What is the safe distance between vehicles on urban roads?

[Juniper]

There is no absolute standard for the correct following distance on urban roads according to traffic laws, only dynamic standards. The safe distance between vehicles does not have an absolute standard, only dynamic standards. The most direct and important factor affecting the safe distance is speed. When driving at speeds above 100km/h on highways, the safe distance should be more than 100 meters. Reference speeds: When driving at speeds above 100km/h on highways, the safe distance should be more than 100 meters. When driving at speeds above 60km/h on fast roads, the safe distance in meters should be equal to the speed in km/h. When driving at medium speeds around 50km/h, Three-second interval: At a speed of 36km/h, which is 10 meters per second, the distance covered in three seconds is 30 meters; at a speed of 72km/h, which is 20 meters per second, the distance covered in three seconds is 60 meters; at a speed of 108km/h, which is 30 meters per second, the distance covered in three seconds is 90 meters.
