Final answer:
At "All Way" or "4 Way" intersections, the vehicle on the left must yield to the vehicle on the right when arriving simultaneously.
Step-by-step explanation:
In "All Way" or "4 Way" intersections, when multiple vehicles arrive at the intersection at the same time, the general rule of thumb is that the vehicle on the left must yield to the vehicle on the right. This means that if you are the driver on the left, you should wait and allow the vehicle on your right to go first. The rule is designed to prevent confusion and collisions at intersections and is a basic principle of road safety.
