The following facts: 1. I have received a ticket in Germany somewhere near Freiburg (except for the tolerance deduction 8 km/h too fast in an 80′ zone). 2. It is an OWi with an amount of 10 Euro. 3. I am registered in Switzerland, but not in Germany. 4. In Germany I rented myself into a boarding house. 5. I also did not have a letter box in Germany. 6. I drove with e in my client’s rental car (I am a freelancer). 7. The process is already one month ago. 8. I am threatened with 20 Euro fees and expenses of 3.50 Euro. 9. The car is a rental car. 10. The warning was sent to the boarding house (in which I do not have a mailbox). 11. As far as I know, Switzerland does not drive OWi from D. Well my questions. Do not have to be sent to the correct address if the penalty notice is required? Is this warning Because of the wrong address not ineffective? Do not the penalty office have to determine the correct address (which is deposited with the Federal Foreign Office)? What can happen to me when I ignore the letter? And please no posts according to the motto “You pay what you did…”. I am interested in the different alternatives. Nothing else. I was even close to paying. But without IBAN/BIC it is not quite that easy.
