Why Are There Differences Between Yellow and Blue License Plates for Motorcycles?

[VanHailey]

The differences between blue and yellow license plates for motorcycles are as follows: Yellow Plate: Motorcycles with an engine displacement above 50CC are required to have a yellow license plate; those with a displacement of 50CC or below are classified as light motorcycles and must have a blue license plate. Yellow-plated motorcycles require the rider to hold a valid motorcycle license (Class E). According to regulations, a yellow-plated motorcycle can carry a maximum of two people, including the rider. Blue Plate: Blue-plated two-wheeled motorcycles are categorized as light motorcycles and also require the rider to hold a valid license (Class F). Blue-plated motorcycles are restricted to carrying only one person, meaning the rider cannot have a passenger. Article 95 of the 'Road Traffic Safety Law of the People's Republic of China' stipulates: If a motor vehicle driven on the road does not display a license plate, fails to carry an inspection compliance mark or insurance mark, or does not have the vehicle registration certificate or driver's license on board, the traffic management department of the public security organ shall impound the vehicle, notify the party to provide the corresponding license, mark, or complete the required procedures, and may impose penalties in accordance with Article 90 of this law. Once the party provides the corresponding license, mark, or completes the required procedures, the vehicle shall be promptly returned.

Last time I accompanied my friend to buy a car, I finally understood this issue. Yellow plates and blue plates are mainly divided by engine displacement. Blue plates are usually for small motorcycles under 50cc, considered lightweight motorcycles, which are slower and more fuel-efficient, requiring an F license to ride. Yellow plates are for ordinary motorcycles above 50cc, such as common 125cc or 250cc models, which require this type of plate and an E license to ride. Road access also differs in many cities—blue plates are often restricted from elevated roads or main thoroughfares, while yellow plates can generally go anywhere. However, recently some areas have started adjusting policies, such as implementing more detailed management under the new national standards for electric vehicles. Understanding the different plates can help avoid fines when riding on the road.

Last year when I was learning to drive, the instructor mentioned this. Simply put, the country categorizes motorcycles into two types for management. Small-displacement blue-plate motorcycles are easier to operate and cheaper to maintain, making them particularly suitable for students or elderly people for short trips like grocery shopping. Yellow-plate motorcycles have much more power and are more stable for long-distance travel, but they cost several hundred yuan more each year in insurance and vehicle tax. The key is to consider the type of roads you'll be riding on. For someone like me, who lives in the suburbs and needs to commute into the city, I chose a yellow-plate motorcycle that can ride on expressways. I heard some places also consider power parameters, so it's safest to check local regulations before buying a motorcycle.

Once while queuing at the DMV, I overheard staff discussing that it mainly depends on engine specifications. Blue-plate vehicles generally have displacements under 50cc, with a maximum speed limit of 50 km/h, and are much lighter in weight. Yellow-plate vehicles offer significantly better performance, capable of highway speeds and carrying passengers. License requirements also vary by region - for instance, my cousin just obtained an E-class license to ride his yellow-plate Kawasaki. In practical use, fuel costs don't differ much, but blue-plate vehicles are far more convenient for navigating narrow alleys.

Last time at the car club meetup, we discussed this and found significant regional differences. In big cities like Beijing, Shanghai, and Guangzhou, yellow-plate motorcycles face fewer restrictions but the license fees are shockingly expensive, while blue plates are more common in suburban areas. In small towns, no one really enforces the rules, and many 125cc bikes run with blue plates. The key difference lies in engine power – for example, national standards require yellow plates for engines exceeding 4 kilowatts. For daily use, blue-plate bikes are indeed much more convenient, especially when parking spaces in residential areas are tight, as lightweight motorcycles can squeeze into any available spot.

Veterans on motorcycle forums have analyzed this issue, and the essence lies in traffic management needs. Blue-plated vehicles have looser regulations, such as no mandatory annual inspections, which is why many electric mopeds use this type of plate. Yellow-plated vehicles are classified as motor vehicles and subject to strict management, including different accident liability divisions. I believe the choice mainly depends on usage scenarios. If you only need to run errands around the neighborhood, a small blue plate is cheap and convenient enough. But if you frequently ride on provincial highways or enjoy weekend motorcycle trips, the power and stability of a large yellow plate become far more important.
