An inspection has been performed because of a technical modification made to your vehicle. What are you obliged to do?

You selected answer 1, which is correct. After a technical modification to your vehicle, you are required to carry the inspection report or confirmation document with you, and if needed, have your vehicle’s registration certificate Part I updated. This ensures that you can prove the modification has been properly inspected and approved, which is required by German law. You do not need to send the report to the vehicle manufacturer or attach it to the registration certificate Part II. Always remember to have the proper documentation in your car, as police or authorities may ask for proof during a check. This rule helps ensure all vehicles on the road remain safe and compliant after modifications.
