At a 4-way stop intersection, which vehicle has the right of way if two cars arrive simultaneously?

Answer: B — The car on the right

In a situation where two vehicles arrive simultaneously at a 4-way stop intersection, the vehicle on the right has the right of way. This rule is part of the traffic laws in many jurisdictions and is designed to promote safety and prevent confusion among drivers. By establishing that the driver to the right has the priority, it simplifies decision-making and helps maintain the flow of traffic at intersections. When two drivers meet at a 4-way stop at the same time, it is generally expected that the driver on the right will proceed first. This principle prevents ambiguity and reduces the chances of accidents by providing a clear hierarchy for determining who should move first. Therefore, it's important for drivers to be aware of this guideline and to always remain vigilant, ensuring that they communicate their intentions clearly at such intersections.
