Maine Open Container Law (2026): Statute and Exemptions

Maine makes the vehicle's operator liable, under 29-A M.R.S. § 2112-A, whenever the operator or a passenger in the passenger area possesses an open alcoholic beverage container or drinks alcohol there. As of September 2026, the exemption list and the statute's traffic-infraction status were confirmed against the state legislature's official statute site.

Jurisdiction scope: This article addresses Maine's state open container law, covering how 29-A M.R.S. § 2112-A treats the operator and passengers of a vehicle on a public way. It does not address OUI charges or boating rules. For the full 50-state comparison, see the open container laws hub; for Maine's separate OUI penalties, see Maine DUI laws.

What Maine's Open Container Law Prohibits

29-A M.R.S. § 2112-A(2), verbatim: "The operator of a vehicle on a public way is in violation of this section if the operator or a passenger in the passenger area of the vehicle: A. Consumes alcohol; or B. Possesses an open alcoholic beverage container." The person in violation is the operator, not the passenger: a passenger's drinking or possession in the passenger area is the conduct that triggers the offense, but the statute creates no separate liability for that passenger. So the driver can be cited for what a passenger does in the passenger area, even when the driver neither drank nor possessed anything. Section 2112-A(3) confirms this operator-only structure, phrasing every exception as "An operator of a vehicle is not in violation of this section if..."

What Counts as the "Passenger Area"

Maine's passenger area includes the glove compartment. That is a meaningful distinction from a handful of neighboring states in this dataset, whose statutes carve out a locked glove compartment as its own exemption; Maine's definitional clause for the passenger area does not state a comparable locked-glove-compartment exception. A reader should not assume that locking the glove box removes a container from Maine's passenger-area definition the way it does in some other states.

Exemptions

The statute exempts four situations:

• Possession, but not consumption, behind the last upright seat, or in an area not normally occupied by the driver or passengers, in a vehicle with no trunk.
• A passenger transported for a fee in a for-hire vehicle, excluding a taxicab passenger.
• A passenger in the living quarters of a motor home, trailer, semitrailer, or truck camper.
• An operator or employer holding a valid off-premise catering license, while transporting alcohol to or from a catered event.

The first exemption is narrower than it might look: it covers possession only. Consumption behind the last seat in a trunkless vehicle is not exempted by this clause.

Penalty

A violation of 29-A M.R.S. § 2112-A is a traffic infraction, not a crime. Section 2112-A itself contains no penalty subsection; the penalty comes from two other sections of Title 29-A. 29-A M.R.S. § 104 provides: "Except as otherwise provided, a person who violates a provision of this Title commits a traffic infraction." And 29-A M.R.S. § 103 provides that "A traffic infraction is not a crime," that "the penalty for a traffic infraction may not be deemed for any purpose a penal or criminal punishment," and that "the exclusive penalty for a traffic infraction is a fine of not less than $25 nor more than $500, unless specifically authorized, or suspension of a license, or both." So a § 2112-A violation carries a fine of $25 to $500, or license suspension, or both, rather than a fixed dollar amount stated in § 2112-A itself.

Federal Compliance

Federal law, 23 U.S.C. § 154, conditions a share of a state's highway funding on having an open container law that bans both possession and consumption, covers the whole passenger area, reaches every occupant, and is primarily enforced. A state that falls short has 2.5 percent of certain federal highway apportionments reserved and redirected to highway safety programs, under FHWA's annual apportionment notice. Maine is on FHWA's list of non-conforming states for fiscal year 2026 (FHWA Notice N4510.905, dated October 1, 2025), and the notice lists Maine by name without stating a reason. This page's own reading, not a confirmed FHWA finding, is that because § 2112-A charges only the operator, even for a passenger's own drinking or possession, a passenger is never individually reached the way 23 CFR 1270.4(b)(4)'s "all occupants" element appears to require, which reaches more conduct than a typical driver-only state but fewer defendants. The specific compliance gap driving Maine's inclusion on that list was not resolved in this research, and this article presents that reading as an inference, not FHWA's stated reason.
