How to Judge the Distance Between Vehicles

[MacTravis]

Methods for judging the distance to the vehicle in front are as follows: 1. When the upper edge of the front vehicle's bumper is visible from the lower edge of the windshield, the distance is approximately one meter. 2. When the lower edge of the front vehicle's bumper is visible from the lower edge of the windshield, the distance is approximately two meters. 3. When the lower edge of the front vehicle's rear tire is visible from the lower edge of the windshield, the distance is approximately three meters. 4. The horizontal line relative to the ground seen at the lower edge of the left rearview mirror indicates the position of your own vehicle's front. Methods for judging the distance to the vehicle behind are as follows: 1. When the image of the rear vehicle occupies the entire rearview mirror, the distance is approximately 3 meters. 2. When the image of the rear vehicle occupies two-thirds of the rearview mirror, the distance is approximately 5 meters. 3. When the image of the rear vehicle occupies half of the rearview mirror, the distance is approximately 9 meters. 4. When the image of the rear vehicle occupies one-third of the rearview mirror, the distance is approximately 12 meters.
