ZTL: Italy's limited traffic zones

How the system works, and how the fine reaches you

The mechanism is identical in the 5 cities documented below: cameras at the entry gates read every plate, authorization is tied to a plate and to a time band, and nothing stops you at the boundary. The penalty notice is issued afterwards, by post.

With a rental car the sequence has an extra step. The rental company receives the request for driver details, charges you an administrative fee for handling it, and that charge often lands on your card before the fine itself arrives from the municipality.

Those 5 cities are Rome, Florence, Milan, Naples and Bologna. Bologna is on the list on the strength of search results only, because the city's own pages are built client side and could not be read.

Rome: five zones, and a Saturday that changes

Rome has 5 limited traffic zones, and the widest is the Tridente around via del Corso, which on Saturday stays on until 7:00 pm.

Public holidays are excluded from the Centro Storico. Night zones are suspended in August.

The system is controlled by 50 electronic gates, a figure taken from a descriptive page and never reconfirmed. Hours also change by temporary ordinance for events, so verify before you rely on them.

Florence: the whole center, in five sectors

The entire historic center of Florence is a ZTL, divided into 5 sectors: A, B, O, F and G. In A, B and O it operates all year on working days, 7:30 am to 8:00 pm Monday to Friday and 7:30 am to 4:00 pm on Saturday.

A summer night ZTL is added from the first Thursday of April to the first Sunday of October, on Thursday, Friday and Saturday nights, indicatively 11:00 pm to 3:00 am, with exact dates fixed each year by ordinance. Some gates are closed 24 hours a day to everything except public transport and emergency vehicles.

Milan: two different schemes with similar names

Area C is the paid ZTL of the city center, covering the Cerchia dei Bastioni: 7.50 euro a day for most vehicles, active Monday to Friday 7:30 am to 7:30 pm, holidays excluded.

Rates have applied since October 30, 2023.

Area B is a different animal: a low emission zone, far larger, with no ticket at all. It bans the most polluting vehicle classes on a rolling calendar, and the city says it acts on 65% of annual traffic emissions. Its exact perimeter and hours are not published on a page we could read, and the regional MoVe-In telematic box is the alternative for vehicles that would otherwise be banned.

Naples: four gates in the old center

The Centro Antico of Naples is a ZTL with 4 electronic gates, and only the via del Sole one runs longer at the weekend.

Access is for residents, businesses inside the zone, deliveries, doctors on home visits, authorized public service vehicles and patients heading to clinics inside the area. Temporary permits are requested by email from the city. Naples has other ZTLs beyond the Centro Antico, at Mezzocannone, via Ferdinando Russo and Chiaia, which are not covered by the source above.

The cities we cannot map yet

4 cities are documented here with hours from official pages: Rome, Florence, Milan and Naples. Bologna, Verona, Pisa, Siena, Lucca, Turin, Palermo and dozens of smaller towns also operate ZTLs, and we have no verified perimeter or timetable for them.

Treat any Italian historic center as restricted until you have checked. The safe move is to park outside the walls and walk in, which in most of these towns takes less time than finding a legal space inside.
