Just quietly, drive safely

Going from what has to be the loudest advertisements (electoral campaigning) to what has to be the smallest ads I’ve seen so far. Consisting of a yellow plastic strip strapped around the trunks of trees or lampposts using twist ties.

As far as I can make out there are two types of advisories. One to drive safely, the other, literally translated, speeding forbidden. All from the local police station. If anything, they make a nice composition to take a picture of.
