What does a white license plate starting with 'sd' represent?
3 Answers
A white license plate starting with 'sd' represents vehicles belonging to the Equipment Department of the Shenyang Military Region. White license plates are commonly seen on vehicles used by public security departments, judicial departments, procuratorates, as well as the armed police and the People's Liberation Army, which are state power institutions. Generally, the letter 'A' stands for courts, 'B' for procuratorates, 'C' for the Ministry of State Security, and 'D' for judicial courts. The colors of domestic vehicle license plates in China include: 1. Blue: Vehicles with blue plates are mostly sedans or small-tonnage trucks, which are the most common type of license plates; 2. Yellow: Vehicles with yellow plates are mostly large trucks, trailers, etc., and some family cars exceeding six meters in length also require yellow plates; 3. Black: Vehicles with black plates mostly belong to consulates, and the YueZ plates issued in Guangdong are also black; 4. Green plates: Vehicles with green plates are new energy vehicles, with small new energy vehicles having gradient green plates and large new energy vehicles having yellow-green dual-color plates.
My son recently got into a military academy and happened to research military license plates. The white plates starting with SD belong to military vehicles, easily recognizable by their white background with black characters. The S represents the former Shenyang Military Region (now retained by the Northern Theater Command), and D is the code for a specific unit under that region. Military license plates follow strict lettering rules—for example, H is for the Navy, and K is for the Air Force. When you see an SD plate on the road, be extra careful to yield. Last time I encountered a convoy of such military vehicles, I immediately pulled over to let them pass. These plates occasionally appear in the city, mostly on military support vehicles.
I'm a car enthusiast, and license plate classification is my forte. The SD white license plate belongs to military vehicles, specifically those from the Shenyang Military Region. These plates feature black characters on a white reflective background, distinctly different from regular blue plates or new energy green plates. The second letter 'D' on military plates indicates specific military units, with different letters corresponding to different branches of the armed forces. I remember seeing a military off-road vehicle with an SD plate at last year's auto show—it had an overwhelming presence. Besides SD, other series like SA and SB also belong to the Shenyang Military Region. These military vehicles refuel through specialized channels, not visible at ordinary gas stations.
