Princess versus B9 - She lost

One managed to lose the cycle track in the pouring rain and the ´9´yellow road turned into a B9 dual yellow carriageway. So needless to say, the Polizei caught up with us rather quickly, lights ablazing and informs us as he winds the window down ´You are not allowed on the B9'!!!!!! REALLY, so then with lights still flashing, we were ´escorted´off!!!!!!!
