Fine circulation in Turin

Many tourists and visitors, including Italians, major cities of the peninsula have more often than not the very unpleasant surprise to receive tickets several months after their visit.

ZTL Turin A very unpleasant feeling seized more and more tourists, including the Hautes Alpes, going to Turin. Several months after their visit, sometimes until almost a year later. Motorists are fined for "access in pedestrian zone or restricted traffic area without the necessary authorization". Hundreds of messages dot social networks and internet forums about it.
These areas of downtown, in Turin but also in Rome, Milan, Florence, Pisa, Bologna or Naples seem reserved for the owners of a vehicle registered in the city.

Are there differentiated access rights according to the pollution level of the vehicle attested by the Crit'air or other vignettes?
The beautiful city of Turin, but also the other Italian cities concerned, it would not gain better information to users of the road to avoid this kind of inconvenience: larger and better arranged panels, retractable terminal system, luminous indications , information on tourist offices sites etc ...?
