Road signs in Uzbekistan are regulated by the O'zDst 3283-2017 standard.[1] Due to the country being a former Soviet Socialist Republic between 1924 and 1991, road signs are similar in design to those used in the Soviet Union before its dissolution in 1991, as well as in most other post-Soviet states. Uzbekistan acceded to the Vienna Convention on Road Signs and Signals on January 17, 1995.[2] [3] The Soviet Union itself was once a signatory to the Vienna Convention on Road Signs and Signals.[4]
Modern road signs in Uzbekistan are in many ways similar in design to road signs used in Russia and are based on the Soviet ГОСТ 10807-78[5] standard (no longer valid in Russia since January 1, 2006) and the Russian ГОСТ Р 52290-2004 standard.[6] [7] The ГОСТ 10807-78 standard is still valid in Uzbekistan, but with additions. However, modern road signs in Uzbekistan also have some design features used on road signs in European countries such as Spain, Germany and Italy.[8] Inscriptions on road signs in Uzbekistan are written in Latin script only, despite the use of Cyrillic and Latin alphabets in the country.
Temporary warning, priority and prohibition signs differ from permanent ones in that they have a yellow background instead of white.
