What s going on with the fact that some cars have a black background?

The background color of the license plate is blue, yellow, white, and black. Blue is the license plate of small cars (including small tonnage trucks) Yellow is the license plate of large vehicles or agricultural vehicles and the license plate of training vehicles, and there are test vehicles for new products and finalized test vehicles. Motorcycles are also yellow carded.

White is the license plate of special vehicles (such as military vehicles, police car license plates and racing car license plates) Black is the license plate of foreign companies and foreign enterprises that bring their own cars abroad. Large civil vehicles: black on yellow; Small civilian cars:

white on blue; Armed police special car: red "wj" on white background, black characters; Other foreign cars: white on black; Embassies and Consulates for Foreign Cars:

white characters on a black background and a hollow "make" logo; Test license plate: red on a white background, with the word "test" sign in front of the number; Temporary license: red on a white background, with the word "temporary" in front of the number; Car Replacement License Plate:

Black on white. In addition, the civil automobile license plate has the name of the province, municipality directly under the Central Government and the autonomous region and the code of the license issuing and supervision authority, and the number is an English capital letter. The car number at the back is generally 5 digits, that is, from 00001 99999.

When the number exceeds 100,000, it is replaced by English letters such as a, b, and c, that is, a represents 100,000, b represents 110,000, c represents 120,000, and the last letter and z represent 330,000. The i and o in the English alphabet are avoided to avoid confusion with the 1 and 0 in the numbers. The small number on the foreign automobile license plate of the embassy or consulate is the code of the country where diplomatic relations are established, and has nothing to do with the regulatory number of the region where it is located.

Black license plate refers to a license plate with a black background, which is used by foreign vehicles or foreign-funded enterprises. Other departments and individuals use it in a non-standard manner. When China first began to reform and open up and introduce foreign investment, the number of foreign-funded enterprises was very small, and because of their preciousness, their vehicles used black license plates.

The cars used by foreign-funded enterprises and foreign embassies and consulates in China have black license plates, and it may also be fake license plates, such as what track. Venues and so on!
