Final answer:
The correct action at a four-way stop is for drivers to proceed in the order they arrived, with the first to stop being the first to go. If two vehicles arrive simultaneously, the one on the left yields to the one on the right.
Step-by-step explanation:
At intersections with four-way stops, the correct action for drivers is that the driver who stops first should be allowed to go first. Drivers are required to come to a complete stop at the stop sign and then proceed through the intersection in the order in which they arrived. If two drivers stop at the same time, the driver on the left yields the right-of-way to the driver on the right. Insisting on the right-of-way or just slowing down and proceeding if the roads seem clear can lead to accidents and are not lawful or safe practices at four-way stops.
