When the visibility of fog, rain, snow, etc. is within 50 meters, the maximum speed should not exceed.
This regulation is to ensure road traffic safety under bad weather conditions with low visibility. Speed limit requirements can force drivers to slow down and increase reaction time, thus reducing the risk of traffic accidents.
Precautions for driving in foggy, rainy and snowy days:
1, slow down: when the visibility is 30-50 meters, the speed should not exceed 30 kilometers per hour, when the visibility is less than 30 meters, it should not exceed 20 kilometers per hour, and when the visibility is only 10 meters, it should not exceed 5 kilometers per hour.
2, the correct use of lighting: If you encounter foggy days, you need to turn on fog lights, width lights, low beam lights, not only pay attention to vehicles and pedestrians, but also make it easy for others to see their own vehicles.
3. Remove the water from the windshield and rearview mirror: Fog, rain and snow will cause water droplets and frost to condense on the windshield and rearview mirror, which will affect the driving sight. If cleaning is needed, you can turn on the wiper. If there is water mist on the glass inside the car, you can turn on the air conditioner inside the car.
To sum up, when driving a motor vehicle in bad weather with visibility less than 50 meters, the maximum speed should not exceed 20 kilometers per hour, and additional safety measures should be taken.
