Road signs in Taiwan

Road signs in Taiwan are regulated by “The Regulations for Road Traffic Signs, Markings, and Signals”. (中文:道路交通標誌標線號誌設置規則)[1] To provide vehicle drivers and pedestrians with warnings, regulations, and other information related to road conditions, thereby facilitating travel and promoting traffic safety.
These signs can be categorized into four types: warning signs, regulatory signs, information signs, and auxiliary signs. The English text and numbers on the signs use Highway Gothic.
The Republic of China is a signatory of the “Vienna Convention on Road Traffic” and the “Vienna Convention on Road Signs and Signals”.[2][3]
Its road signs largely follow or are influenced by the 1968 edition of the Vienna Convention on Road Signs and Signals. They also draw inspiration from many road signs in Europe, the United States (for example, construction signs adopt the diamond-shaped design from the MUTCD), and Japan (for example, the two-stage left turn sign for motorcycles and slow-moving vehicles).
However, certain signs specified in the Convention (such as pedestrian crossing signs and priority road signs) are not used in Taiwan.
