In the event of further deterioration in air quality, new, more restrictive measures may be taken, in particular the introduction of differentiated traffic. The differentiation between vehicles authorized or prohibited to circulate is based on air quality certificates called Crit’Air vignettes. In concrete terms, during the first two days of the pollution episode, only vehicles with a Crit’Air sticker will be authorized to circulate within a defined perimeter. From the 3rd day, vehicles without vignette and class 4 and 5 will no longer be able to circulate.
The scope will be defined for each episode depending on the situation.
Air quality is a major public health issue and the Prefect appeals to everyone’s civic conscience to limit pollutant emissions throughout the year.
