When two or more vehicles arrive at a four-way stop intersection at the same time, who has the right-of-way?

Answer: D — The vehicle that arrives first

All options except for D are incorrect because in a four-way stop intersection, the vehicle that arrives first is given the right-of-way. This means that if two or more vehicles arrive at the same time, the vehicle that arrived first should proceed through the intersection first. This is to ensure an orderly flow of traffic and prevent confusion or accidents. Therefore, choices A, B, and C are incorrect as they do not follow the standard right-of-way rules for four-way stops.
