We don't have named driver policies in Italy. I suspect most people only have the compulsory insurance which covers damage or injuries caused by the driver but not your own car. For someone with no claims history that costs about 450 to 500 euro a year. Fully comprehensive insurance can cost around 1,800 or more a year depending on the car and the value insured.
I have no idea why Italy is so expensive for insurance, i would have thought that the number of fraudulent claims would not be all that different to other countries, and I don't see driving more dangerous here than elsewhere.
not sureif it is the same in Italy but here in the uk a major factor is third party injury claims. It doesnt take too many £5 million paraplegic claims to affect the average claims
