Alcoa Municipal Code Section 11-708 Curfew for Minors describes the ordinance for minors.
“It is unlawful for any person who has not reached his/her eighteenth (18th) birthday to loiter, wander, stroll, or play in or upon the public streets, sidewalks, highways, roads, alleys, parks, playgrounds or other public grounds, public places, public buildings, places of amusement, eating places, vacant lots or any place unsupervised by an adult having the lawful authority to be at such places between the hours of 10:30 p.m. and 6:00 a.m. Sunday through Friday and between the hours of 11:30 p.m. and 6:00 a.m. Friday through Sunday”; with some exceptions.
The exceptions include when the person is accompanied by an adult; on an authorized errand or out during curfew hours while employed. However, remember, if a police officer observes a person who appears to be under the age of eighteen years of age, he or she has the authority to detain that person to determine if they are in violation of the curfew laws.
