Are avoidable noises such as honking horns prohibited by the German traffic ordinance?

Honking horns is generally prohibited by the German traffic ordinance unless it is used for necessary warning purposes. This regulation aims to minimize noise pollution and promote a more peaceful environment, especially in residential areas. The ordinance is designed to ensure that use of the horn is limited to situations where it is essential for safety, such as alerting another driver of an imminent hazard. Therefore, if a driver uses the horn for avoidable circumstances, it would be deemed inappropriate and possibly subject to penalties.

In contrast, the other choices might imply conditions under which honking could be acceptable, but the essence of the regulation is to restrict the use of car horns to what is necessary, reinforcing the proper conduct on the roads for the safety and peace of the community.
