What is the speed range on highways?
3 Answers
Speed should be between 60-120km/h, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not falling below 60 kilometers per hour. On highways, the maximum speed for small passenger vehicles should not exceed 120 kilometers per hour, while other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour. Below are specific details about highways: 1. Design speeds are 80 km/h, 100 km/h, 120 km/h, and 60 km/h (for special sections); 2. The road scale consists of at least four lanes in both directions or at least two lanes in one direction; 3. Highways are classified based on technical grade, ranking above first-class, second-class, third-class, fourth-class, and substandard roads. Highways intersect with national or provincial roads in the hierarchical classification of the road network, meaning highways are part of national or provincial roads within the network.
When driving on the highway, the speed of regular passenger cars generally should not exceed 120 km/h, while larger vehicles like trucks are capped at under 100 km/h. The minimum speed should not drop below 60 km/h, as driving too slowly can easily lead to rear-end collisions. Once, I was driving on the Jingkun Highway in the evening with heavy rain and strong winds, and the speed limit was reduced to 80 km/h. I was driving at 90 km/h and nearly skidded, which gave me quite a scare. Speed adjustments mainly depend on road conditions: 120 km/h on straight roads in clear weather, and reducing speed by 20-40 km/h in curves, tunnels, or rainy conditions is common. A friend reminded me not to rush and risk speeding—getting a ticket costs over 200 yuan, plus points are deducted. Navigation apps can report speed limits in real-time, so I’ve gotten into the habit of setting cruise control at 110 km/h, which is both fuel-efficient and safe. Usually, road signs are clear, and drivers just need to glance at them a few times to avoid accidents.
On highways, the speed limit is generally 120 km/h for cars and 100 km/h for large vehicles, with a minimum safe speed of at least 60 km/h. As someone who frequently drives long distances, I understand these rules are designed to prevent accidents. For example, the braking distance at 120 km/h is nearly double that at 100 km/h, and in rainy conditions, you need even more space. Speed limits vary by section: 120 km/h on plains, 90 km/h in mountainous areas and tunnels, and possibly 80 km/h in construction zones—don't speed recklessly. From personal experience, fuel efficiency is optimal around 110 km/h, and using air conditioning can improve stability. Speed cameras are common, and speeding tickets come with fines and points, while driving too slowly can cause congestion and draw complaints. Remember to use navigation or in-car systems for assistance—arriving safely is a blessing.
