What should you do at a four-way stop when two vehicles arrive simultaneously?

At a four-way stop, when two vehicles arrive at the same time, the right-of-way is given to the vehicle on the right. This traffic regulation is critical because it helps to prevent confusion and allows for a clear understanding of who should proceed first. The principle behind this rule is to establish a predictable flow of traffic at intersections where visibility and positioning may be limited.

When drivers know that the vehicle on their right has the right away, they can make informed decisions about when to proceed. This kind of rule relies on the understanding that, as a practical measure, it creates order in traffic situations which might otherwise lead to accidents or further hesitation from drivers trying to figure out who goes next. It is essential for maintaining safety and efficient traffic flow at intersections.

The other choices could lead to misunderstandings. For instance, merely deciding on one's own to go first if turning does not take into account the established traffic laws and could cause accidents. Likewise, stating that the vehicle coming from the left has the right of way contradicts the standard rules of the road. The concept that both vehicles must simply stop and decide can result in indecision and confusion, ultimately jeopardizing the safety of all road users.
