I copied this from the Michigan website.
X. Responsibilities While Carrying
1. A concealed pistol licensee carrying a concealed pistol must:
? Have his or her Concealed Pistol License in possession at all times.
? Immediately disclose to a peace officer, if stopped, that he or she is carrying a concealed pistol.
? Display his or her Concealed Pistol License to a peace officer upon request.
? Display his or her driver license or Michigan personal identification card upon request.
? Not carry a concealed pistol while under the influence of alcohol or a controlled substance or while having an unlawful bodily alcohol content. However, a licensee who has consumed alcohol can legally transport a pistol if the pistol is in a locked trunk or locked compartment or container that is separated from the ammunition for that pistol.
? The licensee must have the Pistol Sales Record (RI-60) in his or her possession for the first 30 days after purchasing the pistol.
