After a snowfall
The chill is also gradually invading
I'm sure you may have such an experience
The road ahead looks the same as usual
But you don't pay attention when driving
Vehicles can easily slip and even lose control
Be careful! Be careful!
This is most likely the "dark ice" section
▼
Dark ice sections, drive carefully!
Dark ice mainly refers to the part of the road with a large water content after the rainfall or snowfall melts, due to the low outside temperature, the water contained in it freezes, the volume becomes larger, and the thin ice layer formed by the overflow road surface, the surface is moist and has water traces, smooth and transparent, so that the slip resistance of the road surface is significantly reduced.
The speed of vehicles on urban expressways and highways is fast
When dark ice is encountered, the safety hazard is even greater
Drivers who lack experience driving in snow and ice
It is important to be aware of such "hidden" dangers
Pay attention to the road segments
Bridge decks, culvert sections
After the snowfall, the temperature is relatively high during the day, and the bridge or culvert is ventilated, and at night a thin layer of dark ice appears on the bridge.
Pay attention to the road segments
Uphill sections
Due to the long hours of sunlight on the slopes, the snow melts easily, and a thin layer of ice forms on the road surface after the sun sets.
Pay attention to the road segments
Tunnel entrances and exits
If there is a bridge deck at both ends of the tunnel, or if the temperature difference between the inside and outside of the tunnel is large, dark ice is prone to appear at the entrance.
In case of rain or snow on the road
Be sure to "slow down, control distance, and brighten the tail"
In case of unforeseen circumstances
Please evacuate in time and report to the police
