Traditional teen curfews require teenagers to be home by a specific time. A “leave by” curfew takes a different approach: teens must leave their friend’s house, party or other destination by an agreed-upon time, giving them room to travel home safely without rushing.
The idea gained attention after mother Johanna Trask shared her family’s approach online. The strategy aims to reduce pressure on teens to speed home to meet a strict arrival deadline.
The approach can encourage teens to plan their journeys and communicate with parents about their whereabouts. However, it still requires clear expectations about transportation, check-ins and what happens if plans change.
Are Teen Curfews Effective?
Curfews can give families structure and help teenagers balance social activities with sleep, school and other responsibilities. However, evidence that curfews prevent crime is less convincing, particularly when looking at laws that restrict young people from being in public at certain hours.
The Marshall Project conducted a review of 12 rigorous studies and found that juvenile curfew laws were generally ineffective at reducing crime and victimization. The article also highlighted concerns about disproportionate enforcement and strained relationships between young people and police.
These findings concern public curfew laws, not necessarily agreements families make with their own teenagers. A household curfew may still help establish routines, encourage accountability and give parents peace of mind, although its success depends on how it is used.
How Should Parents Set a Curfew for Teens?
Parents should consider their teen’s age, maturity, activities, transportation options and need for sleep before setting a deadline. In guidance from WebMD, parent Mary Francine explains that her family adjusted curfew times as her children grew older.
Discuss expectations together and agree on when teens should leave, how they will get home and when they must contact you if plans change. Make sure everyone understands local curfew laws, too, since a family agreement does not override legal requirements.
Keep consequences proportionate, and recognize responsible behaviour with greater flexibility over time. Whether you choose a traditional curfew or a “leave by” rule, the goal is to build trust, safety and independence—not simply to enforce a clock.
