What is the difference between small blue license plates and large blue license plates?

[DiReid]

Here is an introduction to the differences between small blue license plates and large blue license plates: 1. Different quality: Trucks with a total mass below 4500KG are issued small blue license plates; trucks with a total mass equal to or greater than 4500kg are issued large blue license plates. 2. Different length: Vehicles with small blue license plates have a body length of less than 6 meters; vehicles with large blue license plates have a body length equal to or greater than 6 meters. 3. Different driver's license requirements: To drive a small blue license plate truck, a C1 or higher driver's license is sufficient. (C1 driver's license allows driving small and micro passenger cars as well as light and micro trucks; light and micro special-purpose vehicles); To drive a large blue license plate truck, a B2 or higher driver's license is required. (B2 driver's license allows driving heavy and medium-duty trucks or large, heavy, and medium-duty special-purpose vehicles, with heavy and medium-duty trucks mainly being trucks.)

The small blue license plate mainly refers to the common type of license plate for small private cars, featuring a blue background with white characters and a compact size, suitable for regular sedans or SUVs. I find driving such cars quite convenient—they are flexible for daily commutes, easier to park, and have lower maintenance costs. In contrast, large blue license plates are typically yellow-based and used for trucks or buses, which are larger and more eye-catching, designed to alert other drivers from a distance for safety purposes. The key difference lies in the vehicle type: small blue-plate cars are easier to drive and only require a Class C driver’s license, while large blue-plate vehicles demand a Class B or higher license, are harder to operate, and often face traffic restrictions (e.g., limited access to city centers) with stricter safety requirements. In the long run, small blue-plate cars suit family life better, whereas large blue-plate vehicles are more suited for freight work but involve more complex regulations. This difference influences driving choices—after years of driving, I believe smaller cars are more practical in urban areas.

The most intuitive differences between small blue license plates and large blue license plates lie in their appearance and applicable scenarios. Small blue plates are standard car plates with blue background and white characters, suitable for ordinary family vehicles. They look neat and compact, and their rear-mounted position gives a low-key impression. Large blue plates usually have a yellow background, appearing larger and more eye-catching visually, primarily used for trucks or buses. Their larger size facilitates long-distance identification. The number formats also differ, with car plates having shorter numbers while large vehicle plates have longer numbers or specific prefixes. I think this design serves traffic safety purposes: large vehicles are faster and heavier, so conspicuous plates can reduce rear-end collision risks. Small blue plates are simple and suitable for daily commutes, while large blue plates emphasize presence. Observing these details while driving is quite interesting—small car plates are more common, whereas large vehicle plates are seen more frequently outside cities. The colors and sizes reflect vehicle purposes, and a simple comparison can avoid confusion.

From a regulatory perspective, small blue license plates represent small vehicles such as sedans, requiring only a Class C driver's license to operate; large blue plates are typically used for heavy vehicles like trucks, which demand a Class B or A license with stricter testing requirements. In terms of restrictions, small vehicles can freely access most urban areas, while large vehicles often face time or area restrictions, such as being prohibited from entering the Second Ring Road during peak hours. Penalties for violations also differ: speeding or illegal parking by large vehicles incurs heavier fines due to their greater potential hazards. Regarding inspection frequency, small vehicles undergo biennial checks, whereas large vehicles require annual inspections. I believe this reflects a tiered safety management approach—small vehicles offer flexibility and convenience, while large vehicles are subject to stricter controls. The regulations clearly define these differences, and drivers must comply to avoid complications.
