Road signs in Azerbaijan are similar to the road sign system of post-Soviet states (as well as neighboring Armenia, Georgia and Russia) that ensure that transport vehicles move safely and orderly, as well as They generally conform to the Vienna Convention on Road Traffic and Vienna Convention on Road Signs and Signals.
Since Azerbaijan was a union republic of the Soviet Union before regaining its independence in 1991, road signs in Azerbaijan are largely based on the GOST 10807-78 and GOST 23457-86 Soviet standards but with additions. Inscriptions on road signs are in Azerbaijani language (names of settlements can also be written in English) and in Latin script only.
In the Republic of Artsakh, a former breakway state formed during the First Nagorno-Karabakh War in 1991 and de-facto dissolved in September 2023, road signs with settlement names in Armenian, Russian and English were used. In September 2023 after the Azerbaijani offensive in Nagorno-Karabakh, Armenian-language road signs began to be removed.
