The next traffic free day in Rome will be on Sunday 26 September. The "ZTL" the zones of the city where traffic is limited, which includes the historic centre, Trastevere and S. Lorenzo, will be closed to all private cars and motorcycles (including residents vehicles) from 10.00 -18.00. Traffic free days are held to encourage the Romans to enjoy the city on foot and bicycle and to lower levels of pollution. This particular ban comes at the end of European Mobility week when people Europe-wide are being asked to help reduce pollution caused by motor vehicles, cut over-consumption of energy and, this year's hot topic, reduce road safety risks for children in cities. The day chosen as European mobility day is Wednesday 22 September but the Roman authorities have shifted it to the following Sunday.

The final car free Sunday of the year will be on 7 November.
