The night I got pulled over at a checkpoint on Rama IV
January 2019, 11:30 pm, heading home from dinner in Thonglor. Police checkpoint on Rama IV, right before the Silom intersection. The officer waved me down, I rolled down the window, and there it was: "License, please." I handed him my French permit. He looked at it, flipped it over, frowned. "International?" I didn't have one. He pulled out his receipt book. ฿500 fine. Cash. On the spot.
That night I learned two things. First, a French license on its own means absolutely nothing in Thailand — no matter what everyone at your local bar tells you. Second, if you're in an accident, your insurance can flat-out refuse to cover anything if you don't hold a locally valid license. And that's a whole different level of problem than ฿500.
I got my license converted three weeks later. The process is surprisingly straightforward. But there are details that can cost you half a day if you show up unprepared. Here's everything I've learned.
French license, international permit, Thai license: what's actually valid?
There's endless confusion among expats on this topic. Let me set the record straight.
| Document | Legal validity in Thailand | Accepted by insurers | Validity period |
|---|---|---|---|
| French license alone | Not recognized | No | — |
| International Driving Permit (1949 Geneva Convention) | Yes, for tourists (90 days max) | Generally yes, within the 90-day limit | 3 years (but limited to length of stay) |
| Temporary Thai license | Yes | Yes | 2 years |
| 5-year Thai license | Yes | Yes | 5 years |
The French international driving permit — the one you get for free at the préfecture or through the ANTS website — is essentially an official translation of your license. Thailand recognizes the 1949 Geneva Convention, so it's technically valid for temporary stays. But if you actually live here — Non-Immigrant visa, retirement visa, work visa — it's no longer enough. You need the Thai license.
Key point: In a serious accident, it's the Thai license that protects you. A friend of mine had a fender-bender in Chiang Mai with only his international permit while he was residing in Thailand on a work permit. His car insurance covered the vehicle damage, but his health insurer initially disputed covering his medical bills. He eventually won, but it took four months of back-and-forth. Don't take that risk.
Documents to prepare (and the one everyone forgets)
The conversion is handled at the Department of Land Transport — the famous DLT. In Bangkok, I did mine at the Chatuchak office (Mo Chit), but the Bangkapi branch works too. Here's the exact checklist:
- Original passport + photocopy of the ID page and the page showing your current visa
- Original French driving license + photocopy
- Certificate of residence issued by the French Embassy in Bangkok (or the relevant consulate)
- Medical certificate (ใบรับรองแพทย์) dated less than one month prior
- Certified translation of your French license — and this is the one so many people forget
- ID photos (usually taken on-site at the DLT, but bring two just in case)
The certificate of residence is obtained from the French Embassy, 35 Charoen Krung Soi 36. You need to book online, and bring proof of address in Thailand — a lease agreement, an electricity bill in your name, or a letter from your landlord. It costs ฿380 and takes a few days. Some people get it the same day; others have to come back.
The certified translation of your license is the classic trap. Your permit is in French; the DLT can't read it. Two options: have it done by the French Embassy (they offer this service) or by a recognized sworn translator. The Embassy is the safest bet because the DLT always accepts their documents without question.
The medical certificate is the easiest part. Any clinic in Thailand can do it. Walk in, say "medical certificate for driver's license," pay between ฿100 and ฿200, the doctor checks your blood pressure and eyesight, and signs off on the form in five minutes. Look for a clinic that uses the standard DLT form.
Practical tip: Make all your photocopies BEFORE heading to the DLT. There's a little copy shop right across from the Chatuchak office, but the queue there can be long and you'll lose your spot in the main line. Sign each photocopy in blue pen with "certified true copy" and the date. The officers ask for this every single time.
D-Day at the DLT: how it actually goes
Get there early. I'm not saying that for dramatic effect. The Chatuchak DLT opens at 8:00 am, and the queue numbers start being handed out at 8:00 sharp. I showed up at 7:40, got number 12. I was out before noon. A colleague who arrived at 10:00 didn't leave until 3:30 pm.
The process unfolds in several steps:
- Document check at the reception counter. The officer goes through your file and makes sure everything's there. If a single paper is missing, it's game over — come back another day. No negotiating.
- Basic physical tests. This is where people panic for no reason. It's a color perception test (they show you traffic lights — red, green, yellow — you say the color), a reflex test (you press a pedal when a light turns red), and a peripheral vision test. Nothing complicated. I've never seen anyone fail.
- Road safety video lasting about an hour. In Thai, sometimes with English subtitles. It's the longest and most tedious part. But it's mandatory. You get a certificate of attendance at the end.
- Photo and license production. You pay ฿205, they take your photo, and your laminated license comes out a few minutes later.
No written test. No driving test. That's the whole point of a conversion: France and Thailand have an agreement that mutually recognizes each other's licenses. You prove you hold a valid French license, and the DLT issues you a Thai one.
Temporary 2-year license, then the 5-year: what comes next
The first Thai license you get through conversion is a 2-year temporary permit. That's completely normal — it's the same for everyone, including Thais getting their license for the first time.
Before those 2 years are up — ideally within the 90 days before the expiration date — you go back to the DLT to renew. This time, you get a 5-year license. The paperwork is lighter: passport, your old Thai license, a recent medical certificate, and ฿505. The whole thing usually takes under two hours.
I'm currently on my second 5-year license. Each renewal has been faster than the last. The DLT has genuinely improved its processes in recent years, notably with a digital queue system.
Mistakes that waste your time (or worse)
Over seven years, I've helped plenty of friends and acquaintances through this process. Here are the mistakes I see come up again and again:
Showing up without a certificate of residence. This is by far the number-one mistake. People assume a utility bill or lease will do. It won't. The DLT wants the official document from the embassy or, failing that, a letter from immigration (if your visa type allows it). Get this sorted in advance.
Showing up with an expired French license. Sounds obvious, but I've seen it happen twice. Your French license must be currently valid at the time of application. If you haven't renewed it from France (which you can do online through the ANTS website), the DLT will refuse you.
Forgetting that the motorcycle license is separate. In France, a category B license lets you ride a 125cc scooter after a short training course. In Thailand, the car license and motorcycle license are two completely separate documents. If you want both, you need to submit two applications. A French motorcycle license (category A) converts through the same process as the car license.
Thinking your Thai license works for renting abroad. A bonus tip for those who travel around the region: a Thai license is not an international document. To rent a car in Cambodia, Laos, or Malaysia, you need a Thai international driving permit — which the DLT also issues, for ฿205. But that's a topic for another day.
What I wish I'd known from the start
If I had to boil down seven years of dealing with this paperwork into a few lines, here's what I'd say.
Do it as soon as you settle in. Don't put it off. Every month without a Thai license is a month you're driving with no safety net if something goes wrong. And accidents in Bangkok aren't a question of "if" — they're a question of "when."
The whole process, including the embassy appointment for the certificate of residence, the clinic visit, and the trip to the DLT, takes about a week if you stay organized. Total cost runs between ฿1,200 and ฿1,500 all in — certificate of residence, medical certificate, translation, DLT fees. That's a trivial amount for the peace of mind it buys you.
And above all: don't listen to the people who tell you "it's fine with just the French license." It's fine, until the day it isn't. And on that day, you'll be glad you've got a little pink-and-blue laminated rectangle with your photo and Thai characters you can't read — but that actually protects you.
