How to drive at high speed in rain, snow and fog?

Speed limit of expressway in snowy days: when the visibility is less than 200m, the maximum speed is 60 per hour, and the distance above 100m should be maintained. When the visibility is lower than 100 m, the maximum speed is 40 and the distance is more than 50 m. When the visibility is less than 50m, the maximum speed is 20. Leave expressway from the nearest exit as soon as possible.

According to the Regulations for the Implementation of the Road Traffic Safety Law, when driving in heavy rainfall, snowfall and foggy weather and the visibility of road conditions is less than 200m, drivers should turn on fog lights, low beam lights, position lights and front and rear position lights, and the speed should not exceed 60km per hour, and keep a distance of 100m or more from the vehicle in front of the same lane.

When the visibility is less than 100 meters, at this time, in addition to turning on the fog lights, low beam lights, position lights and front and rear taillights, you should also turn on the hazard warning flashing lights (double flashing lights) and ensure that the speed is not higher than 40 kilometers per hour.

Precautions for high-speed driving in snowy days:

1. Fasten your seat belt when driving.

Drivers need to drive carefully. In rainy and snowy days, the road is slippery, so slow down and keep the distance between cars. In the case of vehicles queuing, etc. , should obey the command and guidance of traffic police and auxiliary police, and pass in turn.

2. Keep driving at a low speed

The adhesion coefficient of ice and snow pavement is much lower than that of dry oil pavement. At the same speed, the braking distance on ice and snow roads is many times longer, and the visibility is lower in snowy days. In this case, the speed of motor vehicles should be reduced according to law, and the speed should match the sight distance.

3. Keep a safe distance from the vehicle in front.

It is very important to keep a safe distance when driving on the expressway in snowy days. Because the snowy road is slippery and the braking distance becomes longer, it is not appropriate to take sudden braking to prevent sideslip.

4. Pay attention to the correct use of lighting.

Generally, visibility is low in snowy days, so attention should be paid to the correct use of lights. When visibility is reduced, in addition to turning on the position lights and front and rear position lights, fog lights and low beam lights should also be turned on to help drivers observe the situation ahead and improve their vehicle identification ability.

5. Try to avoid overtaking on icy roads.

When overtaking is necessary, you should choose a spacious, flat road with less ice and snow, and you should not overtake by force. Moreover, never change lanes immediately when overtaking, and try to leave a safe distance for being overtaken.
