What an International Driving Permit is, how to get one, and whether it really lets you drive abroad
What an International Driving Permit is, how it differs from your Thai licence, the two conventions countries follow differently, a general outline of the process at the Department of Land Transport, how long it typically lasts, and what else to prepare before driving abroad.
Kurz erklärt
- An International Driving Permit (IDP) is not a licence on its own — it is a translated, certified companion document to your home-country driving licence, so a foreign official can read what it says. You still need a valid Thai driving licence with you at all times; an IDP cannot replace it.
- There are two main conventions countries follow differently: the 1949 Geneva Convention and the 1968 Vienna Convention. Which format a destination country accepts changes over time and can depend on the driver's nationality, so always confirm with that country's official road authority, or with the authority in your home country that issues the permit, before travelling — do not rely solely on a generic list found online.
- Thai citizens apply in person at the Department of Land Transport (กรมการขนส่งทางบก). In general, you will need your passport, a valid Thai driving licence and photos, but the exact documents required, fees and processing time can change, so always confirm the current requirements with the Department before travelling.
What is an International Driving Permit?
An International Driving Permit (IDP) is a document that translates and certifies the details on your home-country driving licence into a format a foreign traffic officer or car-rental clerk can read, regardless of the language they speak. Fundamentally, an IDP is not a driving licence on its own — it is a companion document that must always be used together with your actual driving licence.
How do the 1949 Geneva and 1968 Vienna conventions differ?
There is no single global standard for an IDP. Permits are issued under two different main international frameworks: the 1949 Geneva Convention on Road Traffic and the 1968 Vienna Convention on Road Traffic. Each country has chosen to join one, both, or neither of these conventions, and some countries recognise an IDP issued under one convention but not the other.
This means which IDP format a given country accepts can change over time, and in some cases depends on the driver's nationality. We are deliberately not listing which countries accept which convention in this article, because that kind of information can go out of date at any time and could mislead you if it is cited at the wrong moment. Always check with the destination country's road authority or transport ministry, or with Thailand's Department of Land Transport as the issuing authority, before finalising travel plans.
How does a Thai citizen apply for an IDP?
Thai citizens apply for an IDP in person at the Department of Land Transport (กรมการขนส่งทางบก). Here is a general outline of the steps involved. This is only a broad overview — the exact documents required, fees and processing time can change, so always confirm the latest requirements with the Department before you go.
- 11. Gather the basic documentsYou will generally need a valid passport, a valid Thai driving licence and photos in the required size. Confirm the exact details with the Department of Land Transport before you go.
- 22. Apply in person at the Department of Land TransportApplying for an IDP requires you to be there in person — someone else cannot apply on your behalf. Staff will check your documents and your Thai licence.
- 33. Pay the fee and wait to receive the permitThe fee and processing time can change based on the Department's current announcements. Some offices may issue it the same day, others may take longer. Leave a buffer before your travel date and ask in advance.
How long does an IDP last, and how do you renew it?
An IDP typically has a limited validity period counted from its issue date, and it is not tied to your Thai licence's own expiry date. It cannot be renewed while you are abroad. If it expires or is due to expire while you are travelling, the fix is to apply for a fresh one at the Department of Land Transport in Thailand once you are back — it is not a matter of "renewing" the same booklet. Confirm the exact validity period and conditions directly with the Department, since they can change.
A replacement is applied for at the same office — the Department of Land Transport — using a broadly similar process and documents to your first application, as long as your Thai driving licence itself is still valid.
What else to prepare before driving abroad
Holding an IDP alone is not enough for driving abroad to go smoothly. One thing that is easy to overlook is navigation when mobile signal or Wi-Fi is unreliable — while driving through remote areas or near borders, offline-capable maps and navigation apps matter just as much as the paperwork.
Caution: the rules vary by country and by how you are driving
Häufige Fragen
Can an IDP replace my Thai driving licence?+
No. An IDP is a translated, certified companion document that must always be used together with a valid Thai driving licence — it is not a driving licence on its own.
Which countries accept a Thai-issued IDP?+
It depends on which convention the destination country follows — the 1949 Geneva Convention, the 1968 Vienna Convention, or neither — and this can change over time or depend on the driver's nationality. This article does not list specific countries because that information can go out of date easily. Always check with the destination country's road authority or Thailand's Department of Land Transport before travelling.
What documents do I need for an IDP, and how long does it take?+
In general you need a passport, a valid Thai driving licence and photos, but the exact documents, fees and processing time can change based on the Department of Land Transport's current announcements. Confirm the latest requirements before you go.
My IDP expires while I am abroad — what do I do?+
You cannot renew an IDP from abroad. You need to apply for a new one at the Department of Land Transport once you are back in Thailand, provided your Thai driving licence is still valid.
Do I always need an IDP to rent a car abroad?+
It depends on that country's rules and the rental company's own conditions, which can differ from the general driving rules of the same country. Confirm directly with the rental company and the relevant insurer before you travel — do not assume based on another country or a previous trip.
