Even my friend in Germany is stumped. Here is the literal translation:

Rechtsschutz
Rechts = Justice
Schutz = Protection
Bundesländer = States
Versicherung = Insurance

The compound word Rechtsschutz is what is not making any sense. It is either a brand name or who knows what. She says she is going to go ask her brother, because this is like, a car thing.

Was there anything else on the sticker?
