Högertrafik - Rösta Ja

An iconic and historically significant Swedish political poster designed by Fritjof Pedersén for the 1955 referendum campaign on changing Sweden from left-hand to right-hand traffic.

The poster features Pedersén's distinctive, playful graphic style. A cyclist stretches out an arm signal while sharing the road with a truck, accompanied by the simple message "Högertrafik är säkrare" ("Right-hand traffic is safer"). In the lower right corner, voters are urged to support the proposal with the slogan "Rösta JA" ("Vote Yes") for the referendum held on 16 October 1955.

The campaign became one of the most memorable public information efforts in Swedish history. Despite extensive arguments in favor of the change, the referendum resulted in a decisive rejection, with 82.9% voting against the introduction of right-hand traffic. Nevertheless, the Swedish Parliament later approved the reform, and the historic traffic change known as "Dagen H" was ultimately implemented on 3 September 1967.

Today, posters from the referendum are highly sought after, not only as examples of mid-century Scandinavian graphic design but also as artifacts documenting one of Sweden's most debated public policy decisions. Pedersén's bold use of color, simplified forms, and childlike visual language creates an image that remains instantly recognizable decades later.

The poster is in great condition, with only a tiny tear and minor surface dirt. A rare and fascinating piece of Swedish social and transportation history.
