What is the standard following distance?

[DiEmery]

When driving on highways, if the speed exceeds 100 km/h, the vehicle should maintain a distance of more than 100 meters from the vehicle ahead in the same lane. If the speed is below 100 km/h, the distance can be appropriately reduced, but the minimum distance should not be less than 50 meters. In urban areas, there is no absolute standard for following distance; it should be judged based on the speed. The following distances for urban driving are as follows: 1. If the speed exceeds 60 km/h, the following distance should be equal to the speed in meters. 2. At 50 km/h, the following distance should be at least 50 meters. 3. At 40 km/h, the following distance should be at least 30 meters. 4. At 20 km/h, the following distance should be at least 10 meters.
