What determines the right of way at a four-way stop?

The right of way at a four-way stop is primarily determined by the principle that the first vehicle to arrive at the intersection has the right of way. This rule is designed to facilitate safe and orderly traffic flow, allowing drivers to navigate intersections without confusion or the potential for accidents.

When multiple vehicles arrive at a four-way stop simultaneously, the drivers are expected to communicate and yield to one another as necessary, typically allowing the vehicle on the right to go first if all are arriving at the same time. This helps in situations where it can be unclear which driver should proceed first. However, the main rule remains that the first vehicle to reach the intersection holds the priority to move ahead, emphasizing the importance of attentiveness when approaching such intersections.

The other options do not align with standard traffic rules applicable to four-way stops, as signal lights and vehicle noise do not dictate priority at a stop sign intersection. Understanding this principle is crucial for ensuring safety and compliance with traffic laws.
