Hours and gates
How Rome's ZTL works
Rome's ZTL isn't a single zone, but a set of areas with different hours, watched over by electronic gates with cameras. The most relevant for those staying in the centre are the ZTL Centro Storico and the ZTL Tridente — the latter the strictest, in the pedestrian heart between Piazza di Spagna and the Corso.
Broadly speaking, the ZTL Centro Storico is active Monday to Friday from 6:30 to 18:00 and on Saturday from 14:00 to 18:00, with a night band on Friday and Saturday from 23:00 to 3:00. The ZTL Tridente is active Monday to Friday from 6:30 to 19:00 and on Saturday from 10:00 to 19:00. On public holidays, as a rule, access is free, and in August the ZTL is usually suspended.
Be careful, though: hours and boundaries change, are suspended in certain periods and have been revised recently. Don't trust your memory or old maps: always check the up-to-date information on the Roma Servizi per la Mobilità website in the days around your arrival. It's the only source that counts.
