What should a driver do at a four-way stop?

At a four-way stop, the correct action is to yield to the vehicle that arrived first at the intersection. This principle is essential for maintaining safety and order, as it ensures that all drivers are aware of who has the right of way based on their arrival time. The rule helps reduce confusion and potential accidents by establishing a clear guideline for which vehicle should proceed first.

In practice, if two cars arrive simultaneously, the vehicle on the right has the right of way. However, if one vehicle has already stopped and is waiting, the other must yield to it, following the fundamental rule of yielding to the first arriving vehicle. This understanding is crucial for drivers to navigate intersections safely and efficiently.
