How to Judge Distance with Rearview Mirrors?

[LeLila]

The method to judge distance using rearview mirrors is: 1. If the rear vehicle occupies one-third of the outer rearview mirror area and the entire vehicle is visible, the distance to the rear vehicle is approximately 15 meters, allowing for turning operations; 2. If the rear vehicle's grille is completely obscured, the distance between the rear vehicle and the front vehicle is 3 meters, which is a safe distance during slow-speed following; 3. When the rear vehicle is positioned in the center of the rearview mirror, it indicates a distance of 15 to 20 meters from the rear vehicle, enabling normal turning operations. Rearview mirrors are tools that allow drivers to directly obtain external information about the rear, sides, and lower parts of the car while seated in the driver's seat. For the convenience of drivers, to prevent traffic safety accidents, and to ensure personal safety, all countries have regulations regarding automobile rearview mirrors.
