ZTL camera gates: how they work and when on
A ZTL camera gate photographs every plate but only fines while the zone is active. Rome’s Tridente is preset: pick a city, zone and time.
Independent site, not a city service: the municipal order and the signs at the gate are what count.

A ZTL gate (varco) is a camera checkpoint at the entrance to, or inside, a limited-traffic zone. The City of Turin describes how it works clearly: the plate of every vehicle entering is photographed and compared with the authorised ones, which are added to a database when a permit is issued. If the plate is not there and the zone is active, the offence is recorded. Turin has 41 checkpoints: 27 at the entrances of the ZTL Centrale, 11 inside it for the areas with stricter limits and 3 for the Statuto, Valperga and Valentino areas. In Bologna the system is called Sirio; in Milan, Area C and Area B are controlled by electronic gates, and Area B is marked out by blue gates. A new gate does not issue fines straight away: for Valentino the city notice states that controls start only after approval by the Ministry of Infrastructure and Transport and include a trial period. Finally, since 14 December 2024 several entries into the same ZTL on the same day count as a single fine.

One fine per day, not per gate
Article 198, paragraph 2-bis, of the Highway Code says that when entries into the same ZTL are recorded by cameras, a single fine applies for each calendar day. A driver who circles the centre and passes four gates of the same zone in a morning gets one notice. The rule speaks of the same ZTL: entries into different zones, for example Rome’s Historic Centre and Trastevere, are not covered by it.
