If you're a non-EU citizen that would like to rent a car in Italy, it's essential to hold an International Driver's Permit. The Italian car rental might not ask for it, but it is required by law that you have one, and it may be requested during a police check.
When renting a car in Italy you must purchase collision (CDW) and theft insurance. Declining this insurance is not an option and the price you are quoted will always include it. Sounds good except there's a catch: the insurance comes with a substantial deductible or excess, usually in the €1000 to €3000 range.
Debit card car rentals are available at Hertz locations in Belgium, Czech Republic, France, Germany, Italy, Luxembourg, The Netherlands, Slovakia, mainland Spain and the UK.
When you are on the motorways, you will need to look out for signs marked 'Alt Stazione' – this is where you make the payment at the toll booth. All payments are made in Euros at either a manned or electronic booth – however, they do accept debit cards from other countries.
