Why are license plates half yellow and half green?

[Morris]

License plates that are half yellow and half green, also known as yellow-green dual-color plates, are special license plates designated for large new energy vehicles. Below is expanded information about new energy vehicle license plates: 1. Compared to traditional ordinary vehicle license plates, new energy vehicle license plates feature a special emblem. The emblem uses green as the base color, symbolizing eco-friendly new energy, and includes an electric plug pattern. The license plate number for new energy vehicles has also been increased from the traditional 5 digits to 6 digits. 2. The dimensions of new energy vehicle license plates are 480mm×140mm. They are categorized into large new energy vehicle license plates and small new energy vehicle license plates, with the small ones featuring a gradient green color. New energy vehicle license plates primarily use green as the main color, making them distinctly different from regular motor vehicle license plates and easy to identify.
