Question

Who has the right-of-way at a four-way stop?

Answer 1

the car reaching the intersection and stopping first goes first

Answer 2

If 2 or even more cars reach a 4 stop junction at the same moment, the automobile to the right seems to have the right of way after halting. Red light is flashing - It really should be interpreted as a stop sign; halt and yield to vehicles travelling in the adjoining road.
