Understanding Crit'air

Article updated on 11/16/2021

Crit'air facilitates the identification of the least polluting vehicles through a colored vignette affixed to the vehicle and entitled certificate of air quality (Crit'Air). It allows the least polluting vehicles to be able to travel in agglomerations where traffic restrictions have been put in place to reduce pollution.

To know the categorization of your vehicle as well as the restricted circulation zones concerned, go to the official website of the French administration.
