The following distance is related to vehicle speed, visibility, and road conditions. Generally, when visibility is less than 500 meters but greater than 200 meters, the speed should not exceed 80 km/h, and the following distance should be more than 150 meters. When visibility is less than 200 meters but greater than 100 meters, the speed should not exceed 60 km/h, and the following distance should be more than 100 meters. When visibility is less than 100 meters but greater than 50 meters, the speed should not exceed 40 km/h, and the following distance should be more than 50 meters. Below is a detailed introduction to methods for judging vehicle distance: 1. Using the rearview mirror to judge the distance to the following vehicle: Based on the physical principle that objects appear smaller with distance, when the image of the following vehicle occupies one-third of the rearview mirror, the distance should be 12 meters. When the image occupies half of the rearview mirror, the distance is 9 meters. When the image occupies the entire rearview mirror, the distance is 3 meters. 2. Judging the distance to the vehicle ahead during urban driving: When the rear bumper of the vehicle ahead is visible from the driver's seat, the distance is approximately 1 meter. When the lower edge of the bumper is visible, the distance is about 2 meters. When the rear tires of the vehicle ahead are visible, the distance is approximately 3 meters.
