Traffic Signs in Bulgaria – Groups and Categories

Traffic signs are an essential part of every transportation system. They ensure order, safety, and clarity on the roads by guiding, warning, and informing road users. Without them, traffic would be chaotic and dangerous for both drivers and pedestrians.

A Brief History of Traffic Signs

The first traffic signs appeared in the late 19th century with the rise of automobiles. Initially, they were simple boards placed by automobile clubs across Europe. In 1903, the UK introduced the first official warning signs, and in 1909, an international conference in Paris standardized four universal hazard symbols.
With the development of road transport, a unified system became necessary. After World War II, the Vienna Convention on Road Signs and Signals (1968) set international standards, adopted also by Bulgaria.

Today, Bulgarian traffic signs are regulated by Regulation No. 18 of the Ministry of Regional Development, divided into several groups and categories based on their functions.
