The visibility of driving motor vehicles in foggy days is low, so you should turn on the high beam to improve the visibility. Is this sentence correct?
The reason why the high beam is not used in foggy days: the light from the high beam of the car shines forward and upward, and the light from the high beam will travel in the white area in front of the car after being reflected by the fog, which will not only fail to illuminate, but also seriously block the driver's sight and vision. When the rear vehicle uses the high beam, it will also seriously affect the driver's observation of the rear situation. So you can't use the high beam when driving in foggy weather.
Matters needing attention in driving in foggy weather
According to the suggestion of the traffic department, the most correct way is to slow down and keep a sufficient safe distance from the car in front, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and guide the line of sight with the road markings and taillights of the car in front to avoid sudden braking and slamming the direction.
If the visibility is less than 200 meters, the speed must be limited to 60 kilometers per hour; When the visibility is less than 100 meters, the speed must be limited to less than 40 kilometers per hour; If the visibility is less than 50 meters, the vehicle speed must be limited to less than 20 kilometers per hour. On the premise of confirming the safety of lane change, drive into the rightmost lane, leave the expressway or enter the service area to temporarily take shelter from the wind and wait for the fog to disperse.
