The speed limit on the Cangshuo Expressway is 100 kilometers per hour. Expressway speed limit regulations: Expressways shall indicate the driving speed of lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not lower than 60 kilometers per hour. On expressways, the maximum speed for small passenger vehicles shall not exceed 120 kilometers per hour, while other motor vehicles shall not exceed 100 kilometers per hour, and motorcycles shall not exceed 80 kilometers per hour. Precautions for driving on expressways: When encountering low visibility weather conditions such as fog, rain, snow, dust, or hail on expressways, and visibility is less than 200 meters, drivers should turn on fog lights, low beam lights, marker lights, and front and rear position lights. The speed should not exceed 60 kilometers per hour, and a distance of more than 100 meters should be maintained from the vehicle in front in the same lane.

As a veteran driver who frequently takes long-distance trips, I've driven on many expressways. The speed limit on the Cangshuo Expressway is generally 120 km/h, which is the standard for most Chinese expressways. However, it's worth noting that in special sections or weather conditions, the limit may drop to 100 km/h, such as during rain or fog. If you're caught speeding by the cameras, you'll be fined 200 yuan and receive penalty points—not worth it at all. Safe driving is the most important thing; maintaining a safe distance and avoiding fatigue driving can also save fuel and peace of mind. I recommend checking a navigation app before setting off, as it provides real-time updates on speed limit changes, helping you avoid surprises. There are plenty of cameras on the expressway, especially near toll stations, so driving a bit slower ensures both safety and savings.

I usually take the highway for business trips, and I guess the speed limit on the Cangshuo Highway is around 120 km/h. Getting caught speeding is terrible—last time I was fined over 300 yuan, which hurt for a while. I recommend using mobile apps like Gaode or Baidu Maps—they’re very accurate and give voice alerts when you exceed the speed limit. Don’t use your phone while driving, and always buckle up. Speed limits vary by section, so pay attention to the signs at the entrance. Slowing down saves trouble and prevents rear-end collisions, which is good for both your wallet and your life.

The primary consideration for speed limits on highways is safety. The baseline speed limit on the Cangshuo Highway is approximately 120 kilometers per hour. In poor weather conditions, it should be reduced to 80 or 100 to prevent skidding accidents. Speeding poses significant risks, increasing the likelihood of losing control, collisions, or rollovers. Adhering to speed limits can extend the lifespan of your vehicle and reduce tire wear. Both novice and experienced drivers should pay attention to prominently displayed speed limit signs and develop good habits to ensure safety.
