Driving in winter may have such an experience
The road ahead looks no different from usual
But I was a little careless when driving
Vehicles can easily slip or even get out of control
Be careful! Be careful! Be careful!
This is most likely a "dark ice" section
Dark ice section, pay attention to driving!
Dark ice mainly refers to the part of the road with a large water content after rain or snow melting, due to the low external temperature, the water contained in it freezes, the volume becomes larger, the thin ice layer formed by the overflow road surface, the surface is wet and has water marks, smooth and transparent, so that the road surface slip resistance is significantly reduced in winter.
Vehicles on the highway are fast
When encountering dark ice, the safety hazard is even greater
Drivers who lack driving experience in snow and ice
Be aware of such "hidden" dangers
Dark ice due to smooth transparent
Usually on sections of the road with high air humidity
Especially in areas where the temperature difference between day and night is obvious
Pay attention to the road sections
Bridge decks, culvert sections
After the snowfall, the temperature is relatively high during the day, the bridge or culvert are ventilated, and at night, a thin layer of dark ice will appear on the bridge.
Uphill sections
Due to the long time of sunlight on the slopes, the snow can easily melt, and after the sun sets, a thin layer of ice will form on the road surface.
Tunnel entrances and exits
If both ends of the tunnel through which you pass are bridge decks, or if the temperature difference between the inside and outside of the tunnel is large, dark ice is prone to appear at the entrance and exit.
Thus
If you have "after midnight" and "the temperature is close to zero"
"Waterfront cliff bridge section" and other conditions
Dark ice is very prone to surfaces
If there is fog in the air at this time
Safe passage is a top priority
01
Start slowly, drive slowly
When driving on a section with dark ice, start by slowly pressing the throttle, maintaining a uniform speed, and never slamming on the accelerator. Due to the small resistance of the icy road, do not get too close to the car, you need to maintain the usual distance of 1.5-3 times with the vehicle in front, when you need to accelerate or decelerate, the throttle should be slowly stepped down or released to prevent the driving wheel from slipping due to sudden acceleration or deceleration.
02
Slow down early and don't brake urgently
Due to the reduced friction coefficient of the icy road surface, the sharp braking will put the vehicle in an unstable state, causing dangerous situations such as increased braking distance, skidding and even overturning. If it is not clear whether there is a dark ice section in front of you, please reduce the speed in advance, and at the same time brake, do not rush to brake.
03
Slow steering to avoid the vehicle getting out of control
When turning on the icy road, the driver needs to reduce the speed to a safe range before entering the corner, slowly turn in the direction, and do not suddenly accelerate or sharply step on the brakes in the corner, otherwise the vehicle is easy to slip out of control.
04
Note the slope section
When the road is icy, it is more dangerous to drive on the ramp. In particular, it should be avoided to stop in the slope to avoid difficulty in starting due to skidding; when going downhill, the speed should also be slowed down to avoid vehicle skidding.
