If a specification is required in prosecutions for offenses under this title, it shall be sufficient to specify the offenses with as much certainty as to the time, place, and person as the prosecutor is able to provide, and the specifications provided may be amended at trial. When the specifications set forth the sale or furnishing of alcoholic beverages or alcohol to any unknown person or persons, the witnesses may be inquired of as to those transactions. If the name of the person is disclosed, it may be added to the specifications, and upon any terms related to postponement of the trial as the court deems reasonable. (Amended 2017, No. 83, § 103.)
