When driving a motor vehicle in foggy, rainy and snowy weather, the visibility shall be within 50 meters, and the maximum speed shall not exceed.

When driving a motor vehicle in foggy, rainy and snowy weather, when the visibility is less than 50m, the maximum speed shall not exceed 30km/h, or15km/h in the case of tractors, battery cars and wheeled mechanical vehicles. ..

When driving on icy roads, you should also pay attention to the following points:

1, don't start too fast, the vehicle should speed up gradually, and the starting speed should not be too fast;

2. When the vehicle is driving, if it wants to accelerate, the owner needs to step on the accelerator lightly, but can't step on it suddenly, and the vehicle is easy to slip;

3. Keep a distance from other vehicles. In case of emergency, don't hesitate to step on the brakes in advance, because the ice and snow road is slippery and may not be able to stop the car;

4. If the owner has the conditions, he can replace snow tires or install snow chains to reduce the chance of vehicle slipping.

Precautions for driving motor vehicles in rainy days:

1, slow down. No matter how narrow the road is, no matter whether the road surface is in good condition or not, you should slow down in rainy days, always pay attention to the distance between the front and rear vehicles and your own vehicles, and be prepared to take various emergency measures in advance. In rainy days, the emergency performance such as low visibility, poor vision and braking distance of vehicles will also be reduced, so it is necessary to slow down in advance and leave enough time and space to deal with the situation to ensure safety;

2. Keep the distance between cars. If the driving vision is blocked in rainy days, keep the distance between cars, observe the distance between cars at any time and increase the safe distance. Especially away from big cars. First, it will block the line of sight; Second, the waterlogged car that the cart can pass may not pass, and the cart is easy to splash water and interfere with the driving of the car;

3. Turn on the fog lights when driving in rainy days. Fog lights on rainy days don't let you see others clearly, but let other drivers notice you. In rainy days, fog lights should be fully used to enhance driving safety, and dangerous warning lights should be turned on when necessary, so that the vehicles behind can always pay attention to the dynamics ahead. Turn on the low beam even if there is no fog light;

4. Pay attention to pedestrians. Because pedestrians are holding umbrellas in the rain and cyclists are wearing ponchos, their vision, hearing and reaction are limited. Sometimes, in order to catch up with time, they will turn sharply, and when vehicles approach, they will often panic and slip, which will make drivers unprepared. In this case, drivers should slow down, avoid patiently, choose a safe place to park when necessary, and never compete with pedestrians and bicycles;

5. The flameout cannot be restarted. In case of rainstorm or heavy rainstorm, some sections will be seriously flooded in a short time. If you have to wade, you should use low gear to pass at a constant speed. If the vehicle stops running, don't try to start it again. Blind starting may lead to engine scrapping. After the vehicle is turned off, you should contact the specialized shop in time. After the maintenance personnel check the vehicle on site and make sure there is no problem, they can start it again.

To sum up, when a motor vehicle is driving on an icy road, the maximum speed should not exceed 30 kilometers per hour. When driving on icy roads, you must walk in a straight line and don't change lanes frequently. When driving on icy roads, the accelerator should be light and keep a constant speed. It is absolutely forbidden to step on the accelerator to accelerate.
