How dangerous are advertising and information billboards alongside the road?
Advertising and information campaigns alongside the road are meant to catch the drivers' attention, leaving them less room to concentrate on the traffic situation. Although campaign boards alongside the road are meant to improve road safety they divert the attention and lead to more crashes, just as advertising boards do.
However, not much is known about the relation between advertising and campaign boards and road crashes. It is known, however, that advertising boards with moving parts particularly attract attention, and boards at road level attract more attention than those higher up. Studies indicate that it is better not to place advertising and campaign boards at busy locations, and that it is better not to allow them to look like road signs.

Which guidelines for placing advertising and campaign signs are there?
For national roads, the guidelines for placing advertising and information boards are clear: advertising billboards are not allowed near roads except at petrol stations and service areas. Boards aimed at improving road safety and information boards about roadworks are allowed.
The guidelines of the Ministry of Transport do not apply to other roads. The province or municipality determines if they allow a board. Each province and municipality is free to have its own guidelines and they can be different from the Ministry's. There should be unambiguous guidelines for placing advertising and campaign boards alongside the road.
