N.D. Cent. Code § 39-20-13
In cases of death resulting from a motor vehicle accident or other unnatural death occurring in a motor vehicle, the county coroner shall require that specimens of blood, urine, and vitreous humor be withdrawn from the body of the decedent within twenty-four hours after the decedent's death by a coroner, coroner's physician, or other qualified person, prior to embalming. The specimens must be collected and preserved by methods and techniques established by the director of the state crime laboratory or the director's designee. The specimens so drawn must be sent to the director of the state crime laboratory or the director's designee for analysis for alcohol, carbon monoxide, and other drug content. The director of the state crime laboratory or the director's designee shall keep a record of all such examinations to be used for statistical purposes. The records must be made available to the director for use by the national highway traffic safety administration in analyzing fatal accidents. The information in the possession of the director may be obtained from the director of the state crime laboratory or the director's designee only as provided in this section. Except as provided, the results of the examinations referred to in this section must be used only for statistical purposes, except that the results must be released upon the issuance of a subpoena duces tecum by a court of competent jurisdiction in any civil or criminal action. The cumulative results of the examinations, without identifying the individuals involved, must be disseminated to interested state and local officials and made public by the director of the state crime laboratory or the director's designee. Any person drawing the specimens and any person making any examination under the terms of this section are immune from all liability, civil or criminal, that might otherwise be incurred or imposed.
