When driving on a foggy day, you should turn on the front and rare flog lights. If the fog is very heavy, you should also turn on the dual flashing lights at the same time to let other drivers notice you better, so as to avoid accident.
What you need to pay special attention to is that you should not use the high beam when driving in fog. Because the light emitted by the high beam is easily reflected by the fog, forming a white area in front of the car, making the driver invisible and easily causing an accident.
