Road signs in Uzbekistan are regulated by the O'zDst 3283-2017 standard.
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are in many ways similar in design to road signs used in Russia and are based on the Soviet ГОСТ 10807-78[5] standard (no longer valid in Russia since January 1, 2006) and the Russian ГОСТ Р 52290-2004 standard.
Temporary warning, priority and prohibition signs differ from permanent ones in that they have a yellow background instead of white.http://www.adcidl.com/pdf/Uzbekistan-Road-Traffic-Signs.pdf
