Against the background of studies on redundancy in law that completely omit the visual element in law and of studies on traffic signs that are laconic about their redundancies, the present study proposes more focused investigation into the redundancies of traffic signs. After presentation of the broader context of existing studies on traffic signs and on redundancy in law, and following a discussion of the direct inspiration for embarking upon research into this topic, the article moves to present and discuss (...) six proposed types of redundancies of signs. Utilizing Franciszek Studnicki’s distinction between sign-types and sign-realizations, and given that traffic signs exist in various complicated relationships with each other, with written formulations in legal texts, and with the environments in which they are placed, the study comments on six types of redundancy: sign-type–basic task of road traffic law; of sign-type’s elements; sign-type–sign-type; sign-type–legal text; sign-realization–sign-realization; and sign-realization–environment. Analysis of each type is supported through examples, various subdivisions, and additional lines of inquiry. The study has value for both strictly theoretical and more practical enterprises related both to traffic signs themselves and to the wider realm of visualization of norms. (shrink)
