Okla. Stat. tit. 47, § 1137.3
The purchaser of every new motor vehicle, travel trailer or commercial trailer shall register or license the same within thirty (30) days from the date of purchase. It shall be the responsibility of the selling dealer to place a temporary license plate, in size similar to the permanent Oklahoma license plate but of a fibrous substance, upon a new motor vehicle, travel trailer or commercial trailer when a transaction is completed for the sale of said vehicle or trailer. Said temporary license plate shall show the dealer's license number which is issued to him or her each year by the Oklahoma Tax Commission, the date the new motor vehicle, travel trailer or commercial trailer was purchased and the company name of the selling dealer. On or before thirty (30) days from the date of purchase of a new motor vehicle, travel trailer or commercial trailer, said temporary license plate shall be removed and replaced with a permanent, current Oklahoma license plate. Use of said temporary license plate by a licensed dealer for other than the purpose of normally doing business shall constitute grounds for revocation of the dealer's license.
It shall be unlawful for any licensed dealer of new motor vehicles, travel trailers or commercial trailers to procure the registration and licensing of any new motor vehicle, travel trailer or commercial trailer sold by such licensed dealer or to act as the agent for such purchaser in the procurement of said registration and licensing. The license of any licensed dealer of new motor vehicles, travel trailers or commercial trailers violating the provisions of this section shall be revoked.
