Why Do Some Sedans Have Yellow License Plates?

[MacAllie]

The reasons why some sedans have yellow license plates include exceeding length limits, meeting weight requirements for yellow plates, or being classified as special vehicles. The specific reasons are as follows: Exceeding Length Limits: If the vehicle's body length exceeds 6 meters, it requires a yellow license plate. A sedan with a yellow plate indicates that its body length is too long to meet the blue plate standards for sedans, thus necessitating a yellow plate. Meeting Weight Requirements for Yellow Plates: Vehicles with a total mass of 4.5 tons (inclusive) or more, or those designed to carry 20 passengers (inclusive) or more, must display yellow license plates. Special Vehicles: Sedans used by driving schools, taxis, and other commercial vehicles are required to have yellow license plates. Additionally, yellow-plated vehicles need an operating permit and must undergo quarterly inspections. Furthermore, yellow-plated vehicles require a special permit to drive in urban areas.
