The speed on icy and snowy roads should not exceed 30 kilometers per hour. Here is the relevant information: Note: Be aware that the braking distance of the vehicle will be extended. Icy and snowy roads are different from normal roads, as they reduce the friction of the vehicle tires and decrease traction. When driving on icy and snowy roads, it is essential to make early judgments and leave sufficient braking distance in advance. Automobile: According to the latest national standard in China, "Terms and Definitions of Automobiles and Trailers," an automobile is defined as follows: A vehicle powered by an engine, with four or more wheels, not running on tracks, mainly used for: transporting people and/or goods; towing vehicles that carry people and/or goods; or for special purposes.

I've been driving for many years, especially in northern winters where icy and snowy roads are common. You absolutely must not drive fast; I recommend keeping it under 30 km/h. Traction is poor on ice and snow, and even slight acceleration or braking can cause skidding and accidents. I remember once driving at 40 km/h and almost hitting a guardrail—since then, I always stay between 20-30 km/h. It also depends on the conditions; if there's fresh snow, severe ice, or low visibility, you need to slow down even more. Driving slowly and steadily is the safest approach. Regular all-season tires are usually fine, but if you're using performance tires, be extra cautious, as worn tires increase the risk of skidding. One more tip: regularly checking your braking system and switching to winter tires can make a big difference. Safety always comes first—don't rush, because if something happens, regret won't help.

I've pondered many driving safety issues, and keeping speed between 30 to 50 km/h on icy roads is crucial. This isn't a rigid rule—it depends on road slipperiness and vehicle type. For example, SUVs with higher centers of gravity are prone to rollovers, making even 50 km/h potentially dangerous. Urban roads are best kept under 25 km/h, while highways shouldn't exceed 45 km/h. Remember, ABS systems can help in such conditions, but they're ineffective at excessive speeds. Visibility also plays a role; slower speeds are necessary in snowy or foggy conditions with poor sightlines. I recommend practicing low-speed control techniques, like using gentle braking instead of sudden stops. Regular tire maintenance is vital too—worn tires lose traction easily on ice. Ultimately, experience shows that reduced speed is fundamental to accident prevention.

When I first got my driver's license, I drove too fast on icy roads and ended up sliding off the road during a turn, which scared me to death. Now I understand that on such roads, it's best not to exceed 25 to 30 kilometers per hour. Driving school taught me to halve the normal speed and maintain a greater distance from the car in front. Tires are crucial—using regular tires on snow can easily cause skidding, and at higher speeds, the braking distance increases. I also learned to leave half an hour early when going out in the snow, choose low-speed routes, and try to drive at a constant speed without sudden acceleration. There are many accidents in snowy and icy weather, so keeping the speed within a safe range is the most worry-free. Beginners should practice on short stretches to gain experience.

From a traffic regulation perspective, there is no fixed speed limit number for icy or snowy roads, but official guidelines emphasize reducing speed to half or even lower than normal. For example, if you usually drive at 60 km/h, you should drive at 30 km/h. Laws vary by region, with some areas requiring speeds not to exceed 40 km/h during rain or snow. The key is to assess road conditions—if the snow is thick or there is significant ice, you should slow down to below 20 km/h to avoid rear-end collisions or lane departures. Vehicle factors also matter; small cars with weaker traction should maintain a more conservative speed. It is advisable to check local weather warnings and install snow chains in advance. The core of safe driving is to proceed slowly and steadily, avoiding the risk of rushing.
