The most polluting vehicles are banned from circulating within Rome's fascia verde (green belt) inside the Raccordo Anulare ring road on Friday 2 March, from 07.30 until 20.30.

The measure affects Euro 0 and 1 petrol-driven cars, Euro 0, 1 and 2 diesel vehicles, two-, three- and four-wheel 2 and 4-stroke mopeds and motorbikes and Euro 0 and 1 diesel minicars.

The ban is in response to high pollution levels which in recent days have exceeded the statutory limit for smog particulate matter (PM10) and nitrogen dioxide (NO2).
