If four cars approach a four-way stop simultaneously, the motorist who arrived first has the right of way and should proceed first. If two or more vehicles arrive simultaneously, the right of way goes to the driver on the right. If a driver stops at a four-way stop but does not have the right of way, they must wait for the vehicle with the right of way to go through the intersection before proceeding.
Drivers must approach four-way stops with caution and be prepared to yield the right of way to other vehicles. Drivers should also use hand signals to indicate their intention to turn and watch for other vehicles and pedestrians in the intersection. These practices can help reduce confusion and improve safety at four-way stops.
