What is the minimum speed limit on highways with a maximum speed of 120 km/h?

[DiNova]

According to Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law", highways shall indicate the driving speed of lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. More extended information is as follows: 1. Overview: Highways, abbreviated as expressways, refer to roads specifically designed for high-speed vehicle travel. Highways have different regulations in different countries, regions, eras, and academic fields. According to China's "Technical Standards for Highway Engineering", highways are multi-lane roads exclusively for vehicles traveling in separate directions and lanes, with full access control. The average annual daily design traffic volume for highways should be more than 15,000 passenger cars, with a design speed of 80 to 120 kilometers per hour. 2. Others: Countries and regions around the world have their own construction standards for highways, without a unified model; there are differences in highway systems between different countries and regions. Some countries and regions include direct trunk roads with partial access control and non-full interchange sections as part of their highway systems.
