Why must you also drive with dipped headlight during the day when visibility is impaired by fog, rain or falling snow?

Driving with dipped headlights during the day when visibility is impaired by fog, rain, or falling snow is essential for safety. The main reason is to ensure that you are more easily seen by other road users, reducing the likelihood of accidents. This helps other drivers recognize your presence on the road, especially in conditions where visibility is significantly reduced.

Additionally, while it may seem that driving with dipped headlights could help in seeing traffic signs better, this is not the primary purpose of using headlights in poor visibility conditions. The focus should be on enhancing your visibility to others rather than primarily improving your ability to see.

According to German road traffic rules, specifically the Road Traffic Act (Straßenverkehrs-Ordnung or StVO), it is emphasized that drivers must ensure visibility to both themselves and others on the road. Therefore, understanding and applying this combination of choices—ensuring visibility for everyone—is key to safe driving in adverse conditions.
