When driving on foggy roads, you should use the horn more often to alert oncoming vehicles. If you hear an oncoming vehicle's horn, respond by honking your own.

In fog, visibility is poor and other vehicles are hard to see. Drivers often rely on sound to locate other vehicles, so honking is a common way to communicate. When you hear another vehicle honk, signal your own location to avoid accidents caused by poor visibility.
