Okla. Stat. tit. 47 § 580.2
During the time a person is operating a motor vehicle or powersports vehicle with the express or implied permission of a new motor vehicle or new powersports vehicle dealer, as defined in Section 562 of this title, such person's motor vehicle liability policy shall have primary coverage with the motor vehicle liability policy of the dealer having secondary coverage until the vehicle is returned. As used herein, "motor vehicle liability policy" means motor vehicle insurance against legal liability for the death, injury, or disability of any human being, or for damage to real or personal property. The motor vehicle liability policy of any person who has been loaned a motor vehicle or powersports vehicle by a dealer pursuant to the terms of this section shall provide primary coverage for any death or injury of any human being or for any real or personal property damage, including damage to the loaned vehicle, with the motor vehicle insurance policy of the dealer having secondary coverage for any death or injury of any human being or for any real or personal property damage, including damage to the loaned vehicle. The change in financial responsibility shall be evidenced by a release signed by the person operating the vehicle with the express or implied permission of the dealer with the release to be returned to the person upon the return of the motor vehicle or powersports vehicle to the dealer. The motor vehicle liability policy of such person shall meet the minimum financial responsibility requirements found in Section 7-324 of this title.
This section shall apply only to the loan of a motor vehicle or powersports vehicle by a new motor vehicle or new powersports vehicle dealer which occurs without financial remuneration in the form of a fee or lease charge.
