What is the minimum speed limit for cars in expressway?

The minimum speed limit of cars in expressway is not less than 60km per hour (except in special circumstances, such as bad weather and traffic accidents).

Article 78 of the Regulations for the Implementation of the Road Traffic Safety Law

Expressway shall indicate the lane speed, with the maximum speed not exceeding 120km and the minimum speed not less than 60km. The maximum speed of minibus driving on expressway shall not exceed 120km, and other motor vehicles shall not exceed 100km.

If there are two lanes in the same direction, the minimum speed of the left lane is100km; If there are more than three lanes in the same direction, the minimum speed of the leftmost lane is110km, and the minimum speed of the middle lane is 90km. If the speed indicated by the road speed limit sign is inconsistent with the lane speed mentioned above, drive at the speed indicated by the road speed limit sign.

Expressway is a high-grade highway. According to the Technical Standard for Highway Engineering of China's Ministry of Communications, expressway refers to a highway that can adapt to the annual average day and night passenger car traffic of more than 25,000 vehicles and is designed for cars to drive at high speed in a single lane, and all entrances and exits are controlled. Although countries have different names for expressway, they all refer to expressway with four lanes or more, two-way separation, complete control of entrances and exits, and all three-way intersections. In addition, many countries use interchanges on some but not all direct trunk lines, which are also called expressway.

Generally speaking, expressway can adapt to the speed above 120km/h (generally 120km/h), and the pavement has a width of four lanes or more. There is an isolation belt in the middle, using asphalt concrete or cement concrete advanced pavement, with complete signs, markings, signals and lighting devices; Pedestrians and non-motor vehicles are prohibited from walking on the road, and other lines are crossed by interchanges, footbridges, bridges or tunnels.

As can be seen from the definition, generally speaking, expressway should meet the following four conditions:

(1) is only used for high-speed driving;

(2) Set up a multi-lane central isolation belt to completely isolate the round-trip traffic;

(3) there is a three-dimensional intersection;

(4) The whole line is closed and the entrances and exits are controlled. At some designated intersections, only cars are allowed to enter and leave the expressway.
