Where is the license plate number Su O from?

[LaDaniela]

Su O is the license plate number for administrative official vehicles of provincial-level Party and government organs, as well as public security, court, procuratorate, state security, and judicial systems in Jiangsu Province. The license plate numbers for various regions in Jiangsu Province are as follows: Su A is Nanjing, Su B is Wuxi, Su C is Xuzhou, Su D is Changzhou, Su E is Suzhou, Su F is Nantong, Su G is Lianyungang, Su H is Huaiyin, Su J is Yancheng, Su K is Yangzhou, Su L is Zhenjiang, Su M is Taizhou, Su N is Suqian. Jiangsu, abbreviated as Su, is a provincial-level administrative region of China, with its capital in Nanjing. The name is derived from the first characters of Jiangning Prefecture and Suzhou Prefecture. Jiangsu Province governs a total of 13 prefecture-level cities, 22 county-level cities, 19 counties, and 55 municipal districts.

I've been driving for many years and often encounter license plates starting with 'Su O' on the highways in Jiangsu. At first, I thought it might be for a new district in Suzhou, but later I realized it's completely different. These are actually provincial-level government license plates, specifically used for vehicles belonging to public security bureaus or government agencies. For example, in Jiangsu, 'Su A' is for Nanjing vehicles, 'Su B' is for Wuxi vehicles, but 'Su O' represents a unified management system across the province, with many police cars or official patrol vehicles using this type of plate. Whenever I see them on the road, I'm extra cautious because these vehicles are on official duty. I avoid following too closely to prevent misunderstandings or interfering with official business. Remember, these plates aren't for ordinary citizens—they're unique to Jiangsu, though other provinces also use 'O' for similar purposes to make vehicle identification clearer. Knowing this makes driving a bit safer.

As a driver who frequently operates in Nanjing, I have some knowledge about license plates. The 'Su O' license plates are not for just anyone to use; they are exclusively for vehicles at the Jiangsu provincial government level, such as those in the public security system or for high-ranking officials. Different regions in Jiangsu have their own letter codes, like 'Su C' for Xuzhou, but the 'O' series is special, reserved for provincial-level units, making it easier to quickly identify official vehicles. I find this design quite clever—it helps reduce the issue of fake plates and reminds the public not to honk or tailgate when encountering them, as official business takes priority and disrupting order is unacceptable. Paying attention to these details in daily driving can help avoid trouble.

I have studied license plates for some time and learned that the 'Su O' plate represents vehicles owned by Jiangsu Province's public security or provincial government agencies. Jiangsu's license plates start with 'Su,' followed by letters indicating different regions, but 'O' is a reserved code for vehicles of major government institutions. When seen in daily life, it helps identify them as official vehicles rather than private cars, contributing to order and safety.
