Exemptions from the rules for environmental zones in France

Some vehicles are exonerated from the obligation to enter the environmental zone only with a Crit'Air Vignette. Especially vehicles of public services (police, fire brigade, emergency service, etc.) and other vehicles of public enterprises.
As per French decree Décret n°2016-847 from 28th June 2016 vehicles bearing a parking card for disabled persons need no Crit'Air Vignette. Parking cards for disabled persons are the same all over Europe so that vehicles of handicapped persons are recognisable abroad, too.
Other private vehicles can also be liberated from the obligation to bear a Crit'Air Vignette. But this happens only by means of a special approval from the state or the community.
Here are particular opportunities for vintage cars, old tourist vehicles, breakdown services, etc.
