Road signs in Kazakhstan are similar to the road sign system of other post-Soviet states that ensure that transport vehicles move safely and orderly, as well as to inform the participants of traffic built-in graphic icons.
Road signs are regulated by the СТ РК 1125-2021 standard.
[1] Road signs in Kazakhstan are in many ways similar to road signs used in neighboring Russia and derived from the Soviet ГОСТ 10807-78 (no longer valid in Russia since January 1, 2006),[2][3] modern Russian ГОСТ Р 52290-2004[4][5][6] and Belarusian СТБ 1140-2013[7] standards as well as in the countries of the Eurasian Economic Union.
[8] However, СТ РК 1125-2021 has some differences from its Russian counterpart ГОСТ Р 52290-2004: On January 1, 2004, the Kazakh state standard for road signs СТ РК 1125-2002 came into force in Kazakhstan to replace the ГОСТ 10807-78 standard that had been in force since Soviet times.
However, Arial is often de facto used on road signs in Kazakhstan instead of one based on the ГОСТ 10807-78, similar to neighboring Russia and most other post-Soviet states.
