Iceland never ratified the Vienna Convention on Road Signs and Signals, but road signs in Iceland conform to the general pattern of those used in most other European countries, with certain design elements borrowed from Danish and Swedish practice.
Signs tend to be more sparsely employed than in other European countries, especially in rural areas.
Icelandic road signs most closely resemble their Swedish counterparts, with rounded corners and yellow backgrounds.
The original legal source for these are the Icelandic Transport Authority,[1] first ratified in article 289/1995[2] and subsequently amended in 2019 by 365/2019[3] and 548/2019.
Directional signs within the urban Capital Region of Iceland (including Reykjavík and its surrounding areas) have a blue on white design.
