What's an International Driving Permit? All You Need to Know

Planning a road trip abroad? Knowing what's an international driving permit is the first step to a hassle‑free journey.

This guide explains the purpose, requirements, and how to obtain this essential travel document.

What's an International Driving Permit?

An International Driving Permit (IDP) is a certified translation of your home driver’s licence, recognized in over 150 countries. It does not replace your national licence; you must carry both while driving overseas.

If you’re still asking what's an international driving permit, think of it as your licence’s passport.

Why You Need an IDP When Traveling

Many foreign authorities require an IDP to verify that your licence is valid and to understand its categories. Without it, you risk fines, vehicle impound, or being denied rental cars.

Remember, knowing what's an international driving permit can save you time and money at border checkpoints.

• Legal compliance: Meets local traffic regulations.
• Rental car acceptance: Most car‑rental agencies ask for an IDP.
• Police checks: Simplifies verification during roadside inspections.

Countries That Require an IDP

While the list changes, the following destinations commonly demand an IDP for non‑resident drivers:

• Australia
• Portugal
• Thailand
• United States (certain states)
• Spain

How Long Is an IDP Valid?

An IDP is typically valid for one year from the date of issue, or until your home licence expires—whichever comes first. It cannot be renewed; you must apply for a new permit when the current one ends.

How to Apply for an IDP

Applying is straightforward. You need a valid driver’s licence, two passport‑size photos, and a completed application form. Once approved, you’ll receive the IDP by mail.

What to Carry With Your IDP

When driving abroad, always have the following documents on hand:

• Your original driver’s licence.
• The International Driving Permit.
• Passport identification.
• Proof of insurance for the rented or owned vehicle.

Keeping these together speeds up any checks by local authorities.

Frequently Asked Questions

Do I need an IDP if I already have a US driver’s licence?

Many US states require an IDP for rentals or police checks abroad, so it’s safest to obtain one before you travel.

Can I use an IDP in any country?

An IDP is accepted in most countries that are party to the 1949 Geneva or 1968 Vienna conventions, but always verify the specific requirements of your destination.

How much does an IDP cost?

Fees vary by issuing authority; check with your national automobile association for the exact price.

Is an IDP the same as a foreign driver’s licence?

No. An IDP is a translation of your existing licence, not a separate licence issued by the foreign country.

What should I do if my IDP expires while I’m abroad?

You must apply for a new IDP from your home country; an expired permit is not valid for driving.
