What signifies the need for a vehicle to yield at a four-way intersection?

The correct choice indicates that vehicles on a smaller road or street must yield at a four-way intersection. This is based on traffic control rules established to maintain order and safety at intersections. Generally, at intersections where no traffic signals or signs are present, traffic on the larger road has the right of way over traffic on the smaller road. Therefore, vehicles approaching from the smaller road must yield to any traffic on the main road.

This approach is designed to minimize conflicts and accidents, ensuring that vehicles on the more significant thoroughfare can proceed with less disruption, while those on the lesser road await their turn to enter or cross the intersection. Understanding this rule is crucial for safe driving and compliance with traffic laws.
