curfew

A curfew is a regulation that requires people to stay off the streets or indoors after a certain hour. Historically, curfews originated from the need to extinguish fires in medieval timber-built cities, with a bell signaling inhabitants to "cover fire".12

In modern criminal justice, curfews are a form of house arrest, restricting an offender's movement to their home during specified times, often evenings. This can range from requiring someone to be home by a particular time to stricter home confinement or home incarceration, sometimes enforced by electronic surveillance. Curfews are used at various stages of the criminal justice process, including pretrial confinement, as a sentencing alternative to incarceration, and for early release and community reintegration. They aim to ensure public safety, reduce jail overcrowding, and provide a less punitive, more cost-effective alternative to traditional imprisonment.3
