What actions are required at a four-way stop?

At a four-way stop, the correct principle to follow is that the first vehicle to arrive at the intersection has the right of way. This ensures that traffic flows smoothly and safely, minimizing confusion and potential accidents. Drivers approaching the stop should look out for other vehicles and yield to those that arrived before them.

In practice, when multiple vehicles arrive at the same time, the vehicle on the right usually has the right of way, which further helps in determining the order of movement. This system relies on adherence to rules of priority to maintain order at intersections.

The other choices suggest different rules that do not align with established traffic laws. For example, stating that the last vehicle to arrive has the right of way would lead to chaotic situations where drivers might hesitate, unsure of when they can proceed. Similarly, the idea that all vehicles can move at once contradicts the purpose of stopping—ensuring safety and clarity in right-of-way situations. Lastly, stipulating that only the largest vehicle has the right of way disregards the principle of equal consideration based on arrival time. Understanding the right-of-way rules at four-way stops is crucial for safe driving practices.
