Final answer:
The car on the right has the right of way when two cars arrive at an all-way STOP at the same time.
Step-by-step explanation:
In a situation where two cars arrive at an all-way STOP at the same time, the right of way is usually determined by the vehicle to the right.
This means that the car on the right has the right to proceed first, while the other car must wait until it is safe to proceed.
The purpose of this rule is to ensure a smooth and orderly flow of traffic, preventing any potential collisions.
