What is the following distance when exceeding 100 km/h on the highway?

When exceeding 100 km/h on the highway, the following distance should be more than 100 meters. Relevant information is as follows: 1. Introduction: When a motor vehicle is driving on the highway and the speed exceeds 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 can be appropriately shortened, but the minimum distance should not be less than 50 meters. 2. Note: When driving on the highway under low visibility weather conditions such as fog, rain, snow, dust, or hail, the highway management department should issue speed limits, maintain distance, and other prompt information through displays.
As a veteran driver with decades of experience, I believe that when driving over 100 km/h on highways, maintaining a safe following distance is absolutely crucial. I always follow the two-second rule: I pick a fixed reference point, like a roadside sign, and when the car ahead passes it, I start counting 'one thousand and one, one thousand and two'. If my car reaches that point before I finish counting, I immediately slow down to increase the gap. At such high speeds, the actual distance should be at least 50-60 meters to be safe, because braking reaction time alone takes over half a second, and the actual stopping distance can exceed 20 meters. In rain, snow, or heavy fog, I double that distance for peace of mind. Road accidents often happen in an instant, so leaving enough space is the best way to protect yourself. This method is simple and reliable – once it becomes a habit, driving feels much safer.
The advancement of modern automotive technology has made driving more intelligent. For instance, I frequently use the adaptive cruise control system to maintain distance. However, when manually driving at speeds exceeding 100 km/h on highways, manual control is still preferable. Adhering to the two-second rule is crucial: at speeds of 100-120 km/h, the time interval should be at least two seconds, corresponding to a physical distance of approximately 40-50 meters. Braking distance increases exponentially with speed; even at 100 km/h, it may require over 25 meters to come to a complete stop. Factoring in normal reaction time, conservatively maintaining a distance of at least 50 meters can effectively prevent rear-end collisions. Of course, road conditions such as wet surfaces or sudden braking by the vehicle ahead also play a role. It's advisable to regularly utilize in-car assistance systems to aid in judgment. This combination of traditional and technological approaches maximizes both safety and efficiency.
Safety is paramount on highways. When speeds exceed 100 km/h, maintaining proper following distance is crucial. The two-second rule is practical: select a reference point, observe when the preceding vehicle passes it, then count one to two seconds mentally. If you reach the same point too early, adjust immediately. The minimum distance should be at least 50 meters, doubling in rainy conditions. Maintaining this habit prevents emergency braking accidents, as higher speeds require longer braking distances. Importantly, never neglect vehicle maintenance—aging tires can compromise braking performance. In summary, smooth driving is key.
