Final answer:
At a multi-way stop intersection, if two motorists arrive at the same time, the motorist on the right has the right of way, which is a safety measure to manage traffic flow.
Step-by-step explanation:
At a multi-way stop or stop intersection, a motorist must yield to the motorist on the right if both motorists get there at the same time. This rule is applied to ensure the safety and flow of traffic at intersections where the order of precedence is not controlled by traffic lights. It helps prevent confusion and potential accidents by providing a clear guideline on who has the right of way. When approaching such an intersection, it's crucial to be aware of your surroundings and be prepared to yield to drivers on your right if you both arrive simultaneously.
