53. Low-emission zone

A low-emission zone, or LEZ, is a defined area where access by more polluting vehicles is restricted in order to reduce traffic-related air pollution. Vehicles that do not satisfy the required emission criteria may be prohibited from entering or may require a temporary permit, exemption or day pass.

Access rules commonly depend on factors such as the vehicle category, fuel type and Euro emission standard. Low-emission-zone requirements vary between countries and cities, so drivers should check the applicable rules before entering the zone.

How are low-emission access restrictions applied in France?

French zones à faibles émissions mobilité (ZFE-m) can limit access by vehicle class and pollution category. A suitable Crit’Air certificate is normally required within an operating ZFE-m; check that city’s current rules.

Does a French Crit’Air certificate guarantee access to every ZFE-m?

No. Crit’Air identifies the emission classification, but a city’s active ban, hours and exemptions determine whether that particular vehicle may enter.

Does entering an emissions-restricted area change the speed limit in France?

No, not solely because of its emissions designation. Obey the separately applicable speed signs, vehicle restrictions and priority rules. A permit or emissions exemption does not override the normal traffic rules.
