When a person has volunteered for admission pursuant to § 37.2-814 or been ordered to be admitted to a facility under §§ 37.2-815 through 37.2-821, the judge or special justice shall determine after consideration of information provided by the person’s treating mental health professional and any involved community services board or behavioral health authority staff regarding the person’s dangerousness, whether transportation shall be provided by the sheriff or may be provided by an alternative transportation provider, including a family member or friend of the person, a representative of the community services board, a representative of the facility at which the person was detained pursuant to a temporary detention order, or other alternative transportation provider with personnel trained to provide transportation in a safe manner. If the judge or special justice determines that transportation may be provided by an alternative transportation provider, the judge or special justice may consult with the proposed alternative transportation provider either in person or via two-way electronic video and audio or telephone communication system to determine whether the proposed alternative transportation provider is available to provide transportation, willing to provide transportation, and able to provide transportation in a safe manner. If the judge or special justice finds that the proposed alternative transportation provider is available to provide transportation, willing to provide transportation, and able to provide transportation in a safe manner, the judge or special justice may order transportation by the proposed alternative transportation provider. In all other cases, the judge or special justice shall order transportation by the sheriff of the jurisdiction where the person is a resident unless the sheriff’s office of that jurisdiction is located more than 100 road miles from the nearest boundary of the jurisdiction in which the proceedings took place. In cases where the sheriff of the jurisdiction of which the person is a resident is more than 100 road miles from the nearest boundary of the jurisdiction in which the proceedings took place, it shall be the responsibility of the sheriff of the latter jurisdiction to transport the person. If the judge or special justice determines that the person requires transportation by the sheriff, the person may be delivered to the care of the sheriff, as specified in this section, who shall transport the person to the proper facility. In no event shall transport commence later than six hours after notification to the sheriff or alternative transportation provider of the judge’s or special justice’s order. If any state hospital has become too crowded to admit any such person, the Commissioner shall give notice of the fact to all community services boards and shall designate the facility to which sheriffs or alternative transportation providers shall transport such persons. If an alternative transportation provider providing transportation of a person becomes unable to continue providing transportation of the person at any time after taking custody of the person, the primary law-enforcement agency for the jurisdiction in which the alternative transportation provider is located at the time he becomes unable to continue providing transportation shall take custody of the person and shall transport the person to the proper facility. No person who provides alternative transportation pursuant to this section shall be liable to the person being transported for any civil damages for ordinary negligence in acts or omissions that result from providing such alternative transportation.
