Everything you need to know about international driving permits: what they are, how to get one, how to use it correctly, and how requirements vary by country.
An international driving permit (IDP) — often searched for as an "international driving license" — is a translation booklet or card that restates the details on your domestic driver's license across several major world languages. It exists to solve a specific, practical problem: a police officer or rental agent in another country may not read your home country's language or script, and a translated version gives them a fast, familiar reference point.
The modern format traces back to international road traffic conventions from the 20th century, which established a standardized layout so a license issued in one country would make more sense elsewhere. Crucially, the document is a companion to your domestic license, not a substitute for it — the two are meant to be carried and shown together.
Getting an international driving permit is generally a short process: provide your personal details, upload a clear photo of your current, valid domestic driver's license, and choose how quickly you need your documents. Most applications are reviewed the same day, with a digital copy delivered by email and a physical card following by mail for situations where a printed document is expected.
A few things are worth checking before you apply: that your domestic license is current and not close to expiring, that your name and details match your license exactly, and that you understand the validity window of the document you're purchasing so it covers your full trip.
An international driving permit only does its job when it's shown alongside your original, valid domestic driver's license — never on its own. At a rental counter, expect to present your passport, your domestic license, and your international driving permit together. Keep all three in the same place while traveling so you're not searching for one at the counter.
If you're stopped by traffic authorities while driving abroad, the same principle applies: present your domestic license first, with the international driving permit as the supporting translation. It's a good idea to also keep a digital photo of both documents saved to your phone and email as a backup.
How strictly an international driving permit is expected — and whether it's expected at all — differs from country to country and can change over time. Some destinations lean on it heavily as a standard rental requirement; others accept a domestic license alone, particularly if it's already in a widely spoken language. Entry, driving, and car-rental requirements can change and vary by destination. Always confirm current rules with the relevant embassy, consulate, or local authority before you travel.
