Missouri’s open container law is one of the most permissive in the country. Under Section 577.017 of the Missouri Revised Statutes, only the driver is barred from drinking alcohol while the vehicle is moving. 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 car.
What the Statute Actually Prohibits
The law is narrow. Section 577.017 makes it illegal to consume any alcoholic beverage while operating a moving motor vehicle on a public road, whether that’s a state highway, a county road, a city street, or an alley.1Missouri Revisor of Statutes. Missouri Code Title XXXVIII – Chapter 577 – Section 577.017 The prohibited act is the driver drinking while the car is in motion. That’s the whole rule.
What the statute does not do is just as important. It does not ban possession of open containers in the passenger area. It does not apply to parked vehicles. And it does not apply to passengers. A stopped car at a red light is technically not being “operated” in motion, but relying on that distinction during a traffic stop is a bad idea.
Passengers Can Legally Drink
Missouri is one of only six states where the open container law does not reach passengers.2National Conference of State Legislatures. Open Container and Consumption State Statutes An adult passenger can pour and drink from an open container while riding down a Missouri road without breaking state law. Nothing in the statute requires the container to be stored in a specific part of the vehicle.
This surprises visitors from stricter states, where any open container anywhere in the passenger area is a violation. Missouri didn’t go that far. A sober driver can transport friends who are drinking, and no one in the car is committing a state offense.
Penalty for a Driver Who Drinks While Driving
A driver caught drinking behind the wheel of a moving car faces an infraction, the lowest tier of offense in Missouri. The statute states that the violation “shall not be reflected on any records maintained by the department of revenue,” so it doesn’t appear on your state driving record and adds no state-level points to your license.1Missouri Revisor of Statutes. Missouri Code Title XXXVIII – Chapter 577 – Section 577.017
Municipalities are a different story. Many Missouri cities have their own open container ordinances, and a municipal conviction can add two points to your driving record even when the state infraction would not.3MO.gov. Missouri Driver Record Traffic Violation Descriptions and Points Assessed Where you’re cited and under which law decides whether your record takes the hit.
Drinking while driving is also not the same thing as driving while intoxicated. If an officer sees a driver drinking, the 577.017 infraction is likely the smallest problem in the traffic stop. It hands the officer probable cause to investigate further, and a blood alcohol content of .08% or higher turns the encounter into a full DWI case with much heavier consequences.
Taking Unfinished Wine Home From a Restaurant
Missouri carves out a specific rule for partially consumed wine. Under Section 311.101, you can leave a restaurant with an unfinished bottle of wine if all four of these conditions are met:4Missouri Revisor of Statutes. Missouri Revised Statutes Section 311.101
- The wine was served with a meal.
- The bottle was partially consumed. You can’t have a sealed bottle bagged for takeout.
- The restaurant provides a dated receipt covering the unfinished wine.
- The restaurant reseals the bottle in a one-time-use, tamperproof, transparent bag before you leave.
As long as the bag stays sealed and you keep the receipt during transport, the wine isn’t treated as an open container. Tear the bag open in the car and that protection is gone.
Where the Permissive Rule Stops
The relaxed vehicle rules don’t mean anything goes. A few boundaries matter.
Courthouses, Churches, and Schools
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, or in any courthouse.5Missouri Revisor of Statutes. Missouri Revised Statutes Section 574.075 A Class B misdemeanor is considerably more serious than the vehicle-consumption infraction.
Local Ordinances
Cities and counties add their own layer. Individual municipalities restrict open containers in parks, on sidewalks, near schools, and in other public spaces, and the rules vary widely from one town to the next. What’s legal in one city can draw a citation in the next. When in doubt about a particular location, the local code is what controls.
Entertainment Districts
Section 311.086 lets cities designate entertainment districts where people can carry drinks purchased from licensed establishments through common outdoor areas and into other licensed businesses within the boundaries.6Missouri Revisor of Statutes. Missouri Revised Statutes Section 311.086 Kansas City’s Power and Light District and parts of downtown St. Louis are the best-known examples. Cross the posted boundary or drink outside the posted hours and the permission ends.
Commercial Drivers
The permissive state rules do not extend to commercial motor vehicles. Federal regulation 49 CFR 392.5 bans commercial drivers from using or possessing alcohol while on duty or operating a commercial vehicle, prohibits consumption within four hours of going on duty, and treats any detectable presence of alcohol on duty as a violation.7eCFR. 49 CFR 392.5 – Alcohol Prohibition A driver in violation is placed out of service for 24 hours. The only possession exceptions are alcohol carried as a manifested shipment and alcohol held by bus passengers. Missouri enforces the federal rule, so the state’s lenient passenger-car law is irrelevant behind the wheel of a commercial truck.
