What size of vehicle requires a blue license plate, and what size requires a yellow one?

[Alejandro]

Vehicles exceeding 6 meters in length must use yellow license plates, while those within 6 meters use blue plates. Types of license plate colors: There are four base colors for vehicle license plates: blue, yellow, white, and black. Blue plates generally refer to small vehicle plates; yellow plates are for large vehicles, agricultural vehicles, and training vehicles, with motorcycles and test vehicles also using yellow plates; white plates are specifically for special professional vehicles such as military, police, and racing cars; black plates are for vehicles brought from abroad by foreign investors and their enterprises. Requirements for driving licenses: A Class B or above license is required to drive vehicles with yellow plates, while a Class C or above license is sufficient for blue-plated vehicles.
