Road signs in the post-Soviet states Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan are largely similar to the Soviet road sign system, as these countries were part of the Soviet Union until its dissolution in 1991.
Modern road signs in Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan comply with the Vienna Convention on Road Signs and Signals as well as most European countries.
In general, warning signs in post-Soviet states have a triangular shape with a red border and a white background, as in most European countries.
In Belarus and Lithuania, road signs with the names of the built-up areas in may also feature a building silhouette.
In Armenia and Georgia, road signs with the names of settlements are in two languages: Armenian and English in Armenia, and Georgian and English in Georgia, due to the fact that these countries use scripts other than Cyrillic and Latin in their official languages.
In Ukraine, in accordance with the new road sign standard DSTU 4100:2021, the names of settlements are written in Cyrillic and Latin.
[27] In Moldova, there is a slightly different version of the road sign indicating the entrance of built-up areas: on top, it has the building silhouette on the right and a sign indicating the maximum speed limit on the left, or only the building silhouette in the center, on a yellow background, and on the bottom, it has the name of the built-up area on a white background, similar to Romania.
Most post-Soviet states use border road signs with the names of the countries that display their flag and/or coat of arms.
However, unlike most European Union countries, Estonia has a border road sign with the coat of arms on the left, the 12 stars of the European Union on the right, and the country names EESTI VABARIIK and REPUBLIC OF ESTONIA in Estonian and English, respectively, in the center.
Road signs used in unrecognized and partially recognized states formed on the territory of the former Soviet Union such as the Transnistria, Abkhazia and South Ossetia are generally modeled on those used in modern Russia.
