About ZTL Map

ZTL Map is an independent project by Josep Mampel Marques, a software engineer based in Spain. It is a free guide to Italy's limited traffic zones (ZTL) for drivers, especially visitors with a rental car: a map of the zones and a checker that tells you whether a point is inside one and whether it is active now in Italian time.

Why it exists

The official ZTL maps are mostly PDF files or images, in Italian and without a date, and the hours are spread across ordinances, notices and press articles. Visitors ask the same questions every day: is my hotel inside the ZTL, is it active now, and what happens if I drove in? ZTL Map tries to answer them in one place, with a source for every answer.

Where the data comes from

Zone boundaries come from the cities' own open data where it exists (Florence and Milan, CC BY 4.0) and from OpenStreetMap elsewhere (Rome, Bologna and Lucca, © OpenStreetMap contributors, ODbL). The hours are our own table, with a source and a check date for each zone. When sources disagree we use the more restrictive hours, and when we cannot verify the hours we say so. The method page explains everything.

How we write the guides

The guides are based on published sources, listed at the end of each one: city open data, ordinances and regulations, the Italian Highway Code, European consumer centres and the Italian motoring press. Where a fact comes only from a secondary source, we say so. We do not publish stories or experiences we have not had, and we give general information, not legal advice.

Not affiliated

ZTL Map is not affiliated with any Comune, police force, rental company or the Italian government. Always check the official source, and follow the sign at the entrance to a ZTL: it is the rule that counts.

Corrections

If a sign, an hour or a boundary does not match what we show, please tell us on the contact page. We fix errors and update the check date on the page.
