When an intersection does not have any stop or yield signs, the vehicle that arrived first has the right of way, explains DriversEd.com. When two or more vehicles reach the intersection simultaneously, drivers must yield to vehicles on their right.
Sometimes, intersections only have stop signs for drivers heading in one direction, while the cross traffic is under no signaling control, notes DriversEd.com. In this case, the drivers moving in the direction with the signs must remain at a complete stop until all cross traffic clears. Drivers on the through road have the right of way in the case of "T" intersections.
