A wide variety of road signs are displayed in the People's Republic of China.China's traffic signs also closely followed those used in Europe, the US, and Japan. China is not a signatory to the Vienna Convention on Road Signs and Signals.[1] Despite the fact that Chinese is one of the 6 official languages of the United Nations and China is a permanent member of the UN Security Council, China itself has never signed this convention, which was issued in all 6 official languages of the UN, including Chinese.
The signs are specified in the Guobiao standard GB 5678-2022.
The road signs used in the special administrative regions of Hong Kong and Macau differ from those used in the rest of China.
Warning signs are triangular in shape, as in Europe, but unlike European countries, warning signs in China have a black border and a yellow background instead of a red border and a white or yellow background. This makes it one of the few countries in the world using this type of warning sign.
