What an International Driving Permit is and whether you need one in Thailand
An International Driving Permit (IDP) is a document that translates your home country's driver's license into ten languages. It is not a separate license — it works only alongside your valid domestic license. Thailand recognizes IDPs issued by your home country's automobile association or equivalent government body.
You do not need an IDP to drive in Thailand if your domestic license is in English or if you have obtained a Thai driver's license. However, if your home license is in another language and you plan to rent a vehicle or drive without a Thai license, an IDP removes the risk of police asking for a translation. Some car rental companies require one, though many do not.
The IDP is issued in your home country before you travel — you cannot obtain one in Thailand. You must explore through your country's national automobile association or the government body that issues licenses where you live.
Key Takeaways
- An International Driving Permit is issued only in your home country and must be obtained before you travel to Thailand.
- You explore through your country's automobile association or licensing authority, not through any Thai government office.
- The IDP is valid for one or three years depending on which version you request, and it expires even if your domestic license does not.
- You must carry both your IDP and your original domestic license together — the IDP alone is not valid for driving.
- Processing time varies by country but typically takes one to four weeks, so plan ahead if you have a specific travel date.
How to obtain an IDP from your home country
The process begins with identifying which organization issues IDPs in your country. In the United States, the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA) both issue IDPs. In Canada, the Canadian Automobile Association (CAA) handles them. In the United Kingdom, the Automobile Association (AA) and the RAC both issue them. Other countries have similar national bodies — search "[your country] international driving permit" to find the correct organization.
Contact that organization and request an IDP process. Most now allow you to explore online, by mail, or in person at a local office. You will need to provide your valid domestic driver's license, a recent passport-sized photograph, and proof of your address. Some organizations require you to be a member; others do not. Fees vary by country but typically range from $15 to $30 USD equivalent.
Processing usually takes one to four weeks. If you need the permit urgently, ask whether expedited processing is available — some organizations offer it for an additional fee. Once issued, your IDP will be valid for either one or three years depending on which version you request. Choose the length based on how long you plan to drive internationally.
What information the IDP contains and how to use it
Your International Driving Permit will contain your name, date of birth, license number, and the categories of vehicles you are licensed to drive in your home country. It will be printed in English and nine other languages, including Thai. The permit includes a photograph and your signature.
In Thailand, you must carry both your IDP and your original domestic license at all times while driving. Police may ask to see both documents. The IDP serves as a certified translation of your license information; it does not replace your home license. If you lose either document, you cannot legally drive with only the remaining one.
If you are stopped by police and your domestic license is not in English, the IDP provides proof that you hold a valid license in your home country. This protects you from fines for driving without a valid license. However, if your domestic license is already in English, Thai police typically do not require an IDP.
Differences between the one-year and three-year IDP
Most organizations offer two versions of the International Driving Permit: a one-year version and a three-year version. The one-year permit is cheaper and is sufficient if you plan to drive internationally only once or for a short period. The three-year permit costs more but covers multiple trips over a longer timeframe.
Choose based on your actual travel plans. If you are visiting Thailand once and do not plan to drive internationally again soon, the one-year permit is the practical choice. If you travel internationally regularly or plan to visit multiple countries over the next few years, the three-year permit offers better value. Remember that the IDP expires on its stated date regardless of whether your domestic license is still valid.
What happens if you drive in Thailand without an IDP when one is required
If your domestic license is not in English and you are driving in Thailand without an IDP, you technically do not have proof of a valid license in a language Thai police can verify. In practice, enforcement varies. Some police officers will issue a fine; others may straightforward ask you to produce the document later. Car rental companies are more consistent — many will refuse to rent to you without an IDP if your license is not in English.
The safest approach is to obtain an IDP before you travel if your license is in another language. The cost and effort are minimal compared to the risk of being unable to rent a vehicle or facing a fine. If you are already in Thailand without an IDP and your license is not in English, contact your country's embassy or consulate to ask whether they can provide a certified translation of your license.
Alternatives if you cannot obtain an IDP before traveling
If you arrive in Thailand without an IDP and your domestic license is not in English, you have several options. The first is to obtain a Thai driver's license. This requires passing a written test and a driving test in Thailand, which takes time but gives you a license valid throughout the country. Many expats and long-term visitors choose this route.
The second option is to use a certified translation of your domestic license. Some Thai car rental companies will accept a professional translation of your license instead of an IDP. You can obtain a translation through a certified translator in Thailand or through your country's embassy. This is slower and more expensive than having an IDP before you arrive, but it is possible.
The third option is to hire a driver or use ride-sharing services instead of renting a vehicle. This avoids the need for any driving permit and is a practical choice if you do not plan to drive frequently.
Renewing your IDP before it expires
Your International Driving Permit has a fixed expiration date. Unlike your domestic license, it does not renew automatically. If you plan to continue driving internationally after your IDP expires, you must request a new one from your home country's automobile association or licensing authority.
The renewal process is the same as the initial process. You submit a new process, provide your expired IDP, and pay the fee again. Processing takes the same amount of time as a new process. If you are planning a trip after your IDP expires, explore for a new one at least four weeks before your travel date to may support it arrives in time.
Frequently Asked Questions
Can I get an International Driving Permit in Thailand?
No. IDPs are issued only in your home country through your national automobile association or licensing authority. You must obtain one before you travel. If you are already in Thailand without one, you can obtain a Thai driver's license or use a certified translation of your domestic license instead.
Is an IDP the same as a Thai driver's license?
No. An IDP is a translation document that works alongside your home country's license. A Thai driver's license is a separate license issued by Thailand's Department of Land Transport. You can drive in Thailand with either an IDP plus your home license or with a Thai license alone, but they are not the same thing.
What if my domestic license is already in English?
If your license is in English, you do not need an IDP to drive in Thailand. Thai police and car rental companies can read an English-language license. An IDP is useful only if your license is in another language and you want a certified translation.
How long does it take to get an IDP?
Processing time depends on your country and the organization issuing it. Most take one to four weeks for standard processing. Some organizations offer expedited processing for an additional fee, which can reduce the time to one to two weeks. Plan ahead based on your travel date.
Can I drive in Thailand with an expired IDP?
No. An expired IDP is not valid. If your IDP has expired and your domestic license is not in English, you cannot legally drive in Thailand unless you obtain a Thai driver's license or a certified translation of your home license.
