Highway speed limit introduction is as follows: 1. Highways should indicate the driving speed of lanes, the maximum speed should not exceed 120 kilometers per hour, and the minimum speed should not be less than 60 kilometers per hour; 2. The maximum speed of small passenger cars should not exceed 120 kilometers per hour, other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour; 3. If there are 2 lanes in the same direction, the minimum speed of the left lane is 100 kilometers per hour. If there are 3 or more lanes in the same direction, the minimum speed of the leftmost lane is 110 kilometers per hour, and the minimum speed of the middle lane is 90 kilometers per hour. If there is a speed limit sign, the speed should be driven according to the speed indicated by the speed limit sign. In addition, when driving on the highway, when the speed exceeds 100 kilometers per hour, the distance from the vehicle in front in the same lane should be more than 100 meters. When the speed is less than 100 kilometers per hour, the distance from the vehicle in front in the same lane can be appropriately shortened, but the minimum distance should not be less than 50 meters. According to driving experience, the speed and safe distance should be proportional. For example, at 120 kilometers per hour, the distance should be 120 meters, and at 80 kilometers per hour, the distance should be 80 meters, and so on, but the minimum distance should not be less than 50 meters.

Hey, every time I see a 120 speed limit sign on the highway, I pay attention to the minimum speed issue. On highways in our country, the minimum speed must not be lower than 60 km/h in sections with a 120 speed limit. This regulation is mainly to prevent some vehicles from driving at a snail's pace, which could affect the safety of the overall traffic flow. I once encountered a particularly slow-moving van while driving at night and almost rear-ended it, which gave me a real scare. I recommend maintaining a speed between 80-100 km/h during normal driving—it's the safest, neither speeding nor holding up traffic. Be even more flexible in adjusting your speed during special weather conditions; on heavy rain days, I'd rather drive slower than the minimum speed limit.

After driving on highways for so many years, I've noticed that many beginners tend to overlook the minimum speed limit. On a highway with a speed limit of 120, the minimum speed is 60, and this number isn't arbitrarily set. Road design takes into account safe following distances and braking reaction times. Driving below 60 is like placing a moving roadblock on the highway. I've seen some drivers deliberately go at speeds in the 50s to save fuel, only to have trucks behind them honking furiously, creating dangerous situations for the entire lane. In fact, maintaining a speed of around 90 is the most fuel-efficient, as the engine operates within its optimal RPM range, making it more economical than driving slowly.

When I first got my license, my instructor emphasized that the minimum speed of 60 km/h on the highway is just as important as the maximum of 120 km/h. I remember my first time driving on the highway—I saw the 120 sign but foolishly drove at 80 km/h until the navigation warned me for going below the minimum speed limit. The 60 km/h threshold is well set to prevent overly nervous beginners from driving too slowly. Now, on long trips, I use cruise control set at 100 km/h, avoiding speeding while staying clear of slow-moving vehicles. It's worth noting that being caught driving below the minimum speed limit can result in a ticket, with penalties similar to those for speeding.

Recently while helping a friend look for a used SUV, I also researched speed regulations. On highways marked with a 120 km/h limit, traffic laws explicitly require a minimum speed of 60 km/h. This setting is quite scientific, as accident rates skyrocket when speed differentials exceed 30 km/h. The electronic signs on the highway I frequently drive on often display 'No crawling allowed,' and traffic police are more diligent in catching slow-moving vehicles than speeding ones. I recommend that owners with poor vehicle conditions check tire pressure and brakes before entering the highway, to avoid being forced into slow driving due to vehicle issues.

As a veteran driver with twenty years of experience, I must say the safety significance of minimum speed limits is often underestimated. Driving at 40 km/h on a road with a 120 km/h speed limit is just as dangerous as driving at 160 km/h. Once, I saw a stalled car crawling at just over 30 km/h without hazard lights on, causing five vehicles behind to swerve dangerously, nearly causing a major accident. Maintaining speeds above 60 km/h ensures smooth traffic flow. If you really can't keep up, you should move to the emergency lane. The new traffic regulations have increased penalties for low-speed driving, and driving continuously below the minimum speed for more than three minutes will be flagged by traffic cameras.
