What is the minimum speed limit for small cars on highways?

[StRhett]

Car speed limits on highways must not be lower than 60 kilometers per hour (except under special circumstances such as severe weather or traffic accidents). Below are relevant details: 1. Legal provisions: Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law" stipulates that highways shall indicate lane speed limits, with maximum speeds not exceeding 120 kilometers per hour and minimum speeds not lower than 60 kilometers per hour. 2. Highway introduction: Highways belong to high-grade roads. According to China's Ministry of Transport "Technical Standards for Highway Engineering", highways refer to "roads capable of accommodating an average annual daily traffic volume of over 25,000 passenger cars, exclusively designed for high-speed divided-lane vehicle travel with full access control". Although different countries have varying names for highways, they all specifically refer to roads with four or more lanes (inclusive), bidirectional separated traffic, fully controlled access points, and comprehensive grade separation.
