What must be clearly marked in buses?

In German traffic regulations for buses, it is important that certain information is clearly marked to ensure safety and accessibility. Specifically, the location of the first-aid kits must be easily identifiable in case of emergencies, so passengers and drivers can quickly find medical supplies. Additionally, seats reserved for severely disabled persons in regular traffic must be clearly marked to guarantee accessibility and priority seating for those who need it most. Other items, like on-board tools, do not have a legal requirement to be marked in the same way. Knowing these markings helps maintain safety and social responsibility in public transportation.
