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

Lights that should be turned on when driving in foggy days are:

1. When driving in foggy weather, both front and rear fog lights should be turned on. If the fog is heavy, you can turn on the double flashing lights. The main function of turning on fog lights and double flashing lights is to remind other drivers to avoid rear-end collision and scraping accidents.

2. When there are no fog lights, turn on the width indicator and double flashing lights to attract the attention of other drivers.

Don't turn on the high beam in foggy days. Turn on the high beam, the front will turn white, which will make the line of sight more blurred. Therefore, it is suggested that the driver can use the high beam as a signal light to ensure that the other driver will be reminded when passing, but the flashing time of the high beam should be extremely short, so as not to affect the line of sight of the other driver and cause an accident.

Precautions for driving in foggy days:

1, drive carefully when the fog is light, and beware of rushing into the dense fog area: the fog has a strong regional and regional appearance, and the place where you may be is covered with fog, but it is sunny 500 meters ahead.

When there is fog, no matter how serious it is, you should slow down and walk slowly, and beware of suddenly rushing into the local fog, or the fog suddenly thickens and fog appears at high speed. At this time, it is easy to have a sudden drop in visibility, and drivers have no time to slow down, which is easy to cause traffic accidents and even major accidents of serial collisions.

2. Take three roads in the middle and two roads on the left: In foggy days, not only drivers can't see the road clearly, but pedestrians and cyclists on the road have blurred vision, so it is easy to accidentally break into adjacent lanes.

In this case, drivers are required not to drive along the edge of the road, so as not to see the cars and pedestrians that have strayed by mistake and cause accidents. If you are driving on a road with three lanes, you should try to choose the middle one. If you drive on a two-lane road, you should try to stay away from the crowd and drive slowly.

3. Reasonable use of car lights in foggy days: The correct use of car lights is an important factor to ensure the safety of driving in foggy days. When driving in foggy weather, the driver should turn on all the front and rear fog lights, and if the fog is heavy, he can also turn on the double flashing lights. The main function of turning on fog lights and double flashing lights is to let drivers of other vehicles observe better and avoid rear-end collision or scraping accidents.
