According to the latest estimates of Ania (Association of Insurance Companies) and Aci (Italian Automobile Club), in Italy there are between 3 and the 4 million cars that circulate without the policy Rc Cars.
From north to south, the phenomenon has become a real social problem. Waiting for it to arrive at the definition of the introduction of computerized checks on insurance coverage, car, motorbikes, and vans (see decree of the Government Monti "Grow Italy", that as in many other cases remains incomplete subsequent decrees, standards, implementing provisions, etc.), let's see what to do in case of an accident with an uninsured vehicle.
The institution in charge to intervene in these cases is the Guarantee Fund for the victims of the road (http://www.consap.it/fondi-e-attivita/mondo-assicurativo/fondo-di-garanzia-per-le-vittime-della-strada), established in 1969, the same year in which the insurance has become compulsory TPL.

Every time a motorist pays their insurance RC Cars, a share of the amount to be paid into the Fund.
The rate, now equal to 2,5%, looks set to grow in the future given the rise not only of uninsured vehicles but also the increasing number of incidents of road rage, since for these acts the same Fund.
Depending on the area where you are resident, the Ivass (Supervisory insurance undertakings) Company designates a delegate to receive the accident report, to be sent by registered mail with return receipt, which lists all the possible information to identify the vehicle that caused the accident (brand, type, plate, testimonies, any record of the police, medical records in the event of physical damage).
And 'then essential to send a copy to Consap (www.consap.it - Via Yser, 14 00198 Rome). On this site you can find more information and see a list of Companies delegated on your area.
