[1][2][3][4] Despite the fact that Mongolia was never part of the Soviet Union, the MNS 4597:2014 standard for road signs has many similarities with its post-Soviet counterparts based on the Soviet standard ГОСТ 10807-78 and the Russian standard ГОСТ Р 52290-2004.

Unlike most post-Soviet states, Mongolia does not use the typeface based on the ГОСТ 10807-78 Soviet standard.
The Arial Bold typeface is also often used on road signs in Russia and post-Soviet states since it is a computer font and is included with all PCs running Microsoft Windows and Apple's macOS.
