When you need an International Driving Permit, what credit card rental coverage usually excludes, and how to decide on the excess insurance offered at the rental counter.
You land in Rome, walk to the rental desk and hand over your US license and credit card. The agent asks for your International Driving Permit, then offers “super coverage” for 28 euros a day to reduce your excess from 1,800 euros to zero. You have about thirty seconds to decide on two things you did not research.
Renting a car abroad is mostly straightforward, but the paperwork and insurance questions catch many travelers off guard. This guide covers what you need before you reach the counter.
Key Takeaways
- Many countries require an International Driving Permit alongside your home license, and some rental agencies insist on one even where the law is unclear.
- In the US, IDPs are issued only by AAA and the American Automobile Touring Alliance; buy before you leave.
- Credit card rental coverage often excludes certain countries, vehicle types and long rentals, and rarely includes liability.
- Counter “super coverage” removes the excess but is expensive; standalone excess insurance bought in advance is often cheaper but means paying first and claiming later.
Do you need an International Driving Permit?
An International Driving Permit (IDP) is a translation of your home license into several languages, recognised under international road traffic conventions. It is not a license on its own; you must carry it with your actual license.
Requirements vary by country. Some, such as Italy, Spain, Greece and Japan, require visitors from many non-EU countries to carry an IDP. Others accept a foreign license alone for short visits. Rental agencies may also have their own policies, and police can fine drivers who lack a required permit.
Japan has a specific requirement: it recognises IDPs issued under the 1949 Geneva Convention, and drivers from some countries need an official translation of their license instead. Check the current rules for your nationality before you travel.
In the United States, IDPs are issued only by AAA and the American Automobile Touring Alliance. They are inexpensive, valid for one year, and can be obtained in person or by mail. Be cautious of websites selling “international driver’s licenses” — these are not valid IDPs.
The rental agreement basics
Before you sign, understand three terms:
- Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW): reduces your liability for damage to the rental car, but usually leaves an excess (deductible) you still owe — often 1,000 to 3,000 euros in Europe.
- Theft Protection: similar, for theft of the vehicle.
- Third-party liability: covers damage you cause to other people and property. In much of Europe, basic liability is legally required and included in the rental price. In other regions it may not be.
The excess is the key number. If you damage the car, the rental company will charge your card up to that amount.
What credit card coverage usually leaves out
Many credit cards offer rental car coverage if you decline the rental company’s CDW and pay with that card. It can be valuable, but it has common limitations:
- Excluded countries. Some cards exclude rentals in certain countries, often including Ireland, Israel and Jamaica. Check your card’s current list.
- Excluded vehicles. Expensive cars, vans, trucks and some SUVs are often excluded.
- Rental length limits. Coverage often ends after 15 or 31 consecutive days.
- Liability. Card coverage almost never covers injury or damage to other people.
- Secondary vs primary. Secondary coverage pays only after your personal auto insurance, which may not apply abroad anyway.
Some rental companies, particularly in countries where card coverage is less accepted, may require you to buy their CDW regardless, or place a large hold on your card if you decline. Call your card issuer before you travel, ask for a letter of coverage, and bring it with you.
Should you buy the counter’s excess cover?
Rental counters often offer “super CDW” or “zero excess” products that reduce your excess to nothing. They are convenient — if something happens, you hand back the keys and walk away — but can cost as much as the rental itself on a long trip.
Alternatives:
- Standalone excess insurance bought before you travel from an independent insurer can cost much less per day. If you have an accident, you pay the rental company’s excess first and then claim it back from the insurer.
- Annual excess policies can make sense if you rent several times a year.
- Relying on your credit card, if it covers the country and vehicle.
Whichever you choose, the rental company will usually place a hold on your card for the excess amount if you decline its own cover. Make sure your card limit can handle it.
At the counter and on the road
- Inspect the car before leaving. Photograph or video every panel, the wheels and the windshield, including existing damage, with the time visible.
- Check the fuel policy. “Full to full” is usually cheapest; prepaid fuel options rarely are.
- Ask about tolls and vignettes. Some countries require a toll sticker or electronic toll account for motorways.
- Learn local rules. Speed cameras, low-emission zones and restricted city centres can generate fines months later.
- Return during office hours if possible so the car can be inspected with you present.
Frequently Asked Questions
Is an IDP the same as an international driver’s license? No. Only the IDP is officially recognised. “International driver’s licenses” sold online are not valid substitutes.
Can I drive in Europe with my US license alone? In some countries for short stays, yes. In others, an IDP is required. Rental companies may require one regardless.
Does my US auto insurance cover me abroad? Usually not outside the US and Canada. Check your policy.
What if the rental company finds damage after I return the car? Your check-out photos and a signed return inspection are your best evidence. Dispute charges promptly in writing.
The bottom line
Get an IDP before you leave if your destination or rental company requires it, confirm what your credit card actually covers in that country, and decide on excess cover before you reach the counter. Thirty seconds of pressure at the desk is much easier to handle when the decision is already made.
