The vehicle on the left must yield to the vehicle on the right when two vehicles arrive at an intersection with 4-way stop signs.
More about 4-way stop signs.
The first vehicle to reach the junction at a 4-way stop has the right-of-way. This regulation always applies when someone has visibly arrived at the stop sign first. The car that is farthest to the right has the right of way when two vehicles pull up side by side to a 4-way stop.
Use of signals is crucial while approaching an intersection head-on with another vehicle. Both vehicles can move forward simultaneously if they are turning or travelling straight.
When two cars arrive at a 4-way intersection simultaneously and one of them wants to turn right while the other wants to turn left, the car heading right has the right of way.
