International Driving Permits and Insurance Basics
Ever landed in a new country, picked up a rental car, and suddenly realized the fine print is in a language you barely remember from high school? Trust me, you’re not alone. Navigating the world of International Driving Permits (IDPs) and car rental insurance can feel like its own road trip—one with plenty of unexpected turns. But with a little prep (and less than 15 minutes of your time), you can avoid the classic mistakes and get rolling, worry-free.
When Do You Actually Need an International Driving Permit?
If you Google this, you’ll find a thousand opinions. Here’s the *real* answer: It depends on the country. Some places (like much of Western Europe) will rent you a car with just your US license. Others (Japan, Italy, and a surprisingly long list) legally require you to carry an IDP alongside your home license. Skip this, and you risk fines—or worse, nullifying your insurance coverage.
Quick story: On a recent trip to Portugal, my US license was technically “okay,” but the rental desk still wanted an IDP. I had one, so no problem. The couple behind me? Not so lucky. They had to scramble for taxis for two days while waiting for friends to overnight an IDP. Moral: check before you go.
Pro tip: No country accepts an IDP by itself—you always need your home license too.
How to Get an IDP (in 10 Minutes or Less)
- Go to your country’s authorized agency (in the US, it’s AAA or AATA).
- Bring two passport photos and your valid license.
- Fill out a short form. Pay the fee (usually $20 in the US).
- Walk out with your IDP—no waiting around.
Seriously, that’s it. It’s valid for a year, and you can renew if you’re still on the road.
Understanding Rental Insurance: What’s Actually Required?
This is where most people get tripped up (and where rental companies make their money).
Types of Insurance You’ll See at the Desk
- CDW/LDW (Collision/Loss Damage Waiver): Covers damage/theft of the rental car. *Not* technically insurance, but waives your financial responsibility.
- Liability: Covers damage you cause to other people or property. Sometimes included, sometimes not.
- Personal Accident Insurance: Pays for medical treatment if you’re injured. Check your health/travel insurance before buying this.
- Personal Effects Coverage: Covers belongings stolen from the car. Often redundant if you have travel insurance.
What do you actually need? At minimum, local law often requires liability. CDW/LDW is usually optional—but comes with a catch: if you refuse it, you’ll need proof of other coverage (like a credit card benefit), or they’ll freeze a huge deposit on your card.
In Italy, CDW is mandatory. In Ireland, most credit cards don’t cover rentals. Always check both the rental company policy and your card’s fine print.
Deposit Traps and Claim Nightmares: What to Watch For
Deposits vary wildly. In Spain last year, my “economy” rental put a $1,500 hold on my card because I declined their pricey insurance. In Mexico, a friend got hit with a $2,000 deposit and a multi-week fight to get it back.
How to avoid surprises?
- Check the deposit amount before you book (often hidden in the T&Cs).
- Make sure your credit limit can handle it (or use a card with a higher limit just for rentals).
- Take photos/video of the car at pick-up and drop-off. This has saved me twice from “mystery scratches.”
- Keep all paperwork (digital or paper) until your deposit is fully returned.
If You Need to File a Claim
Here’s what worked for me after a minor fender-bender in Croatia:
- Document everything. Photos, police report (if required), rental agreement, and damages.
- Notify the rental desk immediately—don’t wait until return.
- Get all charges in writing with an itemized bill.
- If using credit card insurance, file your claim online as soon as you’re home. Upload all documents.
- Follow up. Some claims take weeks, but polite persistence works wonders.
Most credit cards cover up to $50,000 in damage, but only if you decline the rental company’s CDW and pay with that card. If you’re using a travel insurance policy, the process is similar—just start as soon as you can, and keep every receipt and email.
