Vehicle management office, the full name of the vehicle management office, is mainly responsible for the registration, change, transfer, mortgage and cancellation of motor vehicles. The vehicle management office applies for, supplements, redeems, verifies and accepts other businesses related to motor vehicles and drivers.

Every motor vehicle and driver's license business post in the DMV has the obligation to supervise the work of the last post. If it is found that the procedures handed in at the last post are in doubt, or the business is handled in violation of regulations, the documents and forms are not standardized, and they are not signed and sealed as required, they should report to the supervision post. The post of supervisor should be investigated and handled immediately, and the handling records should be made.
