Montana’s Open Container Laws

What Does Montana’s Open Container Law Actually Say?

Montana Code Annotated § 61-8-460 makes it illegal for any person in a motor vehicle on a public highway or adjacent right-of-way to possess an open alcoholic beverage container. This law applies to drivers and passengers, and it does not matter whether the beverage is being actively consumed.

The law defines an “open container” as any bottle, can, orother receptacle:

• That has been opened,
• That has a broken seal, or
• From which part of the contents has been removed.

It’s important to emphasize that mere possession is enough for a violation—even if you’re not drinking it.

Where Open Containers Are Prohibited

The open container law applies to:

• Public highways and county roads
• Vehicles in motion and vehicles temporarily stopped or parked
• The passenger compartment of a car, truck, or SUV

In practice, this means any alcoholic beverage—beer, wine, liquor… Whether it’s in a cup holder, door pocket, or even a backpack on the seat.

Where Open Containers Can Be Legally Stored

The law provides exceptions for storage of alcohol in are as that are not accessible from the passenger area. Legal options include:

• The trunk of a car
• The bed of a pickup truck
• Behind the last upright seat in a vehicle without a trunk (like an SUV or hatchback)

In other words, if law enforcement determines that the container was reachable by anyone in the vehicle, that’s enough to issue a citation.

Exceptions to the Rule

Montana law recognizes limited exceptions, such as:

• Passengers in a for-hire vehicle like a limousine or party bus (not a standard Uber or Lyft)
• Living quarters of a motorhome or recreational vehicle (RV)

In these cases, alcohol may be lawfully consumed by passengers, but the driver is still prohibited from possessing or accessing open alcohol while driving.

Additionally, special alcohol permits may apply in public parks or trails managed by cities like Missoula, but these are location-specific and must be obtained through the proper channels.

What Happens If You’re Cited?

A violation of Montana’s open container law is a misdemeanor traffic offense. Penalties typically include:

• A fine of up to $100
• Possible points on your driving record
• Probable cause for a DUI investigation, if officers observe additional signs of impairment

While this may not result in jail time, the consequences can add up—especially if you’re on probation, hold a commercial driver’s license, or are under the legal drinking age.

Why This Matters

Open container citations are often underestimated. But they can have broader implications:

• They may complicate DUI charges, especially if field sobriety tests or breath tests follow the stop.
• They can be used to justify searches of your vehicle, leading to additional charges.
• For repeat offenders or minors, they may trigger harsher penalties or driver’s license suspensions.

At Ryan, Miller & Coburn, we’ve seen open container charges used as leverage in DUI cases, college conduct hearings, and probation violations. One bad judgment call shouldn’t define your record or future.

What To Do If You’ve Been Charged

If you’re facing an open container citation—or if it’s part of a broader DUI arrest—it’s critical to speak with a knowledgeable defense attorney right away. Our team at Ryan, Miller & Coburn will:

• Evaluate whether the stop and search were lawful
• Examine the facts of the case to challenge the citation
• Work to minimize fines, preserve your driving record, and protect your future

Meanwhile in Butte…
While Missoula’s alcohol-in-parks rules might feel strict (yes, there are permits, trail restrictions, and entire parks where alcohol is completely banned), we’re not the only Montana city drawing clearer lines around public drinking.

Butte-Silver Bow commissioners voted 7–5 to approve a new public drinking ordinance—banning open containers and public alcohol consumption between 2 a.m. and 8 a.m. This is a major shift for Butte, long known as one of the only places in the country without restrictions on public drinking.

At the final vote, Chief Executive Matt Vincent urged commissioners to move forward, saying, “Enough is enough. We have too many tremendous opportunities in front of us to spend any more time or energy on this.” He even acknowledged that he had once considered sending the issue to a public vote, but changed his mind due to rising concerns, bad press, and advice from outside leadership.

The ordinance goes into effect 30 days after the vote onNovember 20, meaning that starting December 20, public drinking in Butte will only be allowed during daytime and evening hours. After 2 a.m., if you’re still partying in public, it could cost you.

So why does this matter for Missoula? Because local lawson public drinking are changing across the state—even in places you’d never expect. This week, as we dig deeper into Missoula’s alcohol permit system and what’s allowed in our parks and trails, Butte’s move is a reminder: knowing the rules helps you stay safe, respectful, and fine-free.

Final Thoughts

While Montana prides itself on its independent spirit, open container laws are clear—and strictly enforced. Keeping alcohol out of the cabin of your vehicle is the simplest way to avoid a costly mistake. And if you do find yourself facing charges, know that you don’t have to navigate the legal system alone.
