What are the methods for beginners to judge the distance between cars while driving?
2 Answers
Beginners can judge the distance between cars by the following methods: 1. When the upper edge of the rear bumper of the car in front is visible, the distance is 1m; 2. When the lower edge of the rear bumper of the car in front is visible, the distance is 2m; 3. When the lower edge of the rear tires of the car in front is visible, the distance is 3m; 4. If the car's shadow occupies the entire rearview mirror, the distance is 3 meters; if the shadow occupies two-thirds of the rearview mirror, the distance is 5 meters; if the shadow occupies half of the rearview mirror, the distance is 9 meters; if the shadow occupies one-third of the rearview mirror, the distance is 12 meters. Reasons for maintaining distance: 1. To avoid rear-end collisions caused by sudden braking of the car in front; 2. To reserve reaction time for handling emergencies.
This question is particularly important. I remember when I first started driving, I was always unsure about distances. First, let's talk about judging through the rearview mirror. When the entire front of the car behind you fills your interior rearview mirror, the distance is roughly about 3 meters. At this point, you shouldn't reverse any further, especially in very tight parking spaces where extra caution is needed. Another practical method is to observe the relationship between your car's rear end and the bottom of the rear car's tires. If you can see the ground markings, there's usually about 1.5 to 2 meters of space left. Side distance isn't too difficult either; while driving, pay attention to the lane lines and your car's body position. Keeping the white line near the lower left corner of the windshield generally means you're centered. On the highway, it's best to maintain a following distance where you can see the entire tire of the car in front, and in rainy conditions, you should increase this distance further. The most practical advice is to practice in open areas—place cones in front of and behind your car to get a feel for the distances. After a few tries, you'll develop a better sense of your car's dimensions.
