The default behavior in the USA, at an intersection where all roads have a stop sign, is one vehicle at a time, in the order in which they reach the actual intersection.  Such an intersection is called a "four-way stop", or an "all-way stop" in cases where there are more or fewer than four ways involved.  The precedence rule is not explicitly signed, but drivers are expected to be aware of it.
