Background of the triangle warning sign being officially recognized as a warning sign

In the mid-20th century, with the surge in the number of cars and the acceleration of urbanization, the incidence of traffic accidents increased significantly. This phenomenon has aroused widespread concern about traffic safety around the world, and countries have realized the urgent need to develop a unified traffic sign system to reduce misunderstandings and accidents caused by inconsistent signs.
The signing of the Vienna Convention on International Road Traffic in 1968 was an important milestone in this effort. The convention aims to strengthen international cooperation in traffic safety and develop unified traffic rules and sign standards to improve the safety and efficiency of road use. In this context, the triangle warning sign was officially recognized as a warning sign, symbolizing a warning of potential danger. The convention stipulates that the triangle warning sign should have a red border and a white base to ensure high visibility in various environments.
The design concept of the triangle warning sign is based on the human psychology's response to visual stimuli. Red is usually associated with warnings and dangers, and the sharp shape of the triangle can quickly attract attention. This design ensures that drivers can quickly identify and respond when faced with emergencies, thereby effectively reducing the accident rate.
The international community is also increasing its demand for the standardization of traffic signs. Traffic mobility is increasing, making cross-border travel more common. To ensure that drivers from different countries can understand traffic signs on foreign roads without obstacles, the unified standards of triangular warning signs are particularly important. Through standardization, drivers can quickly adapt to roads in different countries, thereby improving driving safety.
