Okla. Stat. tit. 47, § 47-7-503: Self-insurers

(a) Any person in whose name more than twenty-five vehicles are

registered in this state may qualify as a self-insurer by obtaining

a certificate of self-insurance issued by the Department as provided

in subsection (b) of this section.

(b) 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 judgment obtained against such person.

Such certificate may be issued authorizing a person to act as a

self-insurer for either property damage or bodily injury, or both.

(c) Upon not less than five (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 thirty (30) days after such judgment shall have become final

shall constitute a reasonable ground for the cancellation of a

certificate of self-insurance.
