What is the period of validity of the authorisation for occasional passenger services (national) with coaches or buses?

You answered this question correctly. In Germany, the authorisation for occasional passenger services (national) with coaches or buses is valid for a maximum of 10 years. This means that operators must renew their authorisation after 10 years if they wish to continue providing such services. The rule ensures that the operator’s qualifications and compliance with relevant regulations are regularly checked. For similar questions, remember that the 10-year limit applies specifically to national occasional passenger services using coaches or buses.
