What an International Driving Permit actually is.

Definition

An International Driving Permit (IDP) is a multilingual document issued under the authority of the United Nations conventions on road traffic — the 1949 Geneva Convention and the 1968 Vienna Convention. It is, in practical terms, a translation of your domestic driver's license into multiple official languages, bound into a small booklet that meets UN formatting standards.

It is not a standalone license. It is not issued by your home government, and it has no validity if your original domestic license is suspended, expired, or absent. Always carry both documents while driving abroad.

The two conventions

There are two competing UN frameworks. The 1949 Convention is older and remains in force in countries like the United States, Japan and India. The 1968 Convention is newer, broader, and used across most of Europe, Latin America and Asia. Some countries have ratified both. A few have ratified neither.

Anatomy of the booklet

A standard IDP is the size of a passport (148 × 105 mm) with a grey cover. Inside it contains:

• Translation of your name, photo, license number and date of issue into multiple languages — including Arabic, Chinese, English, French, German, Italian, Japanese, Portuguese, Russian, and Spanish.
• A categorisation of the vehicle classes you are permitted to drive (A motorcycles, B passenger cars, C trucks, D buses, E trailer combinations).
• Issuing authority, validity period, and a unique permit number for verification.

What it lets you do

• Rent cars, motorcycles and campervans abroad
• Drive your own vehicle across borders (e.g. road-tripping the EU on a US license)
• Present a readable driving credential at police checks and traffic stops
• Satisfy travel insurance requirements that you are “legally licensed to drive”
• Use as a backup photo ID at hotels, scooter rentals, and SIM-card desks

What it doesn't do

• Replace your domestic license — they must be carried together
• Grant new driving privileges (if your domestic license only covers cars, your IDP only covers cars)
• Function as a passport, visa or government-issued ID for immigration purposes
• Allow you to drive in the country that issued your domestic license

A quick history

The first international driving certificate was issued in 1909 as part of the Paris Convention on motor traffic. Modern IDPs trace back to 1949, when nations met in Geneva to standardise road signs, license formats and traffic rules in the aftermath of World War II. The 1968 Vienna Convention modernised and expanded the framework. Together they govern how millions of travelers drive across borders every year.
