Question: can a passenger drink alcohol in a car in missouri

Answer: Yes, Although a driver is prohibited from consuming alcohol while driving, Missouri has no general open container law for vehicles, a characteristic which Missouri shares only with the states of Arkansas, Connecticut, Delaware, Mississippi, Virginia, and West Virginia. Any non-driving vehicle passenger thus is permitted to possess an open container and consume alcohol in Missouri while the vehicle is in motion, although 31 smaller municipalities, the largest being Independence and St. Charles, have local open container laws. The metropolises of St. Louis and Kansas City have no local open container laws, and thus the state law (or lack thereof) governs. This makes it possible for a passenger to drink legally through the entire 250-mile (400 km) trip across Missouri on Interstate 70 between Downtown Kansas City and Downtown St. Louis, only closing the container while passing through the city limits of Independence, Bates City, Columbia, Foristell, and St. Charles.
