Yellow license plate vehicles can be registered. The reasons why the traffic management 12123 app cannot register a vehicle are: Information Delay: After purchasing a new car, there might be a delay in information synchronization. Generally, you can check the vehicle information on 12123 after waiting for about half a month. If the vehicle information still cannot be found and registered after a long time, you should consult the staff at the vehicle management office for detailed information. Vehicle Already Bound: If the original owner has already bound the vehicle during the sale of a used car, you need to ask the original owner to unbind it before you can register it again. Exceeding the Maximum Limit of Vehicle Registrations: The requirement for vehicle registration on the traffic management 12123 app is: each user can only register 3 vehicles not under their own name, and for the same vehicle, apart from the owner, 3 other people are allowed to register it. If the number of registrations exceeds this requirement, registration will not be possible.
