How to Judge the Distance Between Vehicles?
2 Answers
Methods to judge the distance between vehicles include: 1. Judging the distance of the rear vehicle through the left rearview mirror; 2. Judging the distance from the front vehicle through the rear of the front vehicle; 3. Identifying the position where the left and right wheels press the line. The distance between vehicles refers to the necessary interval distance maintained by the rear vehicle to avoid accidental collisions with the front vehicle while driving. Maintaining a safe distance is a direct and effective method to prevent rear-end collisions. Measures to maintain a safe distance include: 1. Controlling speed, avoiding traffic flow, and changing lanes to overtake; 2. Referring to road markings, the dotted lines of the high-speed lane dividers are 6 meters long each, with a distance of 9 meters between the lines, totaling 21 meters for two white lines plus the distance in between.
Judging the distance between cars is something I've relied on my intuition and experience for after driving for so many years. The simplest method is the speed rule: maintain a distance of at least two to three seconds from the car in front based on your speed in kilometers per hour. For example, if you're driving at 60 km/h, when the car ahead passes a streetlight or a marker, I count in my head '1001, 1002.' If I finish counting before reaching that point, it's safe; if I don't finish, it means I'm too close and need to brake. Double the time in bad weather. Additionally, using roadside references like utility poles or billboards, when the car ahead passes one, I keep a distance of two or three poles apart. With practice, you'll develop an intuition—just remember not to get too close to prevent rear-end collisions. Beginners are advised to practice in an open area.
