What is the maximum speed limit for driving on icy and snowy roads?

[ElijahDella]

The maximum driving speed should not exceed 30 kilometers per hour. Here is some relevant knowledge about driving in snowy and icy weather: Longer braking distance: Be aware that the vehicle's braking distance will be extended. Icy and snowy roads are different from normal roads as they reduce the friction of the vehicle's tires, and the adhesion will also decrease. When driving on icy and snowy roads, it is essential to make early judgments and leave sufficient braking distance in advance. Switching to snow tires: When driving in winter, it depends on the region. In northeastern areas, it is necessary to switch to snow tires because the temperature is lower there. Using all-season tires on icy and snowy roads can lead to skidding, and in severe cases, the vehicle may not move at all. In southern regions, vehicles rarely switch to snow tires in winter because snowfall is infrequent.

I remember when driving on icy or snowy roads, the speed must be kept very low, definitely not exceeding 30 to 40 kilometers per hour. After all, as a veteran driver who has been driving in the north for years, vehicles tend to skid when there is snow or ice on the road, so even the usual speed should be halved. Once, I drove slightly faster, around 40 km/h, and felt like I was losing control. Fortunately, I slowed down in time to avoid an accident. The reason is simple: icy and snowy roads reduce friction, and the braking distance can be three times longer than on dry roads. If you encounter a sharp turn or an emergency, there's simply no time to react. For safety, I recommend everyone keep their speed below 30 km/h, ensure they have winter tires or snow chains installed, and get their vehicles serviced in advance. Don’t rush—your life is more important. Driving slowly is much safer. I often remind my novice friends not to pick up bad habits like speeding. Driving slowly is the way to get home safely.

As a young driver, I learned the precautions for driving on icy and snowy roads only when I started driving. The maximum speed should not exceed 40 km/h, and it's best to keep it even lower. I'm used to driving fast on highways, but when it snows, I force myself to slow down to 20-30 km/h because the tire grip is too weak, and going slightly faster could cause drifting. I remember during my probationary period, I was driving on an icy section of a highway exit at just 35 km/h and almost scraped the guardrail. Fortunately, I had learned how to operate ABS. New drivers often make the mistake of thinking that driving slowly is enough, but the key is to continuously observe road conditions, such as checking the depth of snow piles or ice layers ahead. It's best to have a thermometer and anti-slip equipment in the car, regularly check the braking system, and develop a habit of driving slowly to avoid major accidents.

From my years of research on automotive safety, the recommended maximum speed on icy and snowy roads should be maintained between 30 to 50 kilometers per hour. The exact speed depends on road conditions - for instance, below 30km/h in deep snow areas, and not exceeding 40km/h on thin ice. The scientific basis is that braking distances increase significantly on icy surfaces; at 40km/h it can exceed 50 meters, compared to just 10 meters on dry roads. Always activate the vehicle's anti-skid system, maintain steady speed, and avoid sudden acceleration or braking to minimize skidding risks. During poor weather conditions, planning routes in advance to reduce driving time is paramount for ensuring travel safety.

As a family person, when driving with my child in snowy or icy conditions, I always keep the speed between 25 to 35 kilometers per hour and never exceed this range. If the car skids at higher speeds, even a child safety seat won't fully protect my child, which could lead to a serious accident. I make sure to check the weather forecast and road conditions beforehand, ensure the vehicle is equipped with proper anti-skid devices, and teach my child to sit quietly without causing distractions. Driving slower also helps reduce motion sickness for my child, killing two birds with one stone. Remember, safety comes first—don't rush by speeding. A smooth and steady drive is key for family trips.

From a technical perspective, the maximum speed on icy and snowy roads should not exceed 40 kilometers per hour. The reason is that the road friction coefficient drops to around 0.1 (normally 0.7), and braking distance exceeds 30 meters when accelerating to 40km/h, making sharp turns highly prone to rollovers. When driving, I recommend utilizing ABS and EBD systems for assistance, while manually controlling the RPM smoothly. Regularly maintain tire pressure, inspect wipers and snow removal devices, drive slowly with steady operations to effectively avoid accident risks. Prioritize main roads in poor conditions, and never overlook the importance of detailed maintenance.
