Premises

• Hotels and hostels may require guests to return to their rooms before a certain time, after which they will lock the front door. According to the Hostels website, many hostels no longer enforce curfews. Many bars are legally required to impose curfews according to an area's licensing laws. Others may need to enforce curfews following instances of disruptive behavior. In 2010, police in New Orleans enforced a curfew that operated between midnight and 6 a.m. on the bars and clubs on Bourbon Street and other French Quarter thoroughfares.
  
  

Minors

• Minors in a number of American cities are subject to curfews, which the local authorities claim helps prevent disruptive behavior. According to the National Youth Rights Association, however, there has never been any serious empirical study on the efficacy of curfew laws. In the Phoenix metropolitan area, the curfew is 10 p.m. to 5 a.m. for any aged under 15 and midnight to 5 a.m. for children aged 16 or 17, at the time of publication. Those caught breaking curfew will be arrested. According to the ABC news station 15, Phoenix police Lt. Jacquelyn MacConnell claims that there is a definitive link between underage kids out at night and crimes activity.
  
  

Civil Unrest

• Governments may impose curfews in times of civil unrest. According to the National Youth Rights Association, Justice Douglas of the Supreme Court stated that curfew laws may be necessary when the security of the country is threatened, but that they raised serious questions regarding the rights of citizens to freely assemble. He suggested that any curfew laws should be narrowly defined and temporary.
  
  

Sentencing

• Judicial curfews are sometimes imposed on criminals on probation. In the U.S., a condition of a person's bail may be to meet a police officer at the door of the agreed premises within the period of curfew, which is referred to as a doorstep condition, according to the Law Library. Curfews may also be imposed on defendants as a condition of pre-trial release. Both defendants and probationers may incur the cost of monitoring their compliance with the curfew.
