Why should you honk the horn more often when driving in heavy fog?

[DeJoseph]

When driving in heavy fog, honking the horn more often is to attract the attention of others and avoid potential dangers. Root cause: In foggy conditions, visibility is low, the driver's vision is blurred, the visual distance is shortened, and the field of view is narrowed. Honking the horn more often on the road alerts pedestrians and vehicles to avoid traffic accidents. Precautions for driving in fog: Drive slowly in foggy conditions. Never use high beams when driving in fog. Judge the situation promptly. Avoid unnecessary overtaking in fog. Maintain a greater following distance than usual when driving in fog. Use the horn frequently when driving in fog. Pay extra attention to pedestrians and motorized scooters.
