Under Missouri’s open container law, only the driver is prohibited from drinking alcohol while a vehicle is moving on a public road. Passengers can legally hold and drink from an open bottle or can, and there is no state rule requiring open containers to be stored in the trunk or anywhere else in the vehicle. Missouri is one of about six states that chose not to extend its open container rule to passengers.1National Conference of State Legislatures. Open Container and Consumption State Statutes
What the Statute Actually Says
Section 577.017 of the Missouri Revised Statutes makes it an infraction for a person to consume any alcoholic beverage while operating a moving motor vehicle on a public road, including state highways, county roads, city streets, and alleys.2Missouri Revisor of Statutes. Missouri Code Title XXXVIII – Chapter 577 – Section 577.017 The law targets one act: the driver drinking while the car is in motion.
What the statute does not do is as important as what it does. It does not ban mere possession of an open container in the vehicle. It does not apply to a parked car. And it does not reach passengers at all.
Passengers and Open Containers
An adult passenger in Missouri can legally hold, pour, and drink from an open container of alcohol while the car is on a public road. Nothing in state law requires those containers to be stored in a specific area, kept sealed, or hidden from view.
This surprises people from stricter states, where open containers are banned anywhere in the passenger compartment regardless of who is drinking. In practice, a sober driver in Missouri can transport friends who are drinking without anyone in the car breaking state law. Local ordinances can still change that answer, so the city you are driving through matters.
What Happens If the Driver Gets Caught
A violation of Section 577.017 is an infraction, the lowest level of offense in Missouri. The statute specifically provides that the violation “shall not be reflected on any records maintained by the department of revenue,” so a state-level conviction does not appear on your driving record or add points to your license.2Missouri Revisor of Statutes. Missouri Code Title XXXVIII – Chapter 577 – Section 577.017
A municipal open container ticket is different. A conviction under a city ordinance can result in two points assessed against your driving record even though the state infraction does not.3MO.gov. Missouri Driver Record Traffic Violation Descriptions and Points Assessed Which law the officer writes the citation under decides whether your record takes a hit.
Drinking behind the wheel also gives an officer probable cause to look further. If your blood alcohol content is at or above .08%, the open container issue becomes a footnote to a DWI charge, which carries far more serious consequences than the infraction itself.
Where Drinking Is Still a Crime
Missouri’s relaxed vehicle rule does not make alcohol welcome everywhere. Section 574.075 makes it a Class B misdemeanor to drink alcohol, or to appear intoxicated and disorderly, in a schoolhouse or church during an assembly of people, or in any courthouse.4Missouri Revisor of Statutes. Missouri Revised Statutes Section 574.075 A Class B misdemeanor is a far more serious matter than the vehicle infraction.
Cities and counties also set their own rules on open containers in parks, on public sidewalks, near schools, and in other public spaces. These vary widely across the state. What is lawful on one side of a city line can draw a citation on the other, so the local municipal code is the one that controls when you step out of the car.
Entertainment Districts
Section 311.086 allows cities to create entertainment districts where people may carry alcoholic beverages purchased from licensed establishments into common outdoor areas and into other licensed businesses within the district.5Missouri Revisor of Statutes. Missouri Revised Statutes Section 311.086 The district’s promotional association sets the boundaries, days, and hours.
The Power and Light District in Kansas City and parts of downtown St. Louis operate under this provision. You can walk between bars and restaurants with a drink in hand so long as you stay inside the posted boundaries and within posted hours. Step outside the district with the drink and the exemption is gone.
Taking Unfinished Wine Home From a Restaurant
Section 311.101 lets you leave a restaurant with a partially consumed bottle of wine as long as four conditions are met:6Missouri Revisor of Statutes. Missouri Revised Statutes Section 311.101
- The wine was served with a meal, not purchased on its own at a bar.
- The bottle was partially consumed at the restaurant; a sealed bottle cannot be bagged for takeout.
- The restaurant provides a dated receipt covering the unfinished wine.
- The restaurant places the bottle in a one-time-use, tamperproof, transparent bag and seals it before you leave.
Keep the receipt and the sealed bag intact during the drive home. Breaking the seal in the car turns the bottle back into an open container.
Commercial Drivers Are a Different Story
None of the permissive passenger-vehicle rules apply behind the wheel of a commercial motor vehicle. Federal regulation 49 CFR 392.5 bars commercial drivers from using or possessing alcohol while on duty or operating a commercial vehicle, and from consuming alcohol within four hours of going on duty. Any detectable presence of alcohol while on duty is a violation.7eCFR. 49 CFR 392.5 – Alcohol Prohibition
A driver found in violation is placed out of service for 24 hours, must report the violation to the employer within 24 hours, and must notify the licensing state within 30 days. The possession ban has narrow exceptions for alcohol hauled as a manifested shipment and alcohol in the possession of bus passengers. Missouri enforces these federal rules, so a commercial driver gets none of the leeway that applies in a personal car.
