Road signs in Iran

Iran signed the Vienna Convention on Road Signs and Signals on November 8th, 1968 and ratified it on the date of May 21, 1976.^[3]

Pictogram inspired signs were a common sight in urban Iran even before the Pahlavi dynasty signed the Vienna Convention,^[4] often on a blank background; paired with Nastaliq text, and a bespoke Pictogram design.

By the late 70s, Iran's road furniture looked similar to the likes of Europe. ^[5]
