For many visitors, an International Driving Permit (IDP) is one of the most misunderstood travel documents. Some believe it replaces their driving licence. Others assume they can drive legally in Thailand using only their domestic licence. Neither is correct.
An International Driving Permit is simply an internationally recognised translation of your domestic driving licence. It allows police officers and authorities in another country to understand the categories of vehicle you are legally entitled to drive.
It is not a driving licence and cannot be used on its own. You must always carry it together with your original valid driving licence.
1. What Is an International Driving Permit?
An International Driving Permit (IDP) is issued in your home country before you travel.
It translates the information contained on your driving licence into multiple languages using internationally recognised formats agreed under road traffic conventions.
Thailand recognises International Driving Permits issued under the appropriate international convention. The type of IDP required depends on the issuing country, so always check the advice provided by the authority that issues driving permits in your home country before travelling.
2. Who Needs an IDP?
If you intend to hire or drive a vehicle in Thailand as a visitor, you should assume that you will need:
- Your original driving licence.
- A valid International Driving Permit where required.
- Your passport if requested.
Although some visitors report driving without ever being asked to produce an IDP, that does not change the legal requirements.
The fact you are not stopped does not make the journey legal.
3. An IDP Does Not Replace Your Licence
This is probably the most common misunderstanding.
Your International Driving Permit is only valid when presented together with your original driving licence.
If you lose your domestic licence or leave it at your hotel, your IDP becomes invalid.
Likewise, if your home driving licence has expired, the International Driving Permit is no longer valid, even if the permit itself has not yet expired.
4. Motorcycle Entitlement
An International Driving Permit only reflects the driving categories shown on your original licence.
If you do not hold a full motorcycle entitlement in your home country, your IDP will not authorise you to ride a motorcycle in Thailand.
This catches many visitors by surprise, particularly those hiring small scooters in tourist areas. Hiring companies may not always check your entitlement carefully, but responsibility remains with the rider.
Riding Without Motorcycle Entitlement
If you are involved in a collision while riding without the correct licence category, your insurance provider may refuse to meet the costs of any claim.
5. Rental Companies
Rental companies have their own internal procedures.
Some will insist on seeing an International Driving Permit before releasing a vehicle. Others may only ask for your passport and driving licence.
Regardless of what a rental company accepts, the legal responsibility always rests with the driver.
Always ensure you meet Thailand's legal driving requirements before accepting the keys.
6. Police Checkpoints
If you are stopped at a police checkpoint, officers may ask to see:
- Your passport or identification.
- Your home driving licence.
- Your International Driving Permit where applicable.
- Vehicle registration documents if required.
Having your documents organised and readily available usually makes the process quick and straightforward.
7. Common Mistakes
Avoid these common errors:
- Assuming your domestic driving licence is enough.
- Carrying an IDP but leaving your original licence behind.
- Riding a motorcycle without motorcycle entitlement.
- Believing the rental company is responsible for checking legality.
- Assuming insurance will pay regardless of your licence status.
8. International Driving Permits Issued in Thailand
The information above relates to visitors bringing an International Driving Permit to Thailand. However, the reverse is also true.
If you live in Thailand and hold a valid Thai driving licence, you may be eligible to apply for an International Driving Permit issued by the Department of Land Transport (DLT). This permit allows Thai licence holders to drive temporarily in many countries that recognise the relevant international road traffic conventions.
This is particularly useful for foreign residents who have exchanged their home driving licence for a Thai licence or have obtained a Thai driving licence after moving to Thailand.
Like all International Driving Permits, the Thai-issued IDP is not a driving licence in its own right. It must always be carried together with your valid Thai driving licence and presented whenever requested by the authorities in the country you are visiting.
Before travelling overseas, you should always confirm:
- That your destination country recognises International Driving Permits issued in Thailand.
- Which international convention applies to your destination.
- Whether any additional local driving requirements exist.
Applications are made through the Department of Land Transport. Requirements may vary slightly depending on your circumstances, but applicants are generally required to provide:
- A valid Thai driving licence.
- Passport.
- Passport photographs.
- Completed application form.
- Applicable government fee.
As with all driving documentation, requirements and recognised countries can change over time, so always verify the latest guidance before travelling.
