When driving at speeds exceeding 100 km/h, the minimum following distance should not be less than 50 meters. Article 80 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates: When a motor vehicle is driving on a highway at a speed exceeding 100 km/h, it should maintain a distance of more than 100 meters from the vehicle in front in the same lane; when the speed is below 100 km/h, the distance from the vehicle in front in the same lane can be appropriately reduced, but the minimum distance should not be less than 50 meters. Relevant information about speed limits is as follows: Introduction to speed limits: Speed limits usually refer to the regulation of driving speed within a certain numerical range for a certain length of road. Purpose of speed limits: The main purpose is to pre-warn drivers to reasonably control their speed in subsequent sections of the road ahead, prevent the danger of speeding, and ensure driving safety. Speed limits are an indispensable and most important part of road transport safety.

I've noticed many drivers don't pay attention to maintaining safe distances on highways. Based on my driving experience, when your speed exceeds 100 km/h, you must maintain at least a two-second time gap as your following distance. Simply put, pick a roadside marker like a billboard, start counting 'one thousand one, one thousand two' when the car ahead passes it. If you pass that point before finishing the count, you're following too closely. Converted to actual distance, at 100 km/h this is about 55 meters - the higher your speed, the longer the distance should be. For example, at 120 km/h it should be around 66 meters. On wet roads or at night, double this distance as it helps prevent rear-end collisions. I've personally witnessed disastrous highway accidents caused by insufficient braking distance due to tailgating. Once you develop this habit, you'll feel more relaxed and avoid fatigued driving.

As a driving instructor who frequently teaches beginners, I emphasize the importance of maintaining a safe following distance at high speeds. When your speed exceeds 100 km/h, adhering to the two-second rule is crucial. The specific method involves using roadside reference points to time: start counting silently when the car ahead passes point A, ensuring you reach point A only after two seconds. The standard distance should be no less than half of your speed value—for example, approximately 50 meters at 100 km/h, increasing to 60 meters at 120 km/h. In rainy or foggy conditions, the distance should extend to over 100 meters. Relevant factors include vehicle weight (small cars differ from large trucks) and driver reaction time, which averages 0.5 seconds. I recommend testing your habits right at the highway entrance; developing this practice can significantly reduce accident rates. Remember to avoid distractions like checking your phone—safety always comes first.

As someone who commutes on the highway every day, I believe maintaining a safe following distance is crucial. When driving over 100 km/h, I usually keep about 60 meters of distance to handle emergencies. The basic method is using the three-second rule: pick a fixed point ahead, and count if I reach it within three seconds after the car in front passes, ensuring enough buffer. The faster the speed, the greater the danger—at 100 km/h, braking distance can exceed 40 meters, plus reaction time, so never go below this range. In poor road conditions, extend it further for extra precaution. Here’s a tip: navigation apps often remind you to stay safe; adjusting accordingly helps avoid fines and collision risks. Simple and practical—it could save your life.
