What is the standard following distance between vehicles?

[VanKatherine]

When driving on highways, if the speed exceeds 100 kilometers per hour, motor vehicles should maintain a distance of more than 100 meters from the vehicle in front in the same lane. If the speed is below 100 kilometers per hour, the distance can be appropriately shortened, but the minimum distance should not be less than 50 meters. In urban driving, there is no absolute standard for following distance, and it should be judged based on the speed. Additional information about safe following distance is as follows: 1. Definition: Safe following distance refers to the necessary gap that a following vehicle maintains to avoid accidental collisions with the vehicle in front. There is no absolute numerical value for safe distance; it depends on specific circumstances. 2. Theoretical basis: According to the laws of mechanics, a vehicle will continue to move forward for a certain distance during the time it takes to come to a complete stop. If the distance between the vehicle and the one in front is too close, it is very likely to collide with the front vehicle, causing a rear-end accident.
