What is the Guangdong O license plate?

[DeRachel]

Guangdong O is the license plate code of the Vehicle Management Office of the Guangdong Provincial Public Security Department, designated for administrative vehicles of provincial-level Party and government institutions, directly affiliated enterprises and institutions in Guangdong Province, central institutions stationed in Guangdong, and public security, procuratorate, judicial, national security, and judicial systems across the province. Below are relevant details: 1. If the five digits following "Guangdong O" are all numbers, it indicates a license plate for Guangdong Party and government institutions, directly affiliated enterprises and institutions, or central institutions stationed in Guangdong. Additionally, the number segments are categorized as follows: numbers starting with 0 are for the Provincial Party Committee, 1 for the Provincial Government, 2 for the Provincial People's Congress, 3 for the Provincial Political Consultative Conference, 5 and 6 for directly affiliated enterprises and institutions under the province and central institutions stationed in Guangdong, 8 for the Provincial Public Security Department, and 9 for the Provincial Traffic Police Corps. 2. If the first character is an English letter, it represents administrative license plates for local public security, procuratorate, judicial, national security, and judicial systems (distinct from the white license plates used for operational tasks by police vehicles). 3. If the second character is A, it denotes the court system; B is for the procuratorate system; C is for the national security system; and D is for the judicial system.

During my days of driving around Guangzhou, I often saw Yue O license plates, which are exclusive to the police vehicles of Guangdong Province's public security organs. 'Yue' stands for Guangdong, and 'O' is the code for the public security system—it's not used for civilian vehicles. For example, regular private cars have plates like Yue A or Yue B. Recognizing this is important because encountering a Yue O vehicle on the road often means they might be on an emergency mission or patrol, so I need to yield or stay cautious to ensure safety. Additionally, China's license plate system is quite clever: a provincial code combined with letter combinations helps quickly distinguish vehicle types. This design is practical, avoiding confusion between law enforcement vehicles and civilian cars. Understanding these details gives me more confidence in handling various road conditions while driving.
