What determines which car has the right of way at an intersection when vehicles arrive at different times?

The correct answer, which states that the car that arrived at the intersection first has the right of way, is based on standard traffic rules designed to maintain safety and order on the road. When multiple vehicles approach an intersection, the established guideline is that the first vehicle to arrive is entitled to proceed through the intersection without yielding to others. This is crucial in preventing confusion and potential accidents, as it provides a clear rule that drivers can follow when making decisions about who goes first.

This principle is evident in various traffic regulations and helps streamline the flow of traffic, especially in situations where stop signs or signals may not be present. It underscores the importance of awareness and good timing in driving, as those who arrive later must yield to those who have already entered the intersection. By adhering to this rule, drivers can navigate intersections more safely and effectively, reducing the risk of collisions.
