In a city with no priority signs, which vehicle has the right-of-way?

In a situation where there are no priority signs to indicate which vehicle has the right-of-way, the rule typically gives priority to the vehicle on the wider street. This is based on the understanding that wider streets often facilitate more significant and potentially faster traffic flow, which is considered when determining right-of-way in situations where no other signs or signals are present.

Choosing the vehicle on the widest street helps maintain a smooth and safe flow of traffic, reducing the chances of incidents at intersections where vehicles from different streets may converge. It allows for a clearer hierarchy in right-of-way rules to avoid confusion for drivers, especially in urban areas where multiple streets intersect without additional traffic control measures.

The other options do not provide a universally recognized guiding principle. For instance, determining right-of-way based on which street is narrower could lead to conflicts, as it doesn't account for traffic flow or safety considerations. Similarly, speed or the order of arrival could create a chaotic situation, as faster vehicles might not have the required stopping distance to react safely to other vehicles. Hence, the guideline of prioritizing the vehicle on the widest street is essential for ensuring orderly and predictable driving behavior at intersections.
