Does the 80 km/h speed limit on highways refer to large vehicles or small cars?

[HarmonyRose]

Highway speed limit of 80 km/h refers to large vehicles. Below is an introduction to highway speed limit regulations: 1. China's highway speed limits for large trucks, buses, and small cars: generally 80 km/h, 100 km/h, and 120 km/h respectively. Vehicles traveling in the same direction on the same lane are required to maintain a minimum distance of 200 meters, ensuring sufficient braking distance to avoid chain collisions if the leading vehicle suddenly stops due to an accident. 2. Speed limits in tunnels and tunnel clusters: generally set at 80 km/h. Accident-prone sections usually have speed limits 20 km/h lower than the main highway. Sharp curves and interchange ramps have speed limits based on their design speed. ETC lanes have a speed limit of 20 km/h, while truck weigh-in-motion lanes have a speed limit of 5 km/h. Additionally, except for ring roads which implement lane-based speed limits, all other sections of the road network enforce speed limits based on vehicle type.
