In Brief
Italy is set to tighten the enforcement of ZTLs (Restricted Traffic Zones) starting October 1, 2026, primarily affecting cities with populations over 100,000 people such as Milan, Bologna, and Venice. This hardening aims to curb the circulation of polluting vehicles, notably Euro 5 diesel cars, in line with European Union directives designed to curb urban pollution. Roughly 10 million vehicles are expected to fall under these new rules. Each Italian city will implement its own modalities and restrictions, impacting both residents and visitors. In France, Paris hosts ZTLs, while ZFE (Low Emission Zones) exist with an uncertain future.
The crackdown on polluting cars continues across Europe. Millions of drivers will be affected by this well‑known restriction, with its rollout taking effect on October 1, 2026.
A tightening that also affects tourists
Traffic restrictions aren’t limited to French motorists. In many European countries, measures are being put in place to the dominance of the most polluting vehicles and thus cut emissions in major cities. This is true in France as well as in Italy. Our Italian neighbors introduced, a while back, the ZTL — Zones with Limited Traffic. While the concept isn’t new, the big change lies in the tightening of current rules. This update arrives in October 2026.
It will affect cities with more than 100,000 residents, such as Milan, Bologna, and Venice. Initially, Italy planned to apply this measure to cities with more than 30,000 residents before raising the threshold. Regarding the details of the scheme, each city can establish its own system, including hours or days when access is banned. Being well informed is therefore essential, especially since tourists will also be subject to the ZTL regime.
In France, the ZFE remains in political‑legal limbo
This tightening of rules is not a trivial decision, as it directly responds to European Union directives. The EU aims to minimize atmospheric pollution and to combat fine particulates in urban areas. Consequently, Italy is tightening the ZTL. The measure is expected to affect nearly 10 million vehicles. Diesel cars, among the models classified as Euro 5, will now be subject to these circulation restrictions.
For reference, a ZTL is a zone where driving is prohibited unless you stop inside it — either because you are a resident or because you have an appointment or groceries. Crossing the zone is forbidden on certain days and times. In France, the ZTL is in place in Paris and focuses on the city’s hypercenter, specifically the districts 1 through 4.
France has also implemented ZFE (Low Emission Zones). While much opposition exists to this policy, the state continues to pursue its implementation. To date, ZFE zones remain in effect in the Hexagon.
