The anello ferrovario extends to Piramide near Ostiense in the south, the Valle Aurelia stop on the metro A line in the west, just beyond Stazione Campi Sportivi in the north and Stazione Tiburtina in the east.

The 1 November ban applies to residents inside the anello ferrovario, who had previously been exempt from the 1 January ban forbidding non-residents to enter the area on Euro 0 bikes.

Most scooters and motorcycles manufactured before 1999 fall into the Euro 0 category. Transgressors will be fined €71, rising to €141 if the driver does not have a bollino blu vehicle pollution health-check certificate. Registered classic motorbikes are exempt from the ban.
