Final answer:
The curfew for minors at the age of 18 varies by jurisdiction, and there is no nationwide curfew specifically for 18-year-olds.
Step-by-step explanation:
In the United States, the curfew for minors at the age of 18 varies by jurisdiction. There is no nationwide curfew specifically for 18-year-olds, as the legal age of majority for most purposes is 18. However, some cities or states may have curfew laws that apply to individuals under the age of 18, regardless of whether they are still considered a minor. For example, in New York City, individuals under the age of 18 must be off the streets and in their homes by 11:00 PM on weeknights and by midnight on weekends.
