What Is an International Driving Permit (IDP)?
An International Driving Permit (IDP) is an official, multilingual translation of your national driving licence that lets local authorities and rental companies abroad understand your driving entitlements. It does not replace your licence and is never valid on its own: you must carry both your original licence and the IDP together. Issued under United Nations road traffic conventions, an IDP translates your licence details into multiple languages so you can be understood at the roadside in countries that recognise it.
What an IDP actually is
An International Driving Permit is a standardised booklet (or, with International Drivers, a digital equivalent) that restates the information already on your home driving licence in several languages. It records your name, photo, the categories of vehicle you are licensed to drive, and the issuing country, so an officer or rental agent who cannot read your native licence can still verify what you are permitted to drive.
Crucially, an IDP carries no driving privileges by itself. Your legal right to drive comes from your underlying national licence; the IDP simply makes that licence intelligible across borders. If your home licence is suspended or expires, your IDP becomes meaningless at the same moment.
The conventions behind it
IDPs exist because of two international treaties: the 1949 Geneva Convention on Road Traffic and the 1968 Vienna Convention on Road Traffic. Countries that have signed one or both agree to recognise the corresponding IDP format alongside a valid national licence.
Because there are two convention formats, the IDP that a country accepts can depend on which treaty it follows. Most travellers never need to worry about the detail, but it is worth checking your destination's requirements before you go, since validity periods and accepted formats differ slightly between the two.
When you typically need one
You may need an IDP when driving or renting a car in a country that does not use the same alphabet or language as your licence, or where local law specifically asks foreign drivers to carry one. Many car rental companies also request an IDP as a condition of hire, even where the law is silent.
Requirements vary widely by destination and by your licence's country of issue, so the safest approach is to confirm the rules for your specific trip rather than assume. When in doubt, carrying an IDP rarely hurts and often smooths the rental and roadside experience.
How to get one
Traditionally, IDPs are issued by an authorised body in the country where your licence was issued. With International Drivers, you can complete the process online by submitting your licence details and photo, and receive a digital IDP quickly, with a physical copy available where needed.
Whichever route you choose, always carry your original national licence alongside the IDP. An IDP presented without the licence it translates is not valid for driving.
Frequently asked questions
Does an IDP let me drive without my home licence?
No. An IDP is only valid when carried together with your original national driving licence. On its own it grants no driving rights.
Is an IDP the same everywhere?
There are two main formats, based on the 1949 Geneva and 1968 Vienna conventions. The format a country accepts depends on which treaty it follows, so check your destination's requirements.
How long is an IDP valid?
Validity depends on the convention and issuer, commonly ranging from one to three years, and it can never outlast your underlying national licence.
Do I still need my regular licence with an IDP?
Yes, always. The IDP translates your national licence, so both documents must be presented together to be valid.
