Under Naperville curfew laws, anyone under 17 must be out of public places between 11:00 p.m. and 6:00 a.m. on Sunday through Thursday nights, and between midnight and 6:00 a.m. on Friday and Saturday nights. Both the minor and a parent can be cited for a violation, and the city separately enforces a daytime truancy rule during school hours.1Municode Library.

The Hours and Who Is Covered
The nighttime curfew covers every minor under 17. On Sunday through Thursday, they must be off public streets, sidewalks, parks, and other unsupervised public areas from 11:00 p.m. until 6:00 a.m. On Friday and Saturday, the restricted window is midnight to 6:00 a.m. Once a minor turns 17, the nighttime curfew no longer applies.
When a Minor Can Legally Be Out Past Curfew
The ordinance recognizes specific reasons a minor may lawfully be in a public place during restricted hours:
- Accompanied by a parent, legal guardian, or another adult the parent has authorized.
- Traveling directly to or from lawful employment.
- Attending or returning from an event sponsored by a school, religious organization, or government entity.
- Responding to an emergency involving an immediate threat of injury or property damage.
The minor’s presence in public has to connect to one of these reasons. Being outside with no particular purpose or destination does not qualify.
Emancipated Minors
Illinois law gives a defense to minors who are married, were previously married, or have been legally emancipated under the Emancipation of Minors Act.2Illinois General Assembly. Public Act 093-1092 For curfew purposes, they are treated as adults and the restrictions do not apply.
Parents Can Be Cited Too
Naperville does not treat a curfew violation as only the minor’s problem. A parent or legal guardian who knowingly allows a child under 17 to be out during restricted hours faces their own liability. Knowingly does not mean the parent had to send the child out the door. If the parent is aware of where the child is, or fails to exercise reasonable oversight to prevent the violation, that can support a citation against the adult.1Municode Library. Naperville Code of Ordinances Title 10 – Public Order
This is where most families run into trouble. A teenager who sneaks out at 1:00 a.m. can still generate a citation for the parent if an officer concludes the parent should have known or could have prevented it. The standard is not perfection, but the city does expect a reasonable level of supervision.
The Daytime Truancy Rule
Separate from the nighttime curfew, Chapter 3A of Naperville’s municipal code makes it unlawful for a student in grades one through twelve at any public, private, or parochial school within city limits to be absent during the school day without a valid excuse.3Municode Library. Naperville Code of Ordinances Title 10 Chapter 3A – Truancy A parent who knowingly or negligently permits a child under 18 to be truant can be cited. Submitting a false written excuse to school authorities is a separate violation under the same chapter.
Penalties
An officer who encounters a minor apparently in violation of the nighttime curfew can detain the minor until a parent or guardian arrives and can issue a citation to the minor, the parent, or both. Specific fine amounts for the nighttime curfew fall under the city’s general penalty provisions.
For the daytime truancy violation, the code spells out the numbers. A first parental offense carries a fine of $100 to $200 plus court costs; each subsequent offense carries $200 to $500 plus costs.3Municode Library. Naperville Code of Ordinances Title 10 Chapter 3A – Truancy Each day of truancy is a separate offense, so a chronic absence problem can generate significant fines quickly.
A municipal curfew citation is not a criminal charge. Curfew violations in Illinois are handled as local ordinance matters rather than criminal or juvenile delinquency cases, so they generally do not produce a criminal record the way a theft or assault charge would. Repeated citations still create a documented municipal history and can draw closer attention from law enforcement or school officials.
If Your Child Gets a Citation
You will likely need to appear before Naperville’s administrative hearing process or the local court, depending on how the ticket is routed. Ignoring the citation does not make it go away and can lead to additional fines or a failure-to-appear notice.
The strongest defense is showing that one of the recognized exceptions applied. Gather documentation before the hearing: a work schedule if the minor was heading home from a job, a flyer or program if it was a school or religious event, anything that ties the minor’s presence in public to a permitted reason. If the citation also names you as the parent, be ready to describe the supervision you had in place, even if your teenager was out past curfew despite it.
