Car Rental at Roma Airport (RMA) from $57

If you don't have a driver's license issued in Australia, then you may need to acquire an International Driving Permit (IDP) in your home country to be able to rent a car. It's also important to note that if you do need an IDP, it won't be valid on its own. You'll have to show your driver's license from your home country your passport and other forms of identification as well. Lastly, it's important that the credit card you used to book the rental matches the name on your license and passport. Some other things to note for international car rentals are:

• Age restrictions: You'll need to be 25 or over in many countries to rent a car. If you're younger than that, it may still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to the types of vehicles available to rent.
• Driving limitations: Make sure you read the fine print before getting behind the wheel. Usually, you can't cross country borders, drive onto ferries or on certain types of rugged terrain with your rental car.
