Laws in each state generally require a person to be 21 years of age or older to possess alcoholic beverages. Some states make limited exceptions, such as when underage persons have parental permission and are on private property. The penalties for this offense known as a minor in possession (MIP) or possession of alcohol under the legal age (PAULA) vary from state to state. All 50 states and the District of Columbia also have laws that require a person to be 21 years of age or older to purchase alcoholic beverages.
In Montana, the legal age for possession and purchase of alcoholic beverages is 21 years old, in line with federal law and the laws of all 50 states. Montana does provide for some exceptions to this rule. Underage persons may possess alcoholic beverages if they are on private property with the permission of their parents or guardians, and the parents or guardians are present. However, these exceptions do not permit the consumption of alcohol by minors. Penalties for minor in possession (MIP) offenses can include fines, community service, mandatory attendance in an alcohol education program, and driver's license suspension. The severity of the penalties often depends on the number of prior offenses. It's important to note that local ordinances may also have additional regulations and penalties regarding underage possession of alcohol.
