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 bi- or trilingual. In Northern parts of Norway, municipal and informative signs may be printed in both Norwegian and Sami. Close to the Finnish border and in municipalities with significant Norwegian Finnish population signs and village names are also shown in Finnish. In areas close to the Russian border, signs may be written in both the Latin and Cyrillic scripts.
