Abstract
The article discusses the issues related to the legalisation of an advertising medium located by a public road at the distance that is shorter than the one required by the Act on public roads. Both the type of the medium and its location affect the obligation to notify an organ or obtain a building permit. A special issue in this regard is the possibility of obtaining a road administrator’s consent for the placement of an advertising device in spite of the fact that the minimum distance of advertisements from the outer edge of a road was not taken into consideration in the course of the legalisation proceeding. Despite the lack of legal regulations of this matter, possible solutions are indicated.
