What is the maximum speed limit on the highway?

[LeRonan]

The maximum speed limit on the highway should not exceed 120 km/h. Here are some precautions for highway driving: 1. Regarding speed: (1) For novice drivers who feel unsure, it is recommended to maintain a speed between 80100 km/h on the highway, with 90 km/h being ideal. (2) When exiting the highway and entering the ramp, apply the brake twice: first, when seeing the 500-meter exit sign, reduce speed to 6070 km/h; second, when entering the ramp, reduce speed to 40 km/h. 2. Regarding driving and lane changing: (1) Novice drivers on the highway should keep the left turn signal on (do not use hazard lights) and stay in the leftmost lane (the passing lane), ignoring honking or flashing lights from vehicles behind. (2) Generally, lane changing or merging is unnecessary. Other vehicles can only overtake from the right. If encountering a slower vehicle occupying the fast lane, change lanes and overtake from the right.

I've been driving for decades and always pay attention to speed limits on highways. The maximum speed limit on expressways is 120 kilometers per hour, which is based on scientific reasoning. When a vehicle travels at high speeds, the chassis design, tire grip, and air resistance must be balanced. Exceeding 120 not only causes fuel consumption to skyrocket but also extends braking distance—a sudden brake could lead to loss of control. I've driven in the rain; when the road is slippery, the car feels unstable at high speeds. On routes with many curves, driving too fast can cause skidding. The national speed limit is set considering average road conditions and driver reaction times, aiming to balance efficiency and risk. For daily driving, I recommend using cruise control to maintain stability—don’t risk your life just to save a few minutes.

As a father of two, my biggest concern when driving on the highway is speeding. The maximum speed limit of 120 kilometers per hour is not just for show—it's a lifeline. I've studied the data, and the accident rate for speeding is several times higher. For example, increasing the speed to 130 kilometers per hour adds at least 20 meters to the braking distance, making it impossible to react in time to sudden situations on the road. When traveling with kids, I always set a speed limit reminder to avoid the impulse to overtake. In rainy or foggy weather, extra caution is needed—keeping the speed below 100 when visibility is poor is the only reliable approach. Remember, the time saved by speeding is not worth the risk of a family tragedy. Developing the habit of regularly checking tire pressure and brakes can significantly improve overall safety.

I'm someone who loves speeding, but experience has taught me that the highway speed limit of 120 kilometers per hour is quite appropriate. Driving fast is thrilling, but over time it becomes exhausting, and the noise gives me a headache. Maintaining a speed of 120 makes the car much more stable, and I can also enjoy the scenery outside the window. During long-distance driving, speeding not only consumes more fuel but also easily causes engine overheating. I often drive on intercity highways and have seen too many rear-end accidents caused by speed demons, a lesson learned the hard way. I recommend keeping something to prevent drowsiness, like listening to podcasts or chewing gum, to make the journey more comfortable.
