61-6-143. Self-insurers. (1) Any person in whose name more than 25 motor vehicles are registered may qualify as a self-insurer by obtaining a certificate of self-insurance issued by the department as provided in subsection (2) of this section.

(2) The department may, in its discretion, upon the application of such a person, issue a certificate of self-insurance when it is satisfied that such person is possessed and will continue to be possessed of ability to pay judgments obtained against such person.

(3) Upon not less than 5 days' notice and a hearing pursuant to such notice, the department may upon reasonable grounds cancel a certificate of self-insurance. Failure to pay any judgment within 30 days after such judgment shall have become final shall constitute a reasonable ground for the cancellation of a certificate of self-insurance.
