If I am under the age of 21 years and choose to drink alcohol while visiting Mexico, can I get arrested when I come back to the United States?
Yes, the legal age for drinking alcohol in Arizona is 21 years old. In addition, Arizona laws forbid any person under the age of 21 years to operate or be in actual physical control of a motor vehicle while there is any spirituous liquor in the person's body. A conviction for Underage DUI is a misdemeanor criminal conviction.
