clear and universally recognized indicator that a driver must yield at an intersection. When approaching a stop sign, the driver is required to come to a complete stop, assess the intersection for other vehicles or pedestrians, and yield the right of way to any traffic or pedestrians that may be present. This rule is crucial for ensuring safety in intersections, which can be high-risk areas for accidents.

In contrast, a solid green light indicates that the driver has the right of way to proceed without stopping, while a flashing yellow light alerts the driver to proceed with caution but does not require them to stop. A flashing red light typically functions similarly to a stop sign, indicating that the driver must stop, but the explicit requirement to yield is clearly associated with the stop sign, making it the most direct indicator of the need to yield at that location.
