What is the penalty for displaying only one license plate?

[JoshuaMarie]

If a motor vehicle is driven on the road without displaying a license plate or the inspection qualification mark, the traffic management department of the public security authority shall impound the vehicle. The party involved must provide the corresponding license plate and mark, complete the necessary procedures, go to the vehicle management office to collect the license plate, and bring the relevant documents to apply for a replacement plate. After the driver submits the required procedures and pays the fine, the vehicle should be retrieved promptly.
