Road signs in Iran are regulated by both INSO standard 14815-1 and 14815-2. They generally follow the Vienna Convention on Road Signs and Signals and their designs both influenced by British and German road signage designs.
Road signs are divided in three categories:
Regulatory signs; Warning signs; Information signs. History Iran signed the Vienna Convention on Road Signs and Signals on November 8th, 1968 and ratified it on the date of May 21, 1976.
Pictogram inspired signs were a common sight in urban Iran even before the Pahlavi dynasty signed the Vienna Convention, 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.
