At a Thai traffic stop you have fewer procedural protections than you would at home and no automatic right to an interpreter, a lawyer or a phone call — a traffic ticket is an administrative matter, not an arrest. What you do have is more useful than most visitors realise: the law sets out exactly what an officer may require, exactly what an officer may not do, and exactly what a lawful outcome looks like. Since 20 September 2019 that list has not included keeping your driving licence, and it has never included taking money at the roadside.
The practical version is simple. You are entitled to be told what offence is alleged and to be given the written ticket that the Act provides for. You are entitled to keep your licence. You are entitled to pay the fine through an official channel rather than on the spot. And where you cannot make yourself understood, 1155 puts an English-speaking police officer into the conversation.

What an officer may lawfully require
The Land Traffic Act is specific, and the list is short.
What the law says
Section 142. A traffic officer or competent official may order the driver to stop the vehicle where the vehicle does not comply with section 6, or where the officer finds that the driver or a person in the vehicle is breaching this Act or the law concerning that vehicle. Where there is reasonable ground to believe the driver has breached section 43(1) or 43(2), the officer shall order the driver to undergo a test; where the driver refuses, the officer may detain him for an appropriate period as necessary to complete the test.
Section 140. Where an officer finds a breach, the officer may give a warning or issue a traffic ticket requiring the payment of a determined penalty fine.
Section 143. Where a vehicle does not meet the section 6 requirements, the officer may order the owner or driver in writing to have it repaired.
So: that you stop; that you produce a driving licence and a copy of the vehicle registration; that you submit to a breath or drug test where there is reasonable ground; and that a defective vehicle is repaired, by written order. Failing to stop or to be tested is its own offence under section 154, with a fine not exceeding 1,000 baht — roughly £23 / US$30 / €26 — each time.
What an officer may not do
Keep your driving licence. The roadside seizure power was removed by the Land Traffic Act (No. 12), in force from 20 September 2019. The old system — licence held, substitute receipt valid as a temporary licence for up to seven days, licence passed to the investigating officer within eight hours — is gone. This is the single most out-of-date claim in circulation about driving here, and correcting it is worth more to a foreign driver than anything else on this page.
Require the original document. Since the same date you may produce your licence, a photocopy of it, or electronic licence information. Carrying a copy and leaving the original in the hotel is a perfectly proper arrangement.
Take payment at the roadside. Section 140 provides for a warning or a ticket. Section 141 provides for payment at the place named on the ticket or a place gazetted by the Commissioner-General, and says that on payment the case is deemed settled. There is no roadside cash mechanism in the Act at all. Informal roadside payments: what travellers report deals with the gap between that and what visitors describe.
Hold your passport. A traffic stop concerns the vehicle and your entitlement to drive it. A photocopy of the photo page and entry stamp is worth carrying; the original is safer left behind.
What to ask for, and how
Tone does more work here than assertion. A driver who stays calm, polite and quiet gets a materially better encounter than one who starts quoting sections. Ask for things; do not demand them.
- "What is the offence, please?" You are entitled to know what is alleged, and it belongs on the ticket in any case.
- "Could I have the ticket, please?" The written ticket is what section 140 provides for. Asking for it is asking for the normal thing.
- "Which station should I pay at?" A practical question with a practical answer, and it puts the encounter onto the documented track.
- "May I call the tourist police to translate?" Reasonable, and usually welcomed by an officer who is also struggling with the language barrier.
Do not argue about whether you committed the offence. The roadside is not where that is decided and nothing is gained by trying. If you genuinely dispute the allegation, the station named on the ticket is the place — and remember that paying settles the case under section 141, so pay only when you are content to close it.
Save 1155 before you need it. The tourist police hotline runs 24 hours with English-speaking officers and multilingual support. They are part of the Royal Thai Police, so they cannot cancel a ticket — but putting an English-speaking officer into a conversation between two people who cannot understand each other changes it completely. Tourist police in Thailand sets out what they can and cannot do.
Where a traffic matter ends and something else begins
This distinction matters more than any other on this page, because the two situations call for entirely different behaviour.
A traffic matter is a ticket. It is administrative, it is settled by payment, and section 141 closes it. Most of what a visitor will ever meet lives here.
Everything else — detention, arrest, a criminal allegation, an incident involving injury — is not. Section 140 expressly excludes drink-driving, drug-driving, failing to stop and assist after a collision and street racing from the ticket system; those go to an investigating officer and then to a court, which can also suspend or revoke a licence. Section 142 lets an officer detain a driver who refuses an impairment test for as long as necessary to complete it, and refusing without reasonable justification creates a legal presumption that you were over the limit. If you find yourself in that territory, this page is no longer the right reference: what happens if you are arrested after a crash and your embassy's consular service are.
Refusing a breath test is not a right and is not a strategy. Section 142 creates a presumption of guilt where a driver refuses without reasonable justification, and the Royal Thai Police confirmed in 2026 that they treat refusal as equivalent to drink-driving with the same penalties. There is no lesser "failure to provide" offence here to fall back on. See refusing a breath test in Thailand.
After a collision
The rules change again when there has been a crash, and it is worth knowing the shape of it in advance. Failing to stop and assist is a serious offence carrying up to three months' imprisonment and a fine of 2,000 to 10,000 baht, rising to up to six months and 5,000 to 20,000 baht where serious injury or death results — and it cannot be dealt with by ticket. Insurance surveyors, not police, usually decide fault between vehicles in Thailand. What to do after a road accident in Thailand and should you call the police after a crash are the pages for that.
Your embassy, and what it can and cannot do
Consular assistance is not legal representation. An embassy will not pay a fine, will not get you out of a police station, and will not intervene in a Thai legal process. What it can do is contact family, provide a list of local lawyers and interpreters, and check on your welfare in detention. Worth knowing before you need it rather than after.
Frequently asked questions
Do I have a right to an interpreter at a traffic stop?
Not as such. A traffic ticket is administrative and there is no interpreter service attached to it. What exists in practice is 1155, which reaches an English-speaking officer of the same force. Interpretation becomes a live legal issue only if a matter moves beyond a ticket into detention or a criminal allegation.
Can they take my licence if I refuse to pay?
No. The roadside seizure power was abolished on 20 September 2019. A court can suspend or revoke a licence after conviction for a serious offence — for drink-driving it must — but that is a different process entirely.
Am I allowed to film or record the encounter?
We are not going to tell you it is safe or lawful to do so, because that turns on Thai law we have not been able to verify and on the individual situation. What is safe to say is that escalating a stop rarely helps a visitor, and that the documents — the ticket and the receipt — are the record the system itself runs on.
Can I refuse to get out of the car?
Section 142 gives a clear power to order a driver to stop; whether you can be required to leave the vehicle is a different question and turns on what is happening. Refusing a lawful instruction converts a small matter into a large one, and there is nothing a visitor gains by it.
What if I do not have my licence with me?
Failing to produce a licence is a lesser matter than not holding one at all — the fine is up to about 1,000 baht. Not holding the right entitlement is a bigger problem, mostly for insurance reasons. See stopped without a licence in Thailand.
Should I sign anything I cannot read?
Ask what it is first, and ask for the English or for 1155 if the answer is not clear. A traffic ticket is a demand for payment rather than a confession, but a document you cannot read at all is a document worth pausing over.
Are foreigners treated differently?
The fine schedule under section 140 attaches to the offence, not to nationality. Foreign drivers do consistently report being stopped more often in tourist areas, which is a different matter and is not something anyone can source to an official document — treat it as the reported experience it is.
