Drinking and driving
Missouri also has a "zero-tolerance" policy for drinking and driving for those under the age of 21. For this group, a BAC level above 0.02% is grounds for a DWI charge. The state also has enhanced suspension periods for drivers with excessive blood alcohol content, with a BAC of 0.15% or higher.
Commercial drivers are held to higher standards, with a lower legal limit of 0.04% BAC. This limit applies regardless of whether they were driving a commercial vehicle at the time of their arrest.
It is important to note that even if a driver's BAC is below the legal limit, they can still be charged with a DWI if a police officer has reason to believe they are too impaired to operate a motor vehicle safely. This includes impairment due to drugs or a combination of alcohol and drugs. Missouri's Implied Consent Law requires all drivers to comply with breath, blood, or urine testing if an officer suspects they are under the influence. Refusing to submit to these tests can result in separate administrative suspension and revocation of driving privileges.
The consequences of a DUI conviction in Missouri can be significant, including fines, license suspension, and jail time. A first or second DUI is typically classified as a misdemeanour, while a third offence is considered a felony. Certain circumstances, such as causing an accident or having a minor in the vehicle, can also elevate a DUI to a felony charge.
To avoid drinking and driving in Missouri, it is recommended to use a designated driver, public transportation, or a taxi or rideshare service. Missouri's Good Samaritan Law also provides legal protection for those who seek medical assistance for themselves or others in the event of an alcohol-related emergency.

Minors and alcohol
Missouri has a variety of laws that pertain to minors and alcohol. Firstly, the legal drinking age in Missouri is 21. It is illegal for those under 21 to consume, purchase, or possess alcohol. If a minor is caught drinking, they can be charged with a misdemeanor, fined up to $1000, and/or imprisoned for up to one year. They will also need to pay court costs and attorney fees.
The ""Abuse and Lose" law in Missouri states that a person under 21 who is found guilty of any alcohol-related traffic offense, such as possessing, consuming, or using alcohol while operating a vehicle, will have their driver's license suspended or revoked. The ""Zero Tolerance" law also applies to minors, who are not permitted to have a blood alcohol content (BAC) of more than 0.02%. If a minor is found to have a higher BAC, they are guilty of a misdemeanor and will have their driver's license suspended or revoked.
While Missouri law prohibits minors from purchasing or possessing alcohol, the law is vague regarding consumption under the supervision of a parent or guardian. Some sources interpret this to mean that minors can legally consume alcohol if it is provided by a parent or guardian and consumed on private property. However, Missouri law does not specify how much alcohol a minor can consume in this context, only stating that they should not be visibly intoxicated or have a blood alcohol content of more than 0.02%.
Minors in Missouri should also be aware of the state's open container laws. While the state has no general open container law for vehicles, allowing passengers to possess and consume alcohol while the vehicle is in motion, many municipalities have local open container laws that prohibit this.
In addition to these laws, Missouri's Good Samaritan Law provides immunity for minors who seek medical assistance for themselves or others during a drug or alcohol overdose or other medical emergency. This means that a minor experiencing or reporting such an emergency may not be arrested, charged, prosecuted, or convicted for drug or alcohol-related offenses, including minor in possession of alcohol.

Where to buy alcohol
Missouri has some of the most permissive alcohol laws in the United States. The state's historical resistance to Prohibition illustrates its longstanding relationship with alcohol commerce. Missouri is also the leading alcohol-producing state in the country, with a reputation for wine production in the Missouri Rhineland and beer production in St. Louis by Anheuser-Busch, the producer of Budweiser.
The legal drinking age in Missouri is 21. It is illegal for anyone under this age to consume, purchase, or possess alcohol. Missouri's Liquor Control Law covers any alcoholic beverage containing more than 0.5% alcohol by volume. Any beverage containing less than 0.5% alcohol by volume is exempt from all alcohol regulation, including age restrictions, and is subject only to ordinary food safety laws.
Missouri has no specific state limitations on the places where alcohol may be sold "off-premises" (for consumption elsewhere). As long as it is not located within 100 feet (30 m) of a school or church, any retail business that obtains the proper licenses from the Division of Alcohol and Tobacco Control and local authorities may sell alcohol. This includes grocery stores, drug stores, and gas stations.
Missouri does, however, limit the hours of retail alcohol sales. From Monday to Saturday, alcohol can be sold between 1:30 a.m. and 6:30 a.m. For an additional license fee, alcohol can be sold during the same hours on Sundays. Most municipalities, including St. Louis and Kansas City, have enacted local laws following this state law, prohibiting the retail sale of liquor between 1:30 a.m. and 6:30 a.m. from Tuesday to Saturday, and between midnight on Sunday and 9:00 a.m. the following morning.
Missouri has no general open container law for vehicles, a characteristic shared only with a few other states. Any non-driving vehicle passenger is permitted to possess an open container and consume alcohol while the vehicle is in motion. However, 31 smaller municipalities, including Columbia, Independence, and St. Charles, have local open container laws.
In 2005, the Missouri General Assembly passed a law allowing patrons of any "entertainment district" in Downtown Kansas City to remove any alcoholic beverage from any establishment in the district and carry it openly throughout the district, provided that the beverage is in a plastic cup marked with the logo of the establishment where it was purchased. The City Council later legalized the possession of an open container in various districts not open to vehicular traffic.
Missouri also has no dry jurisdictions, and no limitations on the interstate shipping of alcohol into the state, as long as the quantity is less than five gallons, it has been lawfully manufactured in its source jurisdiction, and it is shipped to a person who is at least 21 years of age.

Minors consuming alcohol can be charged with a misdemeanor, which can result in a fine of up to $1000 and/or up to a year of imprisonment. Additionally, minors can be charged with "minor in possession by consumption" even if they are not holding an alcohol container but have consumed alcohol.
Missouri has a "zero-tolerance" policy for drinking and driving, especially for those under 21. The legal blood alcohol concentration (BAC) limit in Missouri is 0.08%. However, for commercial drivers, the limit is lower at 0.04%. Anyone operating a vehicle with a BAC above the legal limit can be prosecuted for driving while intoxicated (DWI) and face serious consequences, including license suspension, revocation, or fines.
The state of Missouri restricts the hours for retail alcohol sales. Alcohol can be purchased from 6:00 a.m. to 1:30 a.m. daily, including Sundays. Some municipalities, like St. Louis and Kansas City, have local laws prohibiting the retail sale of liquor between 1:30 a.m. and 6:30 a.m. Tuesday through Saturday and between midnight on Sunday and 9:00 a.m. the following morning.
Missouri has no specific state limitations on the locations where alcohol can be sold "off-premises."

Missouri also allows the interstate shipping of alcohol into the state, except for wine, as long as the quantity is less than five gallons, it is lawfully manufactured, and shipped to someone over 21 years old. There are no quantity limits for shipments within Missouri or from licensed Missouri alcohol retailers.

Open containers
Missouri does not have a statewide open container law, meaning that it is legal for non-driving passengers, who are 21 or older, to have an open container and drink while in the car. However, this is not universally accepted in every municipality, as some cities and towns have ordinances that prohibit open containers in vehicles. It is the responsibility of both the driver and the passenger to be aware of local open container laws. While it may be legal to have an open container of alcohol in your vehicle, it is never legal to drink and drive or drive while intoxicated. Both actions can lead to criminal and civil punishment.
In Missouri, drunk driving is against the law and is heavily enforced. When a drunk driver gets into a DUI car accident, the state usually imposes harsh penalties, including stripping them of their licenses and possibly jail time. When the laws can change from one milepost to another, it is not a good idea to drive with open alcohol in your car. If you want to ensure you don’t get fined or arrested, it is best to use caution and avoid drinking in public. It is best to only drink on private property.
Missouri also has no statewide law to prevent residents from drinking alcohol in public places. However, some public spaces, such as Loose Park in Kansas City, prohibit alcoholic beverages on public property. Other laws prevent public drinking, such as not allowing places that sell beer to let their customers leave with an open container. In contrast, the Power & Light District in Kansas City allows public consumption of alcohol on its entertainment district grounds, as long as the alcohol is in a plastic container. Additionally, picnickers in public parks in Kansas City can consume alcohol without limitation.
While there is no statewide open container law in Missouri, there are many cities and towns across the state that prohibit the act through local ordinances, so it is important not to assume that it is legal in your location. For example, St. Louis has stricter rules than other areas in Missouri, with local ordinances typically prohibiting both drivers and passengers from having bottles of alcohol in their vehicles. If caught in this situation in the city, even as a passenger, you could face fines or other penalties based on local regulations. Therefore, it is crucial to be aware of the specific regulations that apply in your city or county before transporting open containers.
