While driving in thick fog, are you always obliged to exercise special caution?

In the video, you are driving in thick fog on a road through fields, along a line of trees, and a lorry emerges from the opposite direction, visible only from a short distance. When driving a vehicle in fog, you are obliged to exercise particular caution. The answer is: yes.

The Road Traffic Act requires the driver to exercise particular caution when driving in reduced visibility caused by fog, precipitation or other causes, and also to switch on dipped headlights or front fog lights. Particular caution means increased attention and adapting your behaviour to the conditions - in fog you drive so slowly that you can stop within the distance you can see, you increase your following distance from the vehicle in front and you do not overtake.

Legal basis: Art. 30 para. 1 point 1 and Art. 2 point 22 of the Road Traffic Act (Prawo o ruchu drogowym)
