What is the safe driving distance for a car?
2 Answers
The safe driving distance for a car is: 1. High-speed driving, when the speed is above 100 kilometers per hour, the safe distance should be more than 100 meters; 2. Fast driving, when the speed is above 60 kilometers per hour, the safe distance should be equal to the speed in numerical value; 3. Medium-speed driving, when the speed is around 50 kilometers per hour, the safe distance should not be less than 50 meters; 4. Low-speed driving, when the speed is below 40 kilometers per hour, the safe distance should not be less than 30 meters. Precautions for driving a car include: 1. Avoid overloading; 2. The driver should avoid playing around while driving and stay focused; 3. Shift gears in a timely manner; 4. Do not slam on the brakes during the break-in period of a new car; 5. Do not frequently use emergency braking; 6. Do not occupy two lanes for a long time; 7. When turning or changing lanes, always use the turn signal and reduce speed.
Having driven for over twenty years, I find the concept of safe following distance particularly crucial, especially on highways. The most fundamental rule is the 2-second rule: I pick a fixed reference point, like a road sign or bridge pier, and when the car ahead passes it, I start counting '1001, 1002' silently. If I reach that point only after finishing the count, it's considered a safe distance. The actual distance varies with speed—about 28 meters at 50 km/h and at least 56 meters at 100 km/h. On rainy days or slippery roads, I add an extra second to prevent skidding during braking. I recall a near-miss rear-end collision years ago caused by fatigue-induced distraction and following too closely, leaving no time to brake. Now I've developed a habit of frequently checking the rearview mirror to remind myself, and even in city traffic jams, I avoid tailgating to leave space for emergency reactions. Ultimately, keeping a greater distance doesn’t delay anything; instead, it offers peace of mind and accident prevention, especially during nighttime driving when visibility is poor and extra vigilance is needed.
