I will be moving out of Germany for 4 months to work in another EU country. I have a German car registered to my current German address. However, during my 4 months abroad, I won't be registered at that address. After the 4 months, I will re-register in the same German address. My question is:
- Do I need to do anything for my car? Can I still use it with the current German plates?
- Do I need to inform my car insurance about the change?

Any information in this direction is much appreciated!
