How do you make traffic as safe as possible at the technical level?Let's find out.
The roads are icyRefers to the accumulation of snow or ice when precipitation (such as rain, snow, freezing rain or fog droplets) hits ground with a temperature below zero. This typically includes hard ice formed during the cold season by frozen remnant snow, convex and concave ice ruts, snow melt, or other causes of road water. There are generally two types of road icing, one is the formation of road ice that freezes on the road surface immediately after snowfall;The other is the formation of ice on the road surface due to the drop in temperature after the snow melts. The occurrence of icy roads poses a great threat to traffic safety.
Actually, just in the last few days.
Because of rain and snow, the road is slipperyTraffic accidents occurred in many places.

For the public who have travel needs.
Whether on foot, by car, by public transport.

For pedestrians
What should I do if the road is icy?
Recently, in some areas, due to heavy snowfall and plummeting temperatures, the road surface has directly turned into an "ice rink", and the road is slippery and difficult to fall on in cold weather, so keep these points in mind.
Always be vigilant
On snowy days, there are many places outdoors that are slippery and slippery, so you should always be vigilant in such an environment. In particular, many roads are not covered with snow, but there is a thin layer of ice. This condition is the easiest to overlook and the most likely to cause slips.
Wear warm clothing and non-slip shoes
When traveling in snowy weather, wear gloves and warm clothes;The trousers should not be too long to avoid falling when stepping on the hem;Socks fit well, do not wear slippery feet**;The laces should be fastened tightly and the laces should not be too long to avoid falling when stepping on the lacesPick the right non-slip shoes.
Slow down your walking
When traveling on snowy days, it's a good idea to allow more time. Every step must be stepped on, one step at a time, and the "down-to-earth" walk will not slip, especially when encountering uneven roads, and the pace must be slowed down.
AvoidWalk in the dark
On snowy days, the lack of light increases the likelihood of slipping. Therefore, it is necessary to ensure that the travel environment is as well lit as possible, try to avoid traveling in the dark, and carry a flashlight if necessary.
Older people avoid going out
Older people should try to avoid traveling after the snow and try to be accompanied by family members if they need to go out. In addition, assistive devices, such as crutches, can be used depending on the physical condition.
At last. Please pay attention to the weather forecast and warning information.
Facing the icy road.
Take preventive measures in a timely manner.
