German LGV driving bans. (The WHOLE story...)

there is at least one more exeption to the StVO, I carry a permit from hansestadt Lübeck that says I am allowed to run during the holidays from the port to the applicable bundesgrenze, not to a loading inside germany, only to the border and from the border to the port, it cost €80 for 6 months, the saturday ban still applies. I pull a curtainsider.
