What are the speed limits on various roads?

The types and speeds of speed limits on various roads are as follows: Posted speed limits: These are the speeds indicated by speed limit signs and markings on the road. The specific speed limit values are determined by transportation authorities based on factors such as the road's design speed, functional type, geometric alignment characteristics, traffic flow, and roadside environment. Statutory speed limits: On roads without speed limit signs, the limits prescribed by laws and regulations must be followed. According to the "Road Traffic Safety Law" and its implementing regulations, the speed limit on roads without a centerline is 40 kilometers per hour. On roads with only one 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. Speed limits during special periods and weather conditions: 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 on icy, snowy, or muddy roads, the speed limit is 30 kilometers per hour. These measures are strictly enforced to regulate passenger vehicles.
I usually drive my sedan in the city and find that speed limits vary widely. On main urban roads, it's generally 30 to 50 km/h, while sections near schools and hospitals are even lower, dropping to 20 to 30 km/h, as safety comes first. On highways, you can speed up to 100 to 120 km/h, but if you encounter road construction or winding mountain roads, the limit instantly drops below 80 km/h. You need to be extra cautious in rainy or foggy weather—if speed limit signs aren’t clear, you’ll have to rely on instinct to slow down. Once, I was caught speeding by 10% on camera, fined 200 yuan, and had 3 points deducted from my license—a harsh lesson. Now, I use navigation apps for advance warnings and make a habit of watching for changing road signs. Speed limits aren’t just numbers; you also need to adjust flexibly based on weather and road conditions, maintaining a 40-second following distance and avoiding sudden braking. Following them not only avoids fines but, more importantly, protects yourself and other pedestrians.
As a seasoned long-distance driver who frequently travels on national highways and expressways, I've experienced various speed limit scenarios. The main expressway lanes typically have speed limits ranging from 100 to 120 km/h, but these suddenly drop to 60-80 km/h near service area entrances or urban sections. On rural national highways, the limit is usually 40-60 km/h, and during heavy fog or snow, I personally reduce to 30 km/h to prevent skidding. Construction zones impose temporary limits of 30-50 km/h - exceeding these means at least a 200 yuan fine. I've learned that driving isn't just about speed; you must watch for roadside cameras and traffic signs, especially in newly developed areas where widened roads may have stealthily increased limits. The essence of safe driving lies in anticipating road conditions. I recommend drivers regularly check tire pressure and brake systems to ensure smooth deceleration in emergencies. Speed limits aren't constraints but barriers keeping you away from accidents.
