[LeRiley]

The maximum speed limit on urban roads with center lines cannot exceed 40 kilometers per hour. The speed of motor vehicles on the road must not exceed the speed indicated by speed limit signs or markings. Other speed limit regulations: Roads without center lines: For roads without center lines, the speed limit is 30 kilometers per hour for urban roads and 40 kilometers per hour for highways. For roads with only one lane in each direction, the speed limit is 50 kilometers per hour for urban roads and 70 kilometers per hour for highways. Urban roads include ordinary city roads and expressways, with the former generally limited to 40-60 kilometers per hour, while expressways may have a maximum speed limit of 80 kilometers per hour. Tunnels and ETC lanes: Tunnels and tunnel groups generally have a speed limit of 80 kilometers per hour. Accident-prone sections usually have a speed limit 20 kilometers per hour 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 kilometers per hour, while truck weigh-in-motion lanes have a speed limit of 5 kilometers per hour.
