Final answer:
The claim that drivers must be 14 to operate a moped is false, as moped age requirements vary by state and are commonly older than 14. MADD's role in the drinking age legislation reflects their impact on laws relating to youth safety, but the driving age for mopeds is determined by individual states.
Step-by-step explanation:
The statement 'Drivers must be at least 14 years of age to operate a moped' is generally false. The specific age requirement to legally operate a moped varies by state, but in many places, the age is older than 14. For instance, some states require a minimum age of 15 or 16. It's important for potential drivers to check their state's specific requirements.
Regarding MADD's influence and the minimum drinking age, there is indeed a variation in the enforcement of alcohol-related laws across different states due to the rights reserved by the Twenty-First Amendment for states to regulate alcohol. MADD's lobbying for the National Minimum Drinking Age Act of 1984 illustrates such efforts to regulate and protect youths. However, this pertains to alcohol regulation and not directly to age requirements for operating mopeds, although it reflects the role of organizations in shaping laws that affect young drivers and their safety.
