When the visibility of fog, rain, snow, etc. is within 50 meters, the maximum speed should not exceed.

According to the Road Traffic Safety Law, "When the visibility of driving a motor vehicle is less than 50m in fog, rain and snow, the speed should not exceed 20km/h". Violators will be fined 200 yuan, with 3 points.

With the change of weather and the influence of climate, when there are bad weather conditions such as fog, rain and snow on the road, drivers need to make corresponding adjustments according to visibility. According to the Road Traffic Safety Law, when a car encounters bad weather conditions with visibility less than 50 meters, it should immediately turn on front and rear lights, fog lights and other lighting equipment and slow down. If the speed exceeds 20 km/h, it is illegal. In addition, according to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China", the maximum speed should not exceed 60 km/h when the visibility is lower than 100 m, and the speed should not exceed 20 km/h when the visibility is lower than 50 m. These regulations are aimed at ensuring the personal safety of drivers and pedestrians, and also have the function of regulating driving behavior. It is worth noting that road traffic accidents often occur in weather conditions with poor visibility. Drivers should be highly vigilant when driving, pay attention to the road surface and surrounding environment, and ensure safe travel.

If traffic accidents are caused by bad weather conditions such as fog, rain and snow, how to determine the responsibility? If the traffic accident is caused by bad weather conditions such as fog, rain and snow, then the responsibility is usually determined according to the specific circumstances of the accident. According to the Road Traffic Safety Law of the People's Republic of China, the responsibility for road traffic accidents shall be borne by the party that caused the accident and shall bear the corresponding liability for compensation. However, in bad weather conditions, the actor may not be able to fully grasp the driving conditions of the vehicle, so the responsibility determination may be adjusted. Generally speaking, drivers should take special measures to prevent bad weather conditions such as rain, fog and snow from affecting driving, and should reasonably adjust the speed and keep a safe distance to reduce the probability of accidents.

Under bad weather conditions, drivers should pay special attention to driving safety, adjust the speed reasonably and keep a safe distance. At the same time, in case of bad weather, turn on the front and rear lights, fog lights and other lighting equipment to ensure the safe travel of yourself and others. If you violate the relevant traffic laws and regulations, you will face penalties such as fines and points deduction.
