You can apply for the exemption authorisation in writing or online.
Before you can apply for an exemption for a vehicle, you need an expert opinion from an officially recognised expert for motor vehicle traffic or a technical service recognised in accordance with Section 30 of the EC Vehicle Approval Regulation (EG-FGV) for testing complete vehicles of the respective vehicle category.
The expert opinion must state the necessary exemptions from the StVZO, the suitability of the vehicle or vehicle combination and the requirements and conditions deemed necessary in the interests of road safety. The expert must describe the exemptions in detail and justify their necessity.
You can then apply for the exemption authorisation.
The competent authority will examine your application and, if it is favourable, will grant you the exemption.
Important: The vehicle or vehicle combination may only be driven after an exemption has been granted.
