Which distance is not included in the stopping distance?

[MacNoah]

Stopping sight distance does not include the starting distance. Stopping sight distance refers to the shortest travel distance required for a vehicle to brake and stop when encountering an obstacle ahead on the same lane. The stopping sight distance can be broken down into three parts for study: reaction distance, braking distance, and safety distance. Relevant information about safe following distance is as follows: 1. Introduction: Safe following distance refers to the necessary gap distance that a following vehicle maintains with the vehicle in front to avoid accidental collisions while driving. Maintaining a safe following distance is the most direct, effective, widespread, and fundamental method to prevent rear-end collisions. 2. Measurement standard: There is no absolute standard for safe following distance, only dynamic standards. The most direct and important factor affecting safe following distance is vehicle speed. When the speed increases, the required braking force, braking distance, and the distance traveled at the original speed during the reaction time all increase accordingly.
