When are you allowed to use fog headlamps also during the day?

The allowed use of fog headlamps during the day is specified under German traffic regulations. You are permitted to use fog headlamps when there are conditions that significantly reduce visibility, such as fog or falling snow (choice 1) and during rain (choice 2).

These conditions can make it difficult for other drivers to see you or for you to see the road clearly. Thus, using fog headlamps helps improve visibility and enhances safety on the road.

However, you should not use fog headlamps solely for ice on the windscreen (choice 3), as this situation does not justify their use according to the laws regarding vehicle lighting. It's essential to choose all relevant options because each specific condition contributes to the overall understanding of when using fog lights is necessary for safety.
