Arizona’s Open Container Law, Explained

What the law prohibits

Under A.R.S. § 4-251, it is unlawful to possess an open container of spirituous liquor within the passenger compartment of a motor vehicle on a public highway or right-of-way — and unlawful to consume alcohol there. “Open” includes any broken seal, and the rule reaches both the driver and any passenger with the container. It is a class 2 misdemeanor: up to four months in jail and a $750 fine plus surcharges, though fines are the typical outcome.

The exceptions that matter

• The trunk, a locked glove compartment, or — in a vehicle without a trunk — the area behind the last upright seat
• Passengers in the living quarters of a motorhome
• Passengers in vehicles licensed to carry passengers for hire, such as limousines and taxis

The practical rule: an opened bottle you are transporting home belongs in the trunk, sealed as well as it can be. The passenger-compartment line, not intent, is what the statute draws.

Where it usually shows up: next to a DUI

Open container counts commonly appear as add-on charges after a stop that becomes a DUI investigation — and sometimes they are what remains when the DUI itself cannot be proven. The container is also evidence the defense examines: whose was it, where exactly was it, and did the search that found it hold up. Those questions have real answers, and they are worth asking before pleading to anything.
