Generally, the maximum speed is 120km/h, and the driving speed should not be lower than 80km/h. Below is some extended information about highways: 1. Precautions for highway driving: When driving on highways, it is essential to adhere to the speed limits. The driving speed should not be lower than the minimum limit nor exceed the maximum limit. While driving on highways, maintain a sufficient safe distance from the vehicle ahead. As the driving speed increases, the distance from the vehicle ahead should also increase. 2. Use of lights when driving on highways: If driving on highways at night, you can turn on the high beams because highways have central dividers, so using high beams will not affect the visibility of oncoming drivers. If you are close to the vehicle ahead, it is recommended to turn off the high beams.

When driving on the highway, I usually maintain a speed of around 120 km/h, as many sections have a speed limit of 120. This speed is both safe and stable. I notice that during heavy traffic, I reduce my speed to 100-110 km/h to avoid tailgating and potential accidents. Occasionally, when traffic is light, I increase my speed to 130 km/h, but only for a short distance. Staying within this range helps prevent sudden braking or loss of control, especially on rainy days when I never exceed 100 km/h—poor visibility poses too high a risk. Additionally, a car's performance influences speed habits; with my family sedan, I generally stick to this range for fuel efficiency and peace of mind. In short, adhering to speed limits and avoiding the temptation to go faster actually makes for a more relaxed drive.

I believe safe driving is more important than anything else, and it's best not to exceed 120 km/h on the highway. I personally experienced a near-accident due to speeding in the rain, so now I keep my speed steady between 100-110 km/h to ensure enough reaction time. The 120 km/h speed limit is reasonable—any faster and the braking distance more than doubles, and driving fast at night increases fatigue. I advise all drivers to check their speedometers and avoid speeding for thrills, protecting themselves and their families. By the way, driving at a slower speed feels more comfortable, with less road noise and less fatigue on long trips. Strictly adhering to safety rules is the responsible approach.

As a car enthusiast, I often test my car's performance on the highway. Generally, it's no problem to drive between 110 to 140 km/h, but I don't recommend exceeding 130. Regular cars handle stably within this speed range, while sports cars might go even faster, but road conditions should be considered. Remember, taking turns at too high a speed can make the car feel floaty—I've had to brake a few times after trying it. Safety first; know your car's limits before pushing it.

I've noticed that the speed on the highway directly affects fuel consumption. I usually maintain between 90 to 100 km/h for better fuel efficiency. Exceeding 120 km/h causes fuel costs to rise sharply due to increased air resistance, which wastes resources. I also consider environmental protection – driving slower reduces emissions and benefits air quality. A balanced choice is around 110 km/h, which doesn't waste time and is cost-effective. Pay more attention to the speedometer and make it a habit.

Legally, the speed limit on highways is mostly 120 km/h. I never exceed the speed limit while driving, maintaining a steady speed between 100-120 km/h. Speeding will result in a fine of over 200 yuan and penalty points, which is not worth the risk. In some mountainous areas, the speed limit is 100 km/h, so I must pay attention to road signs and adjust accordingly. Following the rules helps avoid unnecessary trouble.
