What is the maximum speed limit for highway driving?

[GideonRose]

The maximum speed limit for highways is divided into the following two scenarios: 1. Roads without a central dividing line: The speed limit is 30 kilometers per hour for urban roads and 40 kilometers per hour for highways; 2. Roads with only one motor vehicle lane in the same direction: The speed limit is 50 kilometers per hour for urban roads and 70 kilometers per hour for highways. Additional information: The maximum speed must not exceed 30 kilometers per hour under the following circumstances: 1. When entering or exiting non-motorized vehicle lanes, passing through railway crossings, sharp curves, narrow roads, or narrow bridges; 2. When making U-turns, turning, or descending steep slopes; 3. In conditions of fog, rain, snow, sandstorms, or hail with visibility less than 50 meters; 4. When driving on icy or muddy roads; 5. When towing a malfunctioning motor vehicle.
