What is the design speed limit for county roads?
2 Answers
County roads generally have a design speed limit of 40 km/h. Below is an introduction to road speed limits: 1. Traffic Safety Law stipulates: Motor vehicles shall not exceed the speed indicated by traffic signs or markings when driving on roads. 2. Roads without center lines: Urban roads have a speed limit of 30 km/h, while highways have a limit of 40 km/h. 3. Roads with only one motor vehicle lane in the same direction: Urban roads have a speed limit of 50 km/h, while highways have a limit of 70 km/h. 4. Township roads: In densely populated areas: The speed limit is 30 km/h. For roads with two lanes in the same direction: The left lane must maintain a speed of no less than 100 km/h.
In China's highway design standards, the design speed for county roads typically ranges between 40 to 60 kilometers per hour, with the specific figure depending on the road grade and terrain conditions. For instance, in mountainous areas or regions with dense curves, the speed may be as low as 40 km/h to reduce accident risks; whereas on straight roads in flat areas, it can reach 60 km/h to enhance traffic efficiency. The design takes into account factors such as low traffic volume and numerous surrounding villages to ensure the safety of pedestrians and cyclists. I remember driving on a mountainous county road where even 40 km/h felt steady—going any faster could cause skidding. These standards are set based on national regulations like the 'Technical Standards for Highway Engineering,' though local adjustments may apply. Drivers should observe road signs to adapt to specific sections, especially driving slower at night for safety and increasing braking distance to prevent accidents.
