Fog is a limitation of vision due to small water droplets floating in the air. In fog, visibility at the Earth's surface is less than 1000 meters. Fog is an annoying appearance in traffic that can occur all year round but can be more persistent in the autumn and winter. Your vision is very limited and this can lead to dangerous situations in traffic. Road and air traffic is greatly hindered by fog; of poor visibility on roads and runways. Traffic can be affected if visibility is less than 400 meters. Dense fog with visibility less than 200 meters is dangerous. Very dense fog with a visibility of less than 50 meters forces you to drive at walking pace. Sometimes you have so little visibility that you can't even see the car in front of you. What is the best thing to do if you have to hit the road in the fog, or are suddenly overtaken by local dense fog on the way.

Reducing your speed is the first thing you do, this way you increase the distance between you and your predecessor and you have more time to react to your predecessor. You must turn on the correct lighting in your car. Use your low beams, you should absolutely not use high beams because this only limits your view and can dazzle oncoming traffic. You may only use fog lamps in very dense fog, you can switch on your front fog lamp when visibility is less than 200 meters and you can switch on your rear fog lamp when visibility is less than 50 meters. Many cars today have automatic lighting, which turn on automatically when it gets dark. Many drivers have the button for the dipped beam on automatic and think that it comes on automatically under all circumstances, including fog. But that doesn't work like this, the sensor that sees whether the light or dark has been recognized is not missing, so this low beam you have to turn it on and off yourself.
