One Crit'Air vignette for each registration number!

The Crit'Air badge not only corresponds to the Euro standard of a vehicle, but also to the registration number. In concrete terms, the owners of the vehicle must order a new badge if the registration number changes. At least the thief in Billy-Montigny (Northern France) who was caught because of an old Crit'Air vignette will have learned that! Watch out then!
