What is the minimum number of operative fire extinguishers which must be carried on a bus (single deck)?

According to German traffic regulations, every single-deck bus must carry at least one operative fire extinguisher for safety reasons. This ensures that in case of a fire emergency, the driver or passengers have the means to respond quickly and potentially prevent a dangerous situation. There is no requirement for more than one extinguisher based solely on the number of passenger seats in a single-deck bus. The rule is straightforward: one operative fire extinguisher is mandatory regardless of bus size or seating capacity. This helps keep safety measures clear and consistent.
