On buses used for passenger transport that are required to have a complaints book, is it mandatory to display a sign inside the vehicle indicating its existence?

Question

DentroTest · Accepted Answer

The regulations governing land transport establish that, in vehicles intended for passenger transport that are required to have a complaints book or complaint forms, a sign or information notice must be placed visibly inside the bus expressly informing users of the existence of that book and of their right to make complaints. Therefore, it is not a voluntary measure, nor is it enough to keep the book on board without signage.
