A ZTL, or zona a traffico limitato, is a limited traffic zone, usually the historic center of an Italian city, where only authorized vehicles may drive during set hours. Cameras at the entry gates read the plate of every car that passes, so a rental car that enters a ZTL in Italy at the wrong time can bring a fine weeks or months later. This guide explains how the zones work, the hours in Florence, Rome, Milan, Pisa and Bologna, and what happens when the car is a rental.
How do ZTL zones in Italy work?
Each city sets up its own zones. The Italian Highway Code lets municipalities mark out limited traffic zones, and it allows them to make entry into a ZTL subject to a payment. Driving in a ZTL without authorization is fined 83 to 332 euros, the same range as driving in a bus lane or a pedestrian area.[1]
Because each city decides, the hours, the days and who may enter change from one city to the next, and sometimes from one zone to the next within a city. In Rome, for example, access to the five ZTLs is reserved for authorized vehicles with a permit, on certain days and at certain hours.[2] Outside those days and hours, the restriction does not apply.
Two points follow for a visitor in a rental car. First, the sign at the gate is not enough: you need the hours of that zone on that day. Second, the gates read plates, so for a rental car an authorization usually means that someone, such as a hotel in the zone, registers its plate with the city, as hotels can in Bologna and Pisa, or that you buy a ticket where the city sells one.
What are the ZTL hours in Rome?
Rome has five ZTLs: the Centro Storico, the Tridente, Trastevere, San Lorenzo and Testaccio. The Centro Storico has a daytime zone and a night zone, Trastevere has both, and San Lorenzo and Testaccio close only at night.
| Zone | Closed to unauthorized vehicles |
|---|---|
| Centro Storico, day | 6:30 to 18:00 Monday to Friday; 14:00 to 18:00 Saturday; not on public holidays |
| Centro Storico, night | 23:00 to 3:00 Friday and Saturday; not on public holidays; not in August |
| Tridente | 6:30 to 19:00 Monday to Friday; 10:00 to 19:00 Saturday; not on public holidays |
| Trastevere, day | 6:30 to 10:00 Monday to Saturday; not on public holidays |
| Trastevere, night | 21:30 to 3:00 Friday and Saturday, holidays included; also Wednesday and Thursday from May to October; not in August |
| San Lorenzo, night | 21:30 to 3:00 Friday and Saturday, holidays included; also Wednesday and Thursday from May to October; not in August |
| Testaccio, night | 23:00 to 3:00 Friday and Saturday; not on public holidays; not in August |
The exemptions cover the categories set by law, among them taxis, NCC cars, and motorcycles and mopeds (except in the Tridente). NCC stands for noleggio con conducente, a car hired with a driver, so a rental car you drive yourself is not covered. If you pick up a car in Rome, the simplest plan is to collect it or return it outside these hours, or at a location outside the center.

What are the Florence ZTL hours?
The whole historic center of Florence is a ZTL. It is bounded by electronic gates with signs, and the equipment on them automatically records the plates of all vehicles that pass. The zone has five sectors: A, B, O, F and G. In sectors A, B and O, the ZTL is active all year on working days, from 7:30 to 20:00 Monday to Friday and from 7:30 to 16:00 on Saturday. Some gates, meant only for public transport and emergency vehicles, are closed 24 hours a day.[3]
In summer, a night ZTL is added. In 2026 it ran from 2 April to 3 October, from 23:00 on Thursday, Friday and Saturday to 3:00 the next morning. It covers sectors A, B and O, plus sectors F and G, which apply only to the summer scheme: the San Niccolò area, and the area of piazza Cavalleggeri, lungarno della Zecca Vecchia and piazza Piave. The city confirms the hours each spring, so check them before a summer trip.[4]
If you collect a car in Florence, ask whether the pickup point is inside the ZTL and which route leaves the center without passing a gate during its hours.
How does Milan’s Area C work?
Area C is a limited traffic zone in central Milan that requires a fee to enter. Entry is regulated by electronic gates that detect license plates, and the zone is active all year, Monday to Friday from 7:30 to 19:30, except on public holidays. A ticket lasts one day, and the city’s site lets you check by plate and nationality whether a vehicle may enter at all, since some vehicle classes are banned.[5]
A ticket does nothing until you activate it. You link the PIN on the ticket to the car’s plate, online or by phone, and online activation does not require registration. The deadline is midnight of the day after you entered the zone, or midnight of the same day for a ticket bought in an affiliated garage. An activation made the day before the entry, or after the deadline, does not cover the entry, and the passage is fined.[6]
The standard ticket costs 7.50 euros for any vehicle. After that deadline, only a deferred ticket covers the entry: it costs 22.50 euros if paid by midnight of the seventh day after the entry.[7] The 22.50 euro ticket, the city says, requires registration on its MyAreaC portal. With a rental car from Milan, you will need the plate to activate a ticket, so note it when you collect the car.
What about the ZTL in Pisa and Bologna?
Pisa has a ZTL too. The city has an online service that lets professional accommodation, meaning hotels, B&Bs and similar, register the plates of guests’ vehicles for access to the ZTL. A hotel has to register for the service, and its requests are subject to approval.[8] If your hotel in Pisa is in the center, ask whether it registers plates before you drive to it, and send the plate once you have the car.
Bologna’s ZTL is a large zone in the historic center. The Sirio system controls access every day from 7:00 to 20:00, and some areas inside the zone, the pedestrian zones and the T zone, are restricted 24 hours a day.[9] Without a permit, a visitor can buy a ticket for 6 euros a day, or 15 euros for four days, and must activate it with the car’s plate before entering the ZTL; it is not valid in the zones closed 24 hours a day or in the bus lanes.[10]
A guest of a hotel or B&B in Bologna’s ZTL can ask the manager for a permit: the hotel passes the plate to the city, which adds it to the list of authorized vehicles to avoid fines at the entrance to the ZTL, which the Sirio cameras control. Give the car’s details to the hotel before you arrive or, failing that, on arrival. Hotel guests can also buy a daily pass from the hotel, for 9 euros, for on-street parking, valid for 24 hours from validation in all the city’s paid blue-line areas. Even with the permit, you can never drive into the zones closed 24 hours a day, among them the pedestrian zones, the bus lanes and the T zone of via Ugo Bassi and via Rizzoli, unless your hotel is inside one of them, in which case it gives you the authorized route.[11] For more on renting in the city, see the Bologna page.
What happens if a rental car enters a ZTL?
The camera records the plate, and a rental car is registered to the rental company. Under the Italian Highway Code, when a car is rented without a driver, the renter, in place of the owner, is jointly liable with the driver for the fine.[12]
When an offense is not contested on the spot, as with a camera at a ZTL gate, the authority has 90 days from the date the offense is recorded to serve the notice on the person responsible, and 360 days when that person lives abroad. If the person is identified later, the 90 days run from the date the authority is able to identify them.[13] The rental company may charge a fee for passing on your details, so check your contract.
The fine for the entry itself falls within the 83 to 332 euro range of the Highway Code, and in a paid zone such as Area C the unpaid charge is added to it. In Milan’s Area C, an entry without a ticket activated in time, or a deferred ticket paid in time, is fined as well, even though the zone is open to cars that pay.
