Curfew Pass

A Curfew Pass or Movement and Curfew Pass is a document issued by an empowered authority such as police or military for public officials or civilians to travel within or to and from an area under an imposed curfew by the said authority.

Trivia
The A 38 pass from the animated film Asterix Conquers Rome, a satire on bureaucracy, is now used to describe it.

In March 2020, there was a partial curfew in France due to the COVID-19 pandemic, and it was compulsory to carry a self-completed Attestation de déplacement dérogatoire form with you in public, stating a valid reason (including work, shopping or sport) for leaving the house. This certificate was also referred to as a "pass" in the German-speaking media.
