For most tourists, meeting Thai police means a roadside checkpoint: helmet, licence, sometimes ID. It is routine if you know what to show and how to behave. The rules below were checked on 17 October 2026 against the Immigration Act, UK Foreign Office advice and the Tourist Police website.
Do you have to carry your passport
Police are entitled to ask for your passport. The UK Foreign Office says a copy of the photo page is usually enough, but if you do not have the original on you, you may be asked to bring it to a police station within 24 hours.
The 1979 Immigration Act has no section that explicitly requires you to carry the passport at all times. Section 64, often quoted in expat chats, is actually about harbouring illegal immigrants. Section 58, however, presumes that a foreigner who cannot show evidence of lawful entry entered illegally. So the original with your entry stamp should always be within reach, even if it sits in the hotel safe.
What works in practice:
- On you: a copy or photo of the photo page and latest entry stamp, plus the visa and extension pages if you are on a long-stay visa
- The passport itself in the hotel or home safe, ready to bring if asked
- Never leave it as a deposit for a scooter, car or jet ski; it is a common pressure tactic, see common scams
- For island trips, travel between provinces and flights, take the passport with you
If you are stopped
Usually it is a road check: helmet, licence, registration, alcohol. Traffic fines went up in 2022; the full list is in our guide to Thai traffic rules. What to do, in order:
- Pull over and take off sunglasses and helmet so your face is visible. Stay calm and keep your voice down: public anger rarely helps in Thailand
- Show your licence and vehicle papers. If you do not hold the right licence category, do not argue; ask how much and where to pay
- Ask for a ticket (bai sang). Fines on a ticket are paid through the channels printed on it or at the police station, and the police run an online ticket service at ptm.police.go.th
- Keep the receipt. If the vehicle is rented, show it to the rental shop when you return it
Do not offer money yourself and do not pay without paperwork. If you are quoted a sum with no ticket, politely ask for one or call the Tourist Police on 1155.
Who to call and where to complain
| Where | Number or channel | When |
|---|---|---|
| Tourist Police | 1155, 24 hours | theft, scams, disputes, doubts about a check |
| Tourist Police complaints | form on touristpolice.go.th, info@touristpolice.go.th | complaints after the event, including about an officer |
| TAT Contact Centre | 1672 | tourist questions, where to get help |
| Your embassy | number on the embassy website | detention, lost passport, court cases |
For a complaint, note the officer’s badge number or name, the place and time, and keep photos of the ticket or messages. If something was stolen, you will need a police report for your insurance.
What not to do
- Do not carry vapes or IQOS: they are illegal in Thailand, and the UK Foreign Office says offences usually mean confiscation and a THB 5,000-30,000 fine; see vapes in Thailand
- Do not buy cannabis without a prescription, or anything else: drug penalties are severe, see drug laws in Thailand
- Do not raise your voice or touch an officer, even if you are sure you are right: ask for the ticket and sort it out later through 1155
FAQ
Can I be fined for leaving my passport at the hotel?
We found no specific fine for not carrying your passport in the Immigration Act. The UK Foreign Office says police usually accept a copy of the photo page and may ask you to bring the original to a station within 24 hours. Section 58 of the same Act, however, presumes that a foreigner who cannot show evidence of lawful entry entered illegally, so keep the original within reach.
Can I pay a fine to the officer in cash on the spot?
Traffic fines are issued on a ticket (bai sang) and paid through the channels printed on it or at the police station; the police also run an online ticket service at ptm.police.go.th. Ask for the ticket and a receipt. If someone offers to settle it without paperwork, call the Tourist Police on 1155.
What happens if police find a vape?
Possessing or using vapes and IQOS is illegal in Thailand. According to the UK Foreign Office, it usually ends with confiscation and a fine of THB 5,000-30,000, and detention and court are possible. See our vape answer for details.
Do long-stay residents need to carry their passport too?
The same rule applies: police can ask for ID, and your visa and stamps must be in order. Carry a copy of the photo page, the visa and your latest extension stamp, and keep the original safe at home.
Where can I complain about a police officer or extortion?
To the Tourist Police: the 1155 hotline, the complaint form on touristpolice.go.th and info@touristpolice.go.th. Note the officer's badge number, the place and time, and keep photos. If you are detained, ask for your embassy to be contacted.
