What should be the safe following distance when driving on highways in snowy conditions?

[Elmer]

In snowy conditions with low visibility, the safe distance should be controlled based on visibility. Specific guidelines are as follows: 1. Visibility less than 50m: When visibility is less than 50m, you should exit the highway. 2. Visibility less than 100m: When visibility is less than 100m, maintain a distance of at least 50m from the vehicle in front. 3. Visibility less than 200m: When visibility is less than 200m, maintain a distance of at least 100m from the vehicle in front. Additional information: Introduction to safe following distance: Safe following distance refers to the necessary gap that a following vehicle maintains with the vehicle ahead to avoid accidental collisions while driving.
