Highway speeding by 10% means 132km/h. Below are three scenarios of highway speed limits: 1. Signage speed limits: These are determined by the speed limits indicated on road signs and markings. This speed classification is not uniformly regulated, and speed limits may vary between different regions or even different sections of the same highway. 2. Statutory speed limits: According to the "Road Traffic Safety Law" and its implementing regulations, on roads without a central dividing line, the speed limit is 40 kilometers per hour; on roads with only one motor vehicle lane in the same direction, the speed limit is 70 kilometers per hour; when entering or exiting non-motorized lanes, passing through railway crossings, sharp curves, narrow roads, narrow bridges, or when making U-turns, turning, or descending steep slopes, the speed limit is 30 kilometers per hour. The maximum speed limit on highways is 120 kilometers per hour. 3. Speed limits during special periods and adverse weather conditions: Passenger vehicles traveling at night (from 10 PM to 5 AM the next day) must not exceed 80% of the daytime speed limit. Additionally, according to the "Road Traffic Safety Law" and its implementing regulations, when driving on ordinary roads in fog, rain, snow, dust, or hail with visibility less than 50 meters, or when driving on icy, snowy, or muddy roads, the speed limit is 30 kilometers per hour.
