What is the minimum speed limit on urban roads?

[LeBradley]

When driving on urban roads, the minimum speed limit for roads without a centerline is 30 kilometers per hour, while the maximum speed on urban roads without speed limit signs or markings is 70 kilometers per hour. Specific limits are determined based on the indication signs or markings of different roads or sections as needed. For urban road driving: roads without a centerline have a speed limit of 30 km/h; roads with only one lane in the same direction have a speed limit of 50 km/h; roads with two lanes in the same direction have a maximum speed of 70 km/h, while closed motorways have a limit of 80 km/h. Exceeding the speed limit by less than 10% results in a warning to the driver without fines or penalty points; exceeding by 10%-20% incurs a fine and 3 penalty points; exceeding by 20%-50% incurs a fine and 6 penalty points; exceeding by 50% or more incurs a fine and 12 penalty points.
