Section 2 of 4
The camera at the gate
How a ZTL works, and when the letter arrives. A limited-traffic zone has no barrier and usually nobody to ask. The sign at the mouth of the street is the whole of the notice, and the enforcement arrives later, by post.

Four guides in this section
- The camera at the gateAlmost every Italian historic centre is a limited-traffic zone enforced by camera, and the boundary is a line on a pole rather than a barrier.
- How a varco works, from the pole to the postThe gate reads the plate, the plate is checked against a permit list, and what arrives months later is a notice by post.
- When the letter arrivesNotices reach a foreign registered keeper through the hire company or the vehicle register, which is why they are so delayed.
- Nobody stops you at the gateThere is no barrier and no official — the enforcement is entirely after the fact, which is what catches people out.
