Should driving a motor vehicle in foggy weather turn on the high beam to improve visibility?

Fog lights and danger warning flashlights should be turned on in foggy days. The distance of fog light propagation is very short, and driving far light can not improve visibility.

Reasons for not using high beam in foggy days:

The light emitted by the high beam of the car shines forward and upward, and the light reflected by the fog will travel in the white area in front of the car, which will not only be unable to illuminate, but also seriously block the driver's line of sight and vision. When the rear vehicle uses the high beam, it will also seriously affect the driver's observation of the rear situation.

Precautions for driving in foggy days:

1. According to the suggestion of the traffic department, the most correct way is to slow down, keep a sufficient safe distance from the car in front, turn on the fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and guide the line of sight with the help of the road markings and taillights of the car in front to avoid sudden braking and slamming the direction.

2. If the visibility is less than 200 meters, the speed must be limited within 60 kilometers; 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, drive out of the nearby expressway or enter the service area for temporary shelter until the fog clears.

In the special foggy weather, the speed of vehicles on the road is very slow. Don't exceed the speed of the same car at this time, and drive slowly together. If the vehicles in the distance can't see clearly, simply slow down and keep a distance from the vehicles in front, but be sure to keep a good distance and speed.
