What are the urban driving speed regulations?

[KiaraRose]

Urban roads have a maximum speed limit of 40 km/h. For roads with only one motor vehicle lane in the same direction, the speed limit is 50 km/h on urban roads and 70 km/h on highways. The specific details are as follows: Speed must not exceed 30 km/h under the following circumstances: When entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, or narrow bridges; when making U-turns, turning, or descending steep slopes; when encountering fog, rain, snow, dust, or hail with visibility less than 50 meters; when driving on icy, snowy, or muddy roads; and when towing a malfunctioning motor vehicle. Speed limit scenarios: Motor vehicles on the road must not exceed the speed indicated by speed limit signs or markings; for roads with two or more motor vehicle lanes in the same direction without speed limit signs or markings, the maximum speed on urban roads is 70 km/h, while the maximum speed on closed motor vehicle-only roads and highways is 80 km/h. Special speed limit situations: Tunnels and tunnel groups generally have a speed limit of 80 km/h; accident-prone sections usually have a speed limit 20 km/h lower than the main highway; sharp curves and interchange ramps are speed-limited according to their design speed; ETC lanes have a speed limit of 20 km/h, and truck weigh-in-motion lanes have a speed limit of 5 km/h.
