Generally, the maximum speed limit on highways is 120 kilometers per hour. Below is relevant information about highway speed limits: 1. Speed limit regulations: When driving normally on highways, the minimum speed for motor vehicles should not be less than 60 kilometers per hour. The maximum speed for small passenger vehicles should not exceed 120 kilometers per hour; for large passenger vehicles, freight trucks, and motorcycles, it should not exceed 90 kilometers per hour. However, if the speed indicated by speed limit traffic signs or road markings differs from the above regulations, the signs or markings should be followed. 2. Different lane regulations: For highways with two lanes in the same direction, the minimum speed for the left lane is 100 kilometers per hour; for highways with three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 kilometers per hour, and the minimum speed for the middle lane is 90 kilometers per hour. If the speed indicated by road speed limit signs differs from the above lane speed regulations, the speed indicated by the road speed limit signs should be followed.

When driving normally on the highway, I think a speed between 100 to 120 kilometers per hour is generally appropriate, especially on China's highways where most sections have speed limits within this range. Every time I drive on the highway, I tend to maintain around 110 km/h, as this keeps pace with the mainstream traffic without causing delays to others, while also avoiding speeding tickets. At 110 km/h, the car runs smoothly and fuel-efficiently, with the engine operating smoothly and fuel consumption kept at a reasonable level. In heavy traffic or rainy conditions, I reduce my speed to 80-90 km/h to ensure sufficient braking distance, as safety is always the top priority. Speeds much higher than 130 km/h increase wind noise, which can distract the driver, while speeds below 80 km/h may lead to being tailgated by other vehicles, causing traffic disruptions. New drivers can start at 100 km/h and gradually adjust as they gain experience. In short, speed should be flexibly adjusted based on road and weather conditions.

As a safety-conscious veteran driver, I recommend maintaining a speed between 90 to 110 km/h during normal highway driving, which strikes a balance between efficiency and risk. Speeds exceeding 120 km/h drastically increase accident rates and double braking distances, making it nearly impossible to react timely to sudden situations ahead. Conversely, driving below 60 km/h can lead to rear-end collisions, which I've personally witnessed on the road. In rainy or foggy conditions, I automatically reduce speed to around 70 km/h and activate fog lights. During long-distance drives, maintaining a safe following distance is crucial—I use the two-second rule to gauge spacing and avoid fatigue. Highways are designed with optimal speeds in mind, and adhering to these rules ensures a safer and more reassuring journey.

For normal highway driving speeds, I consider 110 kilometers per hour to be the sweet spot, offering the most comfortable and efficient performance from the vehicle's perspective. Driving at excessively high speeds, such as 130 km/h, places a heavier burden on the engine, significantly increases fuel consumption, and accelerates tire wear. Conversely, speeds that are too low, like 70 km/h, cause the engine to operate inefficiently, potentially harming the vehicle over time. When driving within the 110-120 km/h range, I find the car responds sharply, handles turns smoothly, and maintains exceptional stability, especially on straight highways, gliding effortlessly. Of course, speeds should be reduced to below 80 km/h at entrances, exits, or curves to prevent loss of control. In heavy traffic, it's best to match the pace of the vehicle ahead rather than accelerating recklessly. For new cars during the break-in period, I recommend driving around 100 km/h to protect the engine. Ultimately, speed management is an integral part of the art of driving.
