What is the safe following distance in urban areas?

[GarrettDella]

In urban areas, the safe following distance is generally more than 50 meters. Below is relevant information about safe following distance: 1. Introduction: Safe following distance refers to the necessary gap maintained by a trailing vehicle to avoid accidental collision with the vehicle ahead while driving. Maintaining a safe following distance is the most direct, effective, widespread, and fundamental method to prevent rear-end collisions. 2. Reference standards: For high-speed driving (speeds above 100km/h), the safe distance should be over 100 meters; for medium-speed driving (around 50km/h), the safe distance should not be less than 50 meters; for low-speed driving (below 40km/h), the safe distance should not be less than 30 meters.
