Bologna ZTL: Sirio hours and the T zone
The Bologna ZTL is active every day, Sunday included. The central ZTL is preset: pick the time to see whether Sirio is on.
Independent site, not a city service: the municipal order and the signs at the gate are what count.

Zone hours
- every day 7:00–20:00
Also active on public holidays, according to the source.
Bologna’s limited-traffic zone is a wide area of the historic centre where motor traffic is restricted. According to the description of the dataset published in the City of Bologna open data, entries are controlled by the Sirio camera system, the “electronic warden”, every day from 7:00 to 20:00: on Saturday, Sunday and public holidays too, because the source says “every day” with no exceptions. Inside the ZTL some zones are closed 24 hours a day: the pedestrian zones and the T zone. Since 1 January 2020 the environmental ZTL has been in force, changing the criteria for access to the historic centre and the parking rules. The perimeter dataset counts 14 areas under order 4000/343434, but its description dates from 26 August 2021: it is the most recent open official source we found with the hours written out, and that is why we always show its date. Outside the 7–20 period any vehicle may enter, except in the T zone and the pedestrian areas.

Sirio, the electronic warden
Sirio is the name of the camera system that reads plates at Bologna’s ZTL gates. It works like other camera gates: it compares the plate with the list of authorised vehicles and, if it does not find it during the active period, the municipal police draw up a fine. Repeated entries on the same day in the same ZTL count as a single fine, under article 198 of the Highway Code.
A source to confirm at the gate
The hours come from the description of the official dataset, which the city publishes under CC BY 4.0 but which has not been updated since 2021. The city website’s ZTL pages cannot be read without JavaScript and we could not compare them. Before entering, look at the sign at the gate; if you see different hours, write to us. For holidays, the public holidays page shows which cities stay closed even at Christmas.
