What is the speed range on highways?

[ArcherFitz]

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.
