What is the period of validity of the authorisation for other occasional passenger services (national) with motor vehicles?

You answered correctly. In Germany, the authorization for providing occasional passenger transport services (national) with motor vehicles is valid for a maximum of 5 years. This means that after 5 years, the authorization must be renewed if you wish to continue offering these services. The rule ensures regular checks and updates on the operator’s compliance with safety and licensing requirements. Remember, this 5-year limit applies specifically to these national occasional passenger transport services; other types of permits may have different periods of validity.
