Final answer:
At a 4-way stop, when three vehicles arrive simultaneously, the right of way goes to the car on the right. This traffic rule is essential for preventing confusion and maintaining a safe, orderly flow of traffic.
Step-by-step explanation:
When three vehicles reach a 4-way stop at the same time, the right of way belongs to the car on the right. This is a standard traffic rule designed to prevent confusion and accidents at intersections. Applying this rule ensures that drivers have clear guidance on how to proceed safely and courteously, allowing for an orderly flow of traffic. The principle is simple: you yield to the vehicle that is to your immediate right. In a case where the vehicles are directly across from each other, the vehicle going straight would generally have the right of way over the one that is turning.
The 'right-of-way rule' states that when two or more vehicles arrive at a 4-way stop at the same time, the vehicle on the right has the right of way and should proceed first. The vehicles to the left should yield and wait for their turn. If two vehicles across from each other arrive simultaneously, the vehicle going straight has the right of way over the vehicle turning left.
For example, if Car A, Car B, and Car C all reach a 4-way stop simultaneously, Car A will have the right of way over Car B and Car C, Car B will yield to both Car A and Car C, and Car C will yield to Car A and proceed after Car B.
