When driving on dark frost, dew, icy and snowy roads, the friction coefficient between the wheels and the ground is significantly reduced due to slippage of the road surface, which is likely to cause the vehicle to slip, move laterally and increase the braking distance, expanding the danger zone. Therefore, it is necessary to reduce the vehicle speed and maintain a uniform driving speed. In the case of intersecting vehicles, it is necessary to slow down in advance, choose an appropriate location, pass slowly and smoothly, and overtaking is strictly prohibited. Driving on the outer ring road, especially in the corners, must be extra careful, the driving direction should not be too fast, at the same time to avoid sudden braking and prevent side slipping.

In addition, foggy driving can be guided by the white lane markings on the road surface and the red taillights of the vehicle in front.

1. When the visibility of the highway is less than 500 meters and more than 200 meters, the low beam lights, width lights and tail lights must be turned on; the speed should not exceed 80 kilometers per hour; the driving distance between the front cars driving in the same lane must be more than 150 meters.
2. When the visibility of the highway is less than 200 meters and more than 100 meters, the fog lights, low beam lights, width lights, and tail lights must be turned on; the speed should not exceed 60 kilometers per hour; the driving distance between the front car and the same lane must be more than 100 meters. .
3. When the driving visibility of the highway is less than 100 meters and more than 50 meters, the fog lights, low beam lights, width lights and tail lights must be turned on, and the speed should not exceed 40 kilometers per hour; the driving distance between the front cars driving in the same lane must be more than 50 meters .
4. When the visibility of highway traffic is less than 50 meters, the public security organ may take some or all road sections to close the highway traffic control measures according to the regulations.
