Driving a motor vehicle in fog, rain, snow and other visibility within 50 meters, the maximum speed can not exceed how much.

When the visibility of driving a motor vehicle is less than 50 meters in foggy, rainy and snowy weather, the maximum speed shall not exceed 60 kilometers per hour.

The Regulations for the Implementation of the Law of the People's Republic of China on Road Traffic Safety stipulates that when a motor vehicle encounters meteorological conditions such as fog, rain, snow, hail, dust and other special weather with visibility less than 50 meters, the maximum speed shall not exceed 60 kilometers per hour. If the visibility is less than 20 meters, the motor vehicle should stop and wait for the weather to improve before driving. The purpose of this regulation is to ensure that vehicles do not have traffic accidents under complex road meteorological conditions, and also to ensure the safety of pedestrians and other vehicles. It should be emphasized that this is only the highest speed. In fact, in the case of low visibility, drivers should try to slow down and turn on lighting equipment such as fog lights and low beam lights to adapt to complex road meteorological conditions.

In the case of low visibility, if the driver causes a traffic accident because of speeding and other behaviors, how to determine the responsibility? According to the Road Traffic Safety Law of the People's Republic of China, motor vehicle drivers should slow down and turn on lighting equipment such as fog lights and low beam lights when encountering complex meteorological conditions. If a traffic accident occurs because of speeding and other illegal acts, the driver needs to bear the corresponding legal responsibility. If the driver takes necessary measures but a traffic accident occurs, the responsibility will be comprehensively judged according to the specific situation.

In the case of low visibility, drivers need to strictly abide by road traffic safety laws and regulations, slow down as much as possible, do not exceed the speed limit of 60 kilometers per hour, turn on lighting equipment such as fog lights and low beam lights, observe the road ahead, and ensure the safety of themselves and others. At the same time, drivers need to improve their safety awareness, drive in a civilized manner, plan their driving routes reasonably, avoid driving for a long time in bad weather conditions, and prevent traffic accidents.
