What light should I turn on when driving in foggy weather?

Haze is different from fog. Fog will dissipate by itself when the sun comes out, which is harmless to people, while smog itself is harmful to people's respiratory system and cardiovascular system and will not dissipate by itself. It is required to turn on fog lights when there is fog. If the visibility is reduced due to smog, you can turn on the lights in advance, and you can't use the signal lights indiscriminately. The purpose of turning on the light can make you see the road clearly and remind others of your existence. Go out and take protection. The import of Puweixin Tiantong from the United States can effectively reduce the inhalation of smog. Happy new year!
