Dual license plate refers to the Hong Kong license plate applied for by vehicles in mainland China. Blue license plate: white characters on a blue background with white borders. This type of license plate is installed on trucks with a total weight below 4,500KG (excluding) and vehicles with seating capacity of 20 people or less and a body length below 6 meters (excluding). It is used for passenger and cargo vehicles below medium size and special purpose vehicles. Yellow license plate: black characters on a yellow background with black borders, used for medium-sized and above passenger and cargo vehicles and special purpose vehicles; semi-trailer tractors; electric vehicles. Yellow plate vehicles generally refer to large vehicles, such as trucks over 2 tons or buses (including vans with 10 seats or more).

The term "Shuang Pai" in the automotive world typically refers to an illegal practice where a vehicle uses another vehicle's license plate to operate, commonly known as a "cloned plate car." Having driven for decades, I've seen many such cases. For instance, some people use cloned plates to evade tickets or insurance costs, only for the real owner to suffer unjustly—buried under fines and forced to prove their innocence at the traffic bureau. Cloning methods vary, from buying fake plates to swapping them onto wrecked cars; they may look identical, but the actual vehicle identification numbers differ. Traffic authorities frequently crack down on such vehicles, with severe fines or even criminal charges if caught. So, it's crucial to safeguard your vehicle documents, regularly verify your car's details, and avoid falling victim. Cloned plates are often found in older neighborhoods or used car markets—I recommend joining community groups and staying vigilant.

Double license plates mainly refer to the illegal use of two license plates on a vehicle, most commonly seen in cloned vehicles impersonating others' information. From a safety perspective, this issue poses significant risks. In the event of an accident, the fake-plate vehicle may flee, leaving the actual owner potentially liable. Traffic regulations have zero tolerance for such fraud. For example, if caught domestically, the vehicle may be impounded, heavily fined, and criminal charges may be pursued. I personally experienced the hassle when a friend's car was cloned and received a traffic violation notice from another location, which was time-consuming, exhausting, and disrupted daily travel. In cross-border regions, there are legally permitted dual license plates, such as vehicles with Yue Z plates in Shenzhen and Hong Kong plates, but these are government-approved convenience measures requiring formal applications. To prevent problems, car owners should regularly check that the engine number matches the records, and when purchasing used cars, it's essential to verify the vehicle's history.

Double plates usually mean a vehicle is illegally driving under another license plate, which is a serious case of plate fraud. The identification method is simple: compare whether the vehicle's VIN code or chassis number matches. If they don't match, it may be a fake plate. Traffic enforcement often checks for these on the road, and if problems are found, the vehicle will be towed. Using fake plates can lead to increased fines, affect insurance, and other troubles. It is recommended that car owners regularly check the integrity of their license plates and verify the vehicle's registration status through apps or websites. Avoiding involvement in such issues ensures peace of mind on the road.
