Okla. Stat. tit. 26 § 7-123.1
When any voter states that he or she is able to reach the location of the polling place, but because of a physical disability or infirmity other than visual is unable to enter the election enclosure, the inspector shall administer an oath to the voter in which the voter shall swear to or affirm the fact of such disability or infirmity. Should a voter so qualify himself or herself, it shall be the duty of two (2) precinct officials, of different political parties, to give the voter such assistance as needed in voting. Such assistance shall afford as much privacy to the voter in marking ballots as is practical. The precinct officials assisting in such voting shall make a written record of the circumstances involved.
