I didn't know what the open container law was in Missouri until I looked it up.
What Is the Missouri Open Container Law? Missouri doesn't have a statewide open container law, making it legal for non-driving passengers, who are 21-years-old or older, to have an open container and drink while in the car.Mar 25, 2022
That is NOT the case in my home state- Kansas.
Transporting open containers of alcoholic beverages where they are accessible to the driver or passengers is a misdemeanor violation of state law. A conviction will result in a fine of up to $200 and a maximum six months in jail.
