The document discusses arguments for lowering the legal drinking age in the United States from 21 to 18. It notes that highway fatalities related to alcohol were decreasing before 1984 when the National Drinking Age Act was passed. Other factors like education, designated drivers, safety features in cars, and lower speed limits contributed to the decline in traffic deaths. The document argues that an 18 year old is considered mature enough to take on other responsibilities like military service, voting, and jury duty, so they should be able to legally drink alcohol. It concludes that lowering the drinking age could help reduce unsafe binge drinking if 18 year olds are taught responsible drinking habits.
