Road signs in Mongolia are similar to the Soviet (post-Soviet states), British, and other European road sign systems. Road signs are regulated in the MNS 4597:2014 standard and conform to the general pattern of road signs as set out in the Vienna Convention on Road Signs and Signals.^[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.^[5][6][7][8] Mongolia acceded to the Vienna Convention on Road Signs and Signals on December 19, 1997.^[9]

The Arial Bold typeface is used on road signs in Mongolia. 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.
