If a driver at a four-way stop arrives simultaneously with you, what should you do?

At a four-way stop, when two or more vehicles arrive at the same time, the general rule is that drivers should yield to the vehicle on their right. This ensures a clear and fair flow of traffic, preventing confusion and potential accidents at intersections where visibility might be limited. By yielding to the driver on your right, you are following the established traffic laws and promoting safety for all road users.

The other options suggest improper actions that could lead to misunderstandings or dangerous situations. Yielding to the driver on your left ignores the established rules of priority and could cause conflict. Choosing to go first simply because of having a larger vehicle does not adhere to traffic regulations, which prioritize right-hand yielding over vehicle size. Additionally, both proceeding at the same time could lead to a collision if both drivers misjudge the situation. Thus, yielding to the driver on your right is the most appropriate and safest response at a four-way stop when arriving simultaneously.
