What action should you take at a four-way stop?

At a four-way stop, vehicles approaching the intersection must follow the principle that the first vehicle to arrive at the stop sign has the right of way. This means that if two vehicles arrive at the same time, the one on the right has the right of way. However, if multiple vehicles arrive simultaneously, the order in which they arrived determines who proceeds first. This rule is fundamental to ensuring safety and order at intersections, as it provides a clear guideline for drivers to follow, minimizing confusion and potential accidents.

The other options do not accurately reflect the rules governing right-of-way at a four-way stop. For instance, yielding to the vehicle on your right is only applicable in situations where two vehicles arrive at the same time. Similarly, asserting that the vehicle on the left has the right of way misrepresents the order of precedence at stops. Finally, the notion that all vehicles must stop until directed by a sign does not address the established right-of-way laws specifically designed for four-way stops.
