What is the minimum speed limit on highways during rainy days?

During heavy rain on highways, the speed can be lower than 60 km/h, subject to the weather conditions and speed limit information issued by the highway management authorities. When driving on highways under low-visibility weather conditions such as fog, rain, snow, dust, or hail, motor vehicles must comply with the following regulations: 1. When visibility is less than 200 meters: Turn on fog lights, low beams, outline markers, and front and rear position lights. The speed must not exceed 60 km/h, and maintain a distance of more than 100 meters from the vehicle ahead in the same lane. 2. When visibility is less than 100 meters: Turn on fog lights, low beams, outline markers, front and rear position lights, and hazard warning flashers. The speed must not exceed 40 km/h, and maintain a distance of more than 50 meters from the vehicle ahead in the same lane.
Driving is something I do every day, especially on highways during rainy days, and the minimum speed really can't be generalized. Under normal weather conditions, the minimum speed on highways is around 60 km/h, but it's different when it rains. Light rain might allow for around 50 km/h, but heavy rain or downpours require reducing speed to below 40 km/h to stay safe. Wet roads reduce tire grip, and driving too fast can easily lead to skidding or losing control. Once, I was driving at 65 km/h in the rain and almost veered off the lane. It's best to adjust speed according to the rainfall and increase the following distance—never gamble with your life to save time. Safety always comes first; slow is fast. Oh, and be extra careful of black ice in winter.
I often drive long distances and find rainy day driving quite critical. Theoretically, the minimum speed on highways is 60km/h, but in rainy conditions, I prefer to reduce it to around 50km/h, or even 40km/h when the rain is too heavy. Tire wear and poor visibility both increase risks, and I clearly feel the brakes are more effective when driving slower. For beginners, it's advisable to maintain a safe speed and not pursue speed too much. Remember to use the defogging function to prevent window fogging, which is crucial for controlling speed. Be extra cautious with sleet during cold weather.
