Legal analysis: the automobile driving license cannot be mortgaged, and the motor vehicle itself has the registration mortgage certificate, which can be registered in the vehicle management department. In addition to the public security organs, no one may temporarily detain the motor vehicle driver's license, nor have the right to detain the motor vehicle driver's license. Vehicles can apply for mortgage loans, and some banks only need to mortgage vehicle registration certificates. Different regions and banks may have different policies on automobile mortgage, depending on local banks.

Legal basis: Article 40 1 of the Civil Code of People's Republic of China (PRC). The mortgagee and the mortgagor agreed that if the debtor fails to perform the due debt before the maturity of the debt, if the collateral belongs to the creditor, it can only be paid in priority according to law.
