Final answer:
When two or more vehicles reach an intersection with no traffic signs or signals at the same time, the vehicle on the right should be given the right of way. This ensures a safe and smooth flow of traffic.
Step-by-step explanation:
The car on the right ought to have the right of way when two or more cars arrive at an intersection simultaneously without any traffic signs or signals. This indicates that the car on the left needs to move over and give way to the car on the right so that it can pass first. To maintain a safe and efficient flow of traffic, it is crucial to drive cautiously and interact with other motorists.
