Traffic signs play an indispensable role in today's road traffic. Especially with the continuous increase of car ownership, traffic signs can provide necessary guidance for pedestrians and drivers, so that people and vehicles can pass in an orderly manner according to traffic rules. The role of traffic signs is so great, how did it develop? In 1901, the British Auto Union erected the world's first warning signs for automobiles on the top of Badlip Hill in Gloucester. This can be seen as the earliest traffic sign.

But these regulations were not accepted by all local authorities in the UK, so traffic signs were not uniform at the time, often causing confusion.

Since then, the traffic signs of various countries have gradually developed in the direction of international unity in terms of classification, color, shape and pattern. Driven by the efforts of the European Union, the United Nations and other international organizations, more and more countries have joined the unified movement of international road traffic signs and signals, trying to make new attempts to facilitate international traffic. In 1972, the Ministry of Communications and the Ministry of Public Security jointly promulgated road traffic rules, increasing the number of traffic signs to 34, including 9 indicating signs, 7 warning signs, and 18 prohibition signs.
