Juvenile curfews are legal restrictions that prohibit youth under a certain age (usually 16, 17, or 18) from being in public places without adult supervision during certain hours, usually at night (e.g., between 11 p.m. and 5 a.m.). Curfew restrictions regarding youth ages, hours, exempted activities, and penalties for violations vary by locality. Many states allow local governments to enact curfew laws or ordinances.

What does the research say about effectiveness?

There is strong evidence that juvenile curfews do not affect youth crime and victimization rates during curfew hours1, 2. A Washington, D.C.-based evaluation indicated that changing curfew hours from midnight to 11 pm increased gunfire incidents between 11 pm and midnight3.

Available evidence suggests juvenile curfews may reduce youth motor vehicle fatalities and arrest rates; additional research is needed to determine effects on fatalities and arrests4.

How could this strategy impact health disparities? This strategy is rated no impact on disparities likely.
Implementation Examples

Hawaii is the only state with a statewide juvenile curfew. Hawaii’s curfew restricts children under the age of 16 from being in public places between 10 p.m. and 4 a.m.5.
