Final answer:
No person operating a vehicle should follow another vehicle closer than a specific distance, typically around 3 seconds of separation.
Step-by-step explanation:
The answer to the question is that no person operating a vehicle should follow another vehicle closer than a specific distance, which is usually determined by local laws and regulations. In the United States, for example, the typical minimum following distance is around 3 seconds of separation.
This means that a driver should maintain a distance that takes them at least 3 seconds to reach the same point as the vehicle in front of them. This following distance allows for enough time to react to any sudden changes in the road conditions or the actions of the vehicle ahead.
