Final answer:
The statement is false; licensees cannot sell or deliver alcohol to a second-party purchaser under the age of 21, in accordance with the National Minimum Drinking Age Act of 1984 and the regulations set by individual states.
Step-by-step explanation:
The question addresses whether licensees may sell or deliver alcohol to a second-party purchaser as long as they're over the age of 19. The legal drinking age in the United States is set at 21 years old as per the National Minimum Drinking Age Act of 1984. This act required states to raise their drinking age to twenty-one or else they would face a 10 percent reduction in federal highway funds. This legislation was heavily influenced by organizations like Mothers Against Driving (MADD), who lobbied for stricter laws to prevent the dangers associated with underage drinking, such as intoxicated driving.
Considering the national law, the statement in the question is false. Licensees are generally not allowed to sell or deliver alcohol to anyone under the age of 21. Furthermore, there are specific regulations regarding who can act as a second-party purchaser, and these regulations also vary state by state. It is important for licensees to understand and comply with both federal and state laws regarding alcohol sales to avoid legal penalties.
