text: Hello, thanks for the note. This is a bit tricky: There is a restriction for HGV in the whole area of Karlsruhe Hagsfeld, but it depends on where you enter the area how strict it is (hgv=destination or hgv=no).
  I now marked all roads in the area with hgv=destination except of the ones where there are no HGV allowed at all (hgv=no). I hope this solves the problem.
