Five questions decide whether you are legally on the road in Thailand, and you need a clean answer to all five. They are not equally consequential: the first is where most visitors come unstuck, and it is the one that decides whether your insurance responds after a crash.
Work through them in order. Where an answer is no, the fix is set out underneath.
- Questions to answerFive, all of them yes
- The one that catches peopleMotorcycle entitlement on a car licence
- The one you cannot fix hereThe international driving permit
1. Does your own licence cover this vehicle?
Not "do you have a licence". Does the licence in your wallet carry entitlement for the category of vehicle you are about to get on? For a car, almost certainly yes: category B on a European licence, or an ordinary state or provincial licence elsewhere, covers a normal hire car.
For anything on two wheels, only if your licence carries motorcycle entitlement. Thailand issues Private Car and Private Motorcycle licences as separate documents under section 43 of the Motor Vehicle Act. The conventions carry motorcycles as category A, a single category covering everything from a 50cc scooter upwards. And Thailand declared under Article 54(2) of the 1968 Vienna Convention that it treats mopeds as motorcycles, which removes the last possible argument.
There is no engine size small enough. A 110cc twist-and-go scooter is a motorcycle for licensing and insurance purposes. It does not matter that it has no gears, that the shop handed it over without looking, or that nobody has asked to see your licence. The entitlement exists on your licence or it does not, and that is exactly what a claims assessor looks at. See the Thai motorbike licence and engine sizes.
If the answer is no: hire a car instead, use local transport, add motorcycle entitlement at home before your next trip, or take a Thai motorcycle licence if you are staying long term. There is no version of this that is fixed by riding carefully.

2. Do you have the right International Driving Permit?
Thailand is a party to both the 1949 Geneva and the 1968 Vienna conventions, so the correct permit depends on your nationality — and both answers are right for different readers.
| Where your licence is from | Which IDP you can get |
|---|---|
| UK, Germany, France, Italy, Netherlands, Spain, Portugal, Poland, Switzerland, Austria, Norway, Sweden, Denmark, Finland | The 1968 permit. These countries are 1968 parties. |
| United States, Australia, Ireland, Canada, New Zealand, Japan | The 1949 permit, because their own countries are not 1968 parties and cannot issue a 1968 one. That is the correct document for them, and Thailand remains bound to the 1949 Convention in its relations with those states. |
A 1949 permit is valid for one year from issue; a 1968 permit for three years, or until your domestic licence expires if that is sooner. An IDP is never a licence on its own — Article 41(5) of the 1968 Convention says it is issued only to the holder of a domestic permit and ceases to be valid when that permit does. Carry both together, and note that it cannot create entitlement you do not have.
You will read online that an IDP is "valid in Thailand for 90 days". We looked for a statutory or Department of Land Transport basis and found none — neither convention contains such a rule, and Thailand entered no reservation creating one. Do not plan around it.
This is the one you cannot fix after you land. The UK government's wording is blunt — "You cannot buy an IDP outside the UK, so get one before you travel" — and the same principle applies in every issuing country. Websites selling "international driving licences" to people already abroad are not issuing the real document. The International Driving Permit for Thailand explains where to apply.
If the answer is no: and you are already here, you are relying on the argument that your domestic licence should be recognised on its own. As treaty law, a driver from a 1968 party holding a conforming photocard licence is entitled to recognition, and the Department of Land Transport said as much in 2021. As practical advice, the UK Foreign Office still tells British drivers to carry the 1968 IDP, rental companies ask for one, and insurers condition cover on holding a licence valid for the country you are driving in. Do not treat the absence of an IDP as safe. See which licence can I use in Thailand.
3. Are you old enough — for the law and for the rental company?
These are two different numbers and both have to work. Thai minimum ages are reported as 18 for a private car and 15 for a motorcycle on a restricted basis, with full motorcycle entitlement from 18. Separately, under Article 41(2) of the 1968 Convention a contracting state may refuse to recognise an international permit held by anyone under 18.
The rental company's minimum age is a commercial decision and is usually higher — frequently 21 or 23 for a car, sometimes with a young-driver surcharge and a minimum period since your licence was issued. Both numbers are covered in the Get Started and Renting sections.
4. Is the vehicle itself legal?
You can be perfectly entitled and still be on a machine that has no business being on the road. UK government advice is worth quoting because most readers have never heard it: motorcycles and scooters for hire in tourist areas "are often unregistered and cannot be used legally on a public road." A machine that cannot legally be on the road cannot legally be ridden by anyone, whatever licence the rider holds.
- Registration plate fitted and matching the paperwork.
- A copy of the registration document in the vehicle — ask for it if it is not there.
- Current compulsory insurance (Por Ror Bor). A vehicle cannot be legally taxed without it.
- Current annual tax, and for older vehicles a current inspection.
- Working lights, brakes and horn. Section 6 of the Land Traffic Act requires a vehicle to be in a condition that endangers nobody.
You cannot verify a Thai registration book if you cannot read Thai, which is a strong argument for renting from an established operator rather than a beach stall.
5. Are you actually insured for what you are about to do?
Legality and cover are separate questions, and the second has more money attached. Even a fully entitled driver can be outside cover on an engine-size clause, a helmet condition, a riding-surface exclusion or the alcohol exclusion.
Open your policy wording — the full PDF, not the certificate — and search it for motorcycle, moped, scooter, licence, engine, helmet and pillion. The clause usually requires a home licence covering that class of vehicle plus a licence valid for the country you are riding in. At least one insurer adds "regardless of the local laws", applying its own licensing test whether or not Thai police would have stopped you. Does travel insurance cover driving in Thailand and what voids your motorbike cover go through it.
The UK Foreign Office states the consequence in one sentence. Driving a car or riding a motorcycle in Thailand without a valid licence "could invalidate your travel insurance and you'll be unable to claim if you have an accident or injury." Everything else on this page is paperwork. That is the part that decides who pays for a hospital.
What to carry, once all five are yes
- Your home licence and your IDP, together — the permit is worthless without the licence whose number is written in it.
- A copy of the vehicle registration document, and the rental agreement.
- Passport, or a good copy of the photo and visa pages. Do not leave the passport itself as a deposit.
- Your insurer's 24-hour assistance number, saved offline.
- 1155, the Tourist Police hotline, which reaches an English-speaking officer.
A useful thing to know at a checkpoint: since September 2019 a driver in Thailand may produce the licence, a photocopy of it, or electronic licence information, and a traffic officer no longer has the power to confiscate a licence at the roadside.
If you would rather answer these questions interactively, the licence checker walks through the same logic and tells you what you need.
Frequently asked questions
Can I drive in Thailand on my home licence alone?
There is a real argument that a conforming licence from a 1968 Convention country must be recognised, and the Department of Land Transport said in 2021 that such licences can be used here. But the UK government still tells its citizens to carry the 1968 IDP as well, rental desks ask for one, and insurers condition cover on a licence valid for the country you are driving in.
How long is an IDP valid in Thailand?
A 1949 permit is valid for one year from issue; a 1968 permit for three years from issue or until your domestic licence expires, whichever is earlier. The widely repeated "90 days in Thailand" rule has no statutory or Department of Land Transport basis that we could find, and we will not repeat it.
Does an IDP let me ride a motorbike if my licence is car-only?
No. An IDP restates the categories on your domestic licence. If there is no motorcycle entitlement on the licence, there is none on the permit, and no amount of paperwork creates it.
I hold an ASEAN licence. Do I need an IDP?
Under the 1985 ASEAN agreement, a licence holder from an ASEAN country on a temporary stay in another may drive the classes their licence permits, with a certified English translation if it is not in English. A rental desk telling a Malaysian or Singaporean driver they need an IDP is not describing the agreement.
What is the penalty if I get this wrong?
Riding without a licence is reported as up to a month's imprisonment and/or a fine of up to about 1,000 baht under the Motor Vehicle Act. That is not the reason to care. Riding without a licence in Thailand explains what happens afterwards.
