Stop. Check whether anyone is hurt. If anyone is, call 1669 for an ambulance before you do anything else. Then leave the vehicles where they are, call the police or the Tourist Police on 1155, and telephone your rental company or your insurer so that they can send a surveyor to the scene. You do not exchange details and drive away in Thailand. You wait.

That last sentence is the part visitors get wrong, because it is the opposite of what most of us are taught at home. In Thailand a motor claim is normally settled at the roadside, that afternoon, by claims surveyors sent out by the two insurers, working from the positions of the vehicles and what the police say. If you drive off before that happens, you have walked away from the only process that decides who pays.

Do not leave the scene. Stopping, giving assistance and identifying yourself after a collision is a criminal duty under the Land Traffic Act, not a courtesy. It is also one of the few traffic offences that cannot be dealt with by an on-the-spot ticket — it goes to an investigating officer and to a court. Riding away from a crash you caused, however small it looked, is the single worst decision available to you.

The order to do things in

Work down this list. It is written so that the most urgent thing is always at the top, and so that you can follow it on a phone screen with your hands shaking.

  1. Stop, and stay stopped. Switch the engine off. On a bike, get it and yourself out of the traffic stream if you can do it in a few seconds; in a car, put the hazard lights on.
  2. Check yourself, then everyone else. Adrenaline hides injuries for ten or fifteen minutes. Look for bleeding, obvious deformity, and anyone who is confused or not fully conscious.
  3. Call 1669 if anyone is injured — you, a passenger, the other driver, a pedestrian. It is the national emergency medical number, it is free, and it is the right call even if you are not sure how bad the injury is.
  4. Make the scene safe. Get uninjured people off the carriageway and behind something solid. On a fast road, this matters more than the vehicles do.
  5. Photograph everything before anything moves. Wide shots showing both vehicles in position relative to the road, then close-ups of damage, then plates, then the road itself — skid marks, debris, the junction, the signs.
  6. Call the police, or 1155. The Tourist Police line puts an English speaker on the phone, which changes the character of the next hour completely.
  7. Call your rental company or your insurer. They send the surveyor. On a hire vehicle this call is contractual — most agreements require it immediately.
  8. Wait. Do not agree anything, do not sign anything, do not hand money over, and do not let the vehicles be moved until the police or the surveyors have seen them, unless you are being told to move by an officer or the position is genuinely dangerous.
  9. Get seen at a hospital if there is any doubt at all, and keep every piece of paper you are given.

Have this ready before you need it. Save 1669 and 1155 into your phone on your first day, and screenshot your rental agreement and the rental company's emergency number. Our Thailand emergency numbers card is designed to be saved to a phone or printed and folded into a wallet, and the accident action plan is this page compressed to one screen.

Who to call, and what each number gets you

NumberWho answersCall it when
1669National emergency medical service, run by the National Institute for Emergency MedicineAnyone is injured. This is the ambulance number.
1155Tourist Police Bureau — English-speaking officers and volunteers, 24 hoursYou need a police officer who can talk to you, or an interpreter between you and the other driver.
1193Highway Police DivisionThe crash is on a highway rather than a town street.
1543Expressway Authority of Thailand, option 1, 24 hoursYou are on a Bangkok expressway. See breaking down on an expressway or motorway.
1586Department of Highways; press 7 for motorwaysYou are on an intercity motorway or need the highway authority.
191General police emergency line — universally published, though answered in ThaiNothing else is getting through. Expect to need Thai.

The honest ranking for a foreign driver is: 1669 for injuries, 1155 for everything else. 191 is the number every guidebook prints and it is genuinely the general emergency line, but it is answered in Thai — and a caller in shock describing a location in a language they do not speak is not in a good position. 1155 is the fastest route to someone who can translate.

Why you wait instead of exchanging details

At home, the aftermath of a minor collision is administrative: names, insurers, policy numbers, photographs, and a claim filed a week later. Thailand does it differently, and the difference is the surveyor.

Thai motor insurers keep claims staff on motorbikes and in small cars whose job is to attend accident scenes. Each insurer sends its own. They photograph the positions, take an account from each driver, talk to each other, and between them settle which vehicle was at fault and which policy pays. If a driver's own policy covers the damage, the surveyor issues a claim document at the scene that authorises repair at an approved garage. It is fast, it is normal, and for anyone with proper cover it is the point at which the accident stops being a problem.

Two things follow from that, and both are the reason you stay put:

The surveyor is worth understanding properly before you need one, and the insurance surveyor at a Thai accident scene explains who they work for, what they can and cannot decide, and how to handle one who is not yours. How fault is actually decided covers the rest of it.

What to photograph, in order

Your phone is the most useful thing you own for the next hour. Take far more than you think you need, and take it in this order, because if you are moved on you will at least have the important frames.

  1. Two or three wide shots from different angles showing both vehicles where they stopped, with the road, the lane markings and any junction visible.
  2. The other vehicle's registration plate, clearly readable.
  3. Damage to both vehicles, close up, from several angles.
  4. The road surface: skid marks, gravel, spilled fluid, debris, the pothole or sand patch if one was involved.
  5. Signs, signals and road markings that bear on who had priority.
  6. The other driver's licence and, if there is one, the compulsory insurance sticker on the windscreen.
  7. A short video panning across the whole scene, narrating what you can see. It records things you will not think to photograph.

Note the time and the exact location. Drop a pin in your maps app and screenshot it. Thai rural addresses are hard to give over the phone, and an ambulance or a surveyor asking "where are you?" is asking a genuinely difficult question. A pin you can read out — or send — solves it.

Injuries: what you can usefully do

Call 1669 first. Beyond that, keep to basics: do not move anyone who is unconscious or complaining of neck or back pain unless leaving them where they are is more dangerous than moving them; apply firm direct pressure to heavy bleeding with whatever clean cloth you have; keep an injured person still, shaded and talked to. Leave helmets on unless the person is not breathing. Anything more than that is for the paramedics, who are coming.

Ambulances in Thailand are dispatched through 1669 but delivered by a mix of hospital services and volunteer rescue foundations, so the vehicle that arrives may be a foundation's rather than a hospital's. That is normal and it is not a sign that something has gone wrong.

Grazes and burns from a scooter spill look trivial and are not, in this climate — road rash and exhaust burns explains why a wound that would scab over at home turns nasty here within a day or two. Thai hospitals after a crash and what it costs covers the government-versus-private question and how the deposit works.

The police report, and why you want one

A police report is the document that lets everything else happen. Insurers want it. Rental companies want it. Your travel insurer will ask for it. If you are claiming against another driver, it is the backbone of the claim.

In practice, either an officer attends the scene, or the drivers are asked to come to the local station to make statements and the report is written there. Officers may take some time to arrive, particularly outside cities and particularly if nobody is hurt. Waiting is still the right answer in most cases; should you call the police after a crash goes through the exceptions honestly, including the very small knocks where nobody sensibly involves them.

Never sign a document you cannot read. Statements are written in Thai. A signature on a Thai-language page you have had summarised by the other driver, a bystander or a rental agent is a signature on whatever it actually says. Ask for the Tourist Police, ask for an interpreter, and if in doubt say that you will sign once someone you trust has read it to you. Nobody can require you to sign on the spot.

If the vehicle is a hire car or a rented scooter

Ring the rental company before you ring anyone except the emergency services. Their insurer's surveyor is the one attending, their agreement almost certainly requires immediate notification, and letting a repair be arranged privately is the fastest way to a fight over the deposit. Accident in a rental car or scooter covers the sequence, the excess and what happens to the money you left with them. If the argument afterwards is about a charge rather than the crash, the Renting section is where the dispute side lives — start with disputing a rental charge.

If it is your own machine, or one you have borrowed from a friend or a guesthouse, there is no rental company to absorb any of this and the position is different again: see crashing a bike you own or borrowed.

Money at the roadside

You will sometimes be offered, or asked for, a cash settlement on the spot. It is a normal way of dealing with a scraped mirror between two locals. For a visitor it is riskier: you cannot verify what you are settling, you have no receipt that means anything, and the payment does not protect you if the other party later goes to the police. Settling a minor accident at the roadside sets out when it is reasonable. The short version: never on a vehicle that is not yours, never where anyone is injured, and never before the surveyor has been.

If it is serious

Where someone has been badly hurt or killed, the process changes character. Failing to stop and assist after a collision carries, on the pre-2022 text of the Act, up to three months' imprisonment and a fine of 2,000–10,000 baht, rising to up to six months and 5,000–20,000 baht where serious injury or death results. A driver may be detained while an investigating officer works, and alcohol or the absence of a valid licence transforms the position. What happens if you are arrested after a crash describes the process step by step — and says plainly that at that point you want your embassy and a Thai lawyer, not a website.

What the law says

Under the Land Traffic Act B.E. 2522 (1979), a driver involved in a collision causing damage or injury must stop, give assistance and identify themselves (s.78). Failing to do so is punished under s.160: up to three months' imprisonment and/or a fine of 2,000–10,000 baht, and up to six months and 5,000–20,000 baht where serious injury or death results. Section 140 excludes this offence from the fixed-penalty ticket system — it cannot be settled with a roadside fine. Thai penalties are maximums, and what a court actually imposes is a separate question.

The mistakes that cost the most

Before any of this happens

Most of what makes a Thai accident go badly for a visitor is decided in advance: the licence entitlement you hold, whether your travel policy covers the machine, whether you were wearing a helmet, and whether you have the numbers to hand. Does travel insurance cover driving in Thailand and what voids your motorbike cover are the two to read before you collect a bike; the biggest risk factors for visiting drivers and what the road-death statistics really say are the risk picture.

Frequently asked questions

Can I just exchange insurance details and leave, like at home?

No, and it is the most common and most expensive mistake foreign drivers make here. Thai claims are settled at the scene by surveyors from the two insurers, working from where the vehicles are and what the police record. Leaving means the account that survives is the other driver's, and it means the paperwork every party downstream will ask you for does not exist.

Which number do I actually call first?

1669 if anyone is hurt. 1155 if nobody is, because you get an English-speaking police officer. 191 is the general emergency number and is universally published, but it is answered in Thai.

How long will I be at the scene?

Longer than you want. A straightforward two-vehicle knock in a city might be dealt with in an hour or two once the surveyors arrive; a rural crash, or one where an officer has to travel, can take considerably longer. Get into the shade, drink something, and accept that the afternoon has gone.

The other driver wants to settle in cash and go. Should I?

Not on a rented vehicle, not where anyone is injured, and not before a surveyor has seen it. On genuinely trivial damage between two people who both understand what they are agreeing, it happens all the time — but you cannot verify what you are paying for, and it does not stop a complaint being made later.

Do I have to hand over my driving licence to the police?

You must be able to produce it, and a photocopy or a digital version is acceptable. Since September 2019 an officer has no power to confiscate a driving licence at the roadside. What Thai police can and cannot ask you for sets out the position.

What if the other rider has no insurance, or rides off?

Photograph the plate before anything else if you possibly can. Compulsory insurance attaches to the vehicle rather than the driver, so a registration number is what makes a claim possible at all. If the vehicle cannot be identified, your own travel policy becomes the whole of your protection — see if someone hits you in Thailand.

I was not hurt, so do I still need a hospital?

Get checked if you hit your head, if you lost consciousness even briefly, if you have any pain in your neck or back, or if you have grazes that broke the skin. Head injuries and tropical wound infections are the two things that turn a walk-away crash into a serious problem days later.
