Road signs in Norway are regulated by the Norwegian Public Roads Administration, Statens vegvesen.
Signs follow the general European conventions concerning the use of shape and colour to indicate function. Any text included on supplementary signs will normally be in Norwegian, but may in some cases be bilingual. In Northern parts of Norway, municipal and informative signs may be printed in both Norwegian and Sami. In areas close to the Russian border, signs may be written in both the Latin and Cyrillic scripts.
No more than three signs (road number indications excepted) may be mounted on any one pole, with the most important sign appearing at the top. As is customary in European countries, all signs are partly or fully reflectorized or are provided with their own night-time illumination.
The current set of designs were introduced through a reform that went into effect 1 June 2006, replacing the old set from 1967. As the law outlining this reform was published 7 October 2005, some signs were already replaced before the law went into effect. The most notable change was the removal of hats and hair on the stickmen making them gender-neutral, but many signs were redesigned or introduced for the first time, as noted below.
Warning signs are mostly triangular, with black symbols on a white background with a red border. Warning signs that are used only temporarily have a yellow background. On Svalbard, a unique warning sign with a black background and white symbol is used for polar bears.
