What is the Safe Distance Between Vehicles?

[Barbosa]

The safe distance between vehicles varies depending on the speed: 1. When the speed is above 100 kilometers per hour, the safe distance should be more than 100 meters; 2. When the speed is above 60 kilometers per hour, the safe distance should be numerically equal to the speed, for example, at 60 kilometers per hour, the safe distance should be more than 60 meters; 3. When the speed is 50 kilometers per hour, the safe distance should be more than 50 meters; 4. When the speed is below 40 kilometers per hour, the safe distance should be more than 30 meters; 5. When the speed is below 20 kilometers per hour, the safe distance should be more than 10 meters. The safe distance is the necessary gap that a following vehicle maintains to avoid accidental collisions with the vehicle in front.
