The new "Regulations" simplify the procedures for handling license plates, including shortening the time limit of half-way license plates, expanding the scope of restarting license plates, and improving the selection method of motor vehicle license plates.

The new "regulations" require shortening the time limit for handling licenses. For those who issue legal and valid certificates and vouchers, the time limit for motor vehicle registration will be shortened from 5 days to 2 days. When applying for the replacement of motor vehicle registration certificate, the replacement time limit will be shortened from 15 to 1 day.

The new "Regulations" cancelled the examination and approval procedures for change registration. If it is necessary to change the body color or replace the body, the owner will not apply to the vehicle management office in advance, and can directly register the change. The revised "Regulations" expanded the scope of reusing the license plate number, from the original limited to scrapped motor vehicles to all motor vehicles that have been cancelled or transferred for registration, so as to meet the needs of car owners to retain the original license plate number.
