What is the maximum speed for motor vehicles driving on icy and snowy roads?
2 Answers
Motor vehicles driving on icy and snowy roads have a maximum speed limit of 30 kilometers per hour. The following is relevant information about road traffic regulations: 1. Regulation: Article 46 of the "Implementation Regulations of the Road Traffic Safety Law" stipulates that when driving on icy or muddy roads, the maximum speed of motor vehicles shall not exceed 30 kilometers per hour. 2. Hazards of speeding: When speeding, drivers cannot fully and accurately perceive changes inside and outside the vehicle. For example, when a car is traveling at 50 kilometers per hour, it advances 1.39 meters in 0.1 seconds, with objects outside the window passing by in a flash. However, it takes 0.4 seconds for a person to sense a target within their field of vision and an average of 1 second to clearly see an object. If the speed is too high, it becomes impossible to obtain sufficient road information, increasing the risk of traffic accidents.
I still remember driving on icy roads when I was younger, where the top speed rarely exceeded 30 km/h. The road conditions were terrible back then, and vehicles lacked anti-skid systems, making it easy to slip if you went too fast. Once, I was driving at 25 km/h on a frozen slope and still nearly slid sideways—fortunately, I managed to steady the steering wheel. Nowadays, the recommendations are even stricter, with many local regulations limiting speeds to 20-30 km/h; in northern mountainous areas, it might be even lower. The key is to adjust according to the snow depth, avoid sudden braking or acceleration, and double the following distance. In bad weather, it’s best to check maps or apps for real-time road conditions—safety first saves trouble later. Driving slowly not only saves lives but also lets you enjoy the snowy scenery outside the window.
