Where can you find the details of the inspection period of a fire extinguisher carried in the vehicle?

Your selected options are correct because both the inspection tag of the fire extinguisher and the maintenance log provide crucial information about the inspection periods. According to German traffic regulations, having a properly maintained and inspected fire extinguisher is vital for safety in vehicles. The inspection tag typically lists the next inspection date, while the maintenance log records past inspections and any service done, ensuring accountability for vehicle safety equipment. The third option regarding the adhesive seal on the registration certificate is not relevant to the inspection of fire extinguishers, which is why it's not included in the correct combination. Understanding all relevant sources for safety inspections helps ensure vehicles are compliant with regulations and equipped for emergencies.
