In most states, keeping an open container of alcohol in your trunk is legal. Open container laws target the passenger area of the vehicle, and the trunk sits outside that boundary. Roughly 39 states and the District of Columbia follow a federal framework that bans open alcoholic beverages from the passenger area but treats the trunk as an acceptable storage location.1NHTSA. Open Container Laws A locked container works similarly in many places. What matters is the wall between you and the alcohol.
What Counts as an Open Container
Under federal law, an “open alcoholic beverage container” is any bottle, can, or other receptacle that contains any amount of alcohol and is either open, has a broken seal, or has had some of its contents removed.2Office of the Law Revision Counsel. 23 US Code 154 – Open Container Requirements A recorked bottle of wine from dinner. A flask with the cap off. A half-finished six-pack with one can missing. All of them qualify. The container doesn’t need to be in anyone’s hand; simply having it in the wrong part of the vehicle is enough.
Empty containers are a gray area. The federal definition requires that the receptacle “contain any amount of alcoholic beverage,” which technically excludes a bone-dry bottle. In practice, proving a container is truly empty during a traffic stop is a hard sell, and officers often treat empties as evidence of recent consumption. Tossing finished cans in the trunk rather than leaving them on the back seat avoids an unnecessary conversation.
Why the Trunk Is the Safe Spot
The whole concept hinges on one boundary: the passenger area. Federal regulations define that area as the space designed to seat the driver and passengers while the vehicle is in operation, plus any area readily accessible to them from their seating positions, including the glove compartment.3eCFR. 23 CFR Part 1270 – Open Container Laws Front seats, back seats, door pockets, center console, and an unlocked glove box are all off-limits for open alcohol.
The trunk falls outside this definition because you can’t reach it from any seat while the car is moving. For a standard sedan with a separate, enclosed trunk, storing an open container there is the cleanest way to transport it legally.
An unlocked glove compartment counts as part of the passenger area under the federal standard, even when closed. A locked glove compartment is a different story: federal compliance criteria treat a locked container as an acceptable alternative, similar to a trunk.3eCFR. 23 CFR Part 1270 – Open Container Laws Whether your state follows that distinction depends on local law.
Vehicles Without a Trunk
SUVs, hatchbacks, minivans, and pickup trucks have no sealed-off trunk space. Federal compliance criteria account for this by allowing states to permit open containers “behind the last upright seat” or “in an area not normally occupied by the driver or a passenger” in vehicles without a trunk.3eCFR. 23 CFR Part 1270 – Open Container Laws Most compliant states follow this approach.
- In an SUV or hatchback, place the open container in the cargo area behind the rear seats. A retractable cargo cover adds a layer of protection against an officer’s judgment call about “readily accessible.”
- In a pickup truck, the bed itself is outside the passenger area. A locked toolbox in the bed is even better.
- In a minivan, behind the last row of seats. If you’ve folded the third row flat, the area may no longer be clearly “behind” a seat, and the analysis gets murkier.
A locked container inside the vehicle is another option in many jurisdictions. That could be a lockbox, a locked cooler, or a locked glove compartment. The key word is “locked.” A zipped bag or closed cooler without a lock doesn’t satisfy the requirement.
States That Don’t Follow the Federal Standard
Not every state adopted the federal framework. Roughly eight states allow passengers to possess open containers of alcohol, including Alaska, Connecticut, Delaware, Mississippi, Missouri, Rhode Island, Tennessee, and Virginia. The laws vary widely. Some let passengers hold open containers while still barring the driver; others have minimal restrictions overall. Mississippi is the most permissive example, with no statewide open container law for passengers, though individual cities may have local ordinances. Virginia allows passenger possession but treats the presence of an open container as a factor that can affect the driver during a DUI investigation.
These state-level differences are exactly why the trunk remains the safest default even where the law is looser. An open container on the back seat might be technically legal, but it gives law enforcement a reason to look more closely at the driver.
Who Gets the Ticket
In states that comply with the federal standard, the prohibition applies to everyone in the vehicle, driver and passengers alike.2Office of the Law Revision Counsel. 23 US Code 154 – Open Container Requirements If a passenger is holding a beer, both the passenger and the driver can face a citation depending on how the state structured its law. Some states ticket only the person in possession; others treat the driver as responsible regardless of who owns the drink.
This is where open container laws create real friction. A designated driver doing everything right can still pick up a violation because a friend cracked open a can in the back seat. Make the rule clear before anyone gets in the car: open drinks go in the trunk or stay at the party.
What a Violation Actually Costs
A first-time open container violation is typically an infraction or low-level misdemeanor. Fines generally range from $25 to $500, and court costs or administrative surcharges can add substantially to the total. Jail time is rare for a standalone first offense, though it exists on the books in some jurisdictions.
The fine itself is often the smaller problem. Open container violations can raise car insurance premiums by an average of roughly 44%, and some insurers move more aggressively. That increase typically lasts three to five years, so a $100 fine can turn into thousands in added premiums over time.
An open container also becomes far more serious when it appears alongside other charges. In many states, an open container in the vehicle during a DUI stop can enhance the penalties for the impaired driving charge, meaning higher fines, longer license suspensions, or mandatory minimum sentences. Even if you’re under the legal limit, the open container gives prosecutors additional leverage.
Restaurant Wine and the Recorked Bottle
Many states have adopted a “restaurant wine” or “doggy bag” exception that lets you take home a partially consumed bottle of wine. The typical requirements are that the bottle was purchased with a meal, the restaurant resealed it (usually with a tamper-evident cap or shrink wrap), and the sealed bottle goes in the trunk for transport. States that allow resealed containers can still comply with federal open container standards, provided the recorking process meets specific criteria.4APIS – Alcohol Policy Information System. Variables: Transportation – Open Containers of Alcohol in Motor Vehicles
Put the resealed bottle in the trunk immediately, even if your state’s exception might technically allow it elsewhere. In an SUV or hatchback without a trunk, place it behind the last row of seats in a bag. The point of the exception is to get the bottle home legally, nothing more.
