A Thai driving licence medical certificate confirms you are fit to drive. It requires a short clinic appointment covering blood pressure, basic vision, and a medical history review. The certificate is valid for 30 days and must be signed, stamped, and issued by a licensed doctor on the correct DLT-recognised form. At Takecare Clinic Phuket, you can walk in without an appointment and leave with your certificate the same day.
A lot of expats confirm their DLT appointment in Chalong first and sort the medical certificate second. That is the wrong order. I see the fallout regularly: someone living in Rawai or Kata, licence renewal overdue, a DLT slot already locked in, and then a scramble to find an English-speaking doctor who can issue the right form before the appointment. Sometimes the certificate arrives late. Sometimes it comes back rejected at the counter because it is on the wrong form entirely.
The exam itself is not complicated. There are no blood tests, no fasting, and nothing you need to prepare for days in advance. What matters is knowing what the certificate must contain, what the DLT checks separately on the day, and how to time it correctly. This article covers all of that specifically for Phuket.
Who Needs a Driving Licence Medical Certificate
Every applicant needs one. First-time applicants for a Thai licence, people renewing an existing Thai licence, and foreigners converting a foreign licence at the Phuket DLT in Chalong all fall under the same requirement. This applies to both car and motorcycle licences.
There is no exemption for expats who have held a Thai licence for years. Each renewal requires a fresh certificate, not a copy of a previous one. If your licence has already expired, the process is the same: get the certificate first, then go to the DLT.
The Five Disqualifying Conditions — and What Does Not Automatically Disqualify You
Thai law lists five conditions that disqualify an applicant outright: mental disability affecting judgment, chronic alcoholism or drug addiction, leprosy in its contagious stage, tuberculosis in its contagious stage, and elephantiasis in its symptomatic stage. If you have any of these, a certificate cannot be issued.
Everything else is an assessment, not an automatic ban. Controlled hypertension, treated type 2 diabetes, mild asthma, managed epilepsy on medication: none of these automatically disqualify you. The doctor is looking at whether your condition, as it stands today, affects your ability to drive safely. Bring a list of your current medications and be straight with me about your history. An honest conversation at the clinic is far better than a problem at the DLT counter.
What the Doctor Actually Does at the Clinic
The appointment is short. Most patients are done in fifteen to twenty minutes. There are no blood draws, no lab results to wait for, and no fasting required.
When you arrive at Takecare Clinic Phuket, the doctor checks your blood pressure and records the result. A basic vision screening follows: you need to read a standard chart at the required distance, with glasses or contact lenses on if you use them when driving. The doctor then reviews your medical history, focusing on anything that could affect driving safety. If everything is in order, the certificate is signed, stamped with the clinic seal, and includes the doctor’s licence number.
The certificate must show your full name exactly as it appears in your passport. It must carry the original doctor’s signature, not a printed one, the clinic’s official stamp, and the doctor’s medical licence number. The DLT counter staff check all of these. One missing element means the document is rejected.
The DLT’s Own Tests — Separate From the Clinic Exam
This is the part most people miss. The clinic certificate and the DLT’s in-house tests are two completely separate requirements. Passing the clinic exam does not mean you are finished.
On the day of your DLT appointment in Chalong, the office runs its own physical tests. These include a colour identification check for red, green, yellow, and amber, a reaction time test using a foot pedal, and a depth perception test. These happen at the DLT, not at the clinic. You need to pass both.
Common Mistakes That Get Driving Licence Medical Certificates Rejected
The most common rejection reason I hear about is the wrong form. Not every clinic in Phuket uses the DLT-recognised certificate format. A letter on clinic letterhead, a standard health certificate, or a hospital discharge summary will not be accepted, even if a licensed doctor signed it.
The second most common problem is the 30-day validity window. The certificate expires exactly 30 days from the issue date. Get it one to three days before your DLT appointment. Getting it three weeks early and then having the appointment rescheduled is a genuine risk. The name on the certificate must also match your passport exactly. Bring the original: the DLT does not accept photocopies.
What If You Have a Chronic Condition?
You can still apply. Most managed conditions do not prevent a doctor from issuing the certificate. The key word is managed. Controlled blood pressure, stable diabetes, well-managed epilepsy with no recent seizures: these are conditions we can discuss and document clearly at the clinic.
Bring your medication list and, if you have one, a recent letter from your specialist. Be straightforward about your history. I cannot issue a certificate if a condition genuinely poses a driving safety risk, but most patients with common chronic conditions come through this process without difficulty. If you are uncertain, come in and we will talk through your situation before the exam.
Driving Licence Medical in Phuket — Timing Your Certificate for the DLT
The DLT office serving most of Phuket is in Chalong, on Chao Fa West Road. It is open Monday to Friday and closed on public holidays. If you are coming from Patong, Kata, Karon, or anywhere on the west coast, factor in the drive south.
Get your medical certificate from Takecare Clinic Phuket the morning before your DLT appointment, or the morning of. Both work well. Since no appointment is needed at the clinic, you do not need to schedule around anything. Walk in, complete the exam, and head to Chalong the same day or the next. That is the timing that works for most patients I see going through this.
2026 Update — Digital Certificates and What Has Changed
From June 2026, the Thai DLT began piloting acceptance of electronic medical certificates for licence renewals. The pilot currently applies to drivers under 55 applying for renewal, not first-time applicants or licence conversions. At this stage, Takecare Clinic Phuket issues stamped physical certificates, which are accepted at all DLT offices including Chalong. If the digital option becomes available more broadly, this information will be updated. For now, bring the original paper certificate to your DLT appointment.
Need a driving licence medical certificate in Phuket? Takecare Clinic Phuket is a walk-in clinic in Patong, open daily with no appointment needed. Our English-speaking physician issues the correct DLT-recognised certificate the same day. We see patients from across the island: Kata, Karon, Rawai, Chalong, Kamala, Bang Tao, and beyond. Bring your passport and your glasses if you wear them for driving. That is all you need.
How long does the driving licence medical take at a clinic in Phuket?
Most patients finish in fifteen to twenty minutes from walking in. There are no blood tests, no fasting, and no lab wait times. At Takecare Clinic Phuket, you register, see the doctor, and leave with a signed and stamped certificate the same day.
Can I get a Thai driving licence medical if I have high blood pressure, diabetes, or another ongoing condition?
In most cases, yes. The five conditions that automatically disqualify an applicant are very specific under Thai law. For other chronic conditions, the doctor assesses whether your health as it stands today affects your ability to drive safely. Bring your medication list and discuss your situation openly at the clinic.
Is the clinic medical the same as the tests at the Phuket DLT office in Chalong?
No, they are completely separate. The clinic certificate confirms your general medical fitness to drive. The DLT office in Chalong then runs its own tests on the day: colour recognition, a reaction time check, and depth perception. You need to clear both to proceed.
How close to my DLT appointment should I get the medical certificate?
One to three days before is the safest window. The certificate is valid for exactly 30 days and will be rejected if even one day over. Since Takecare Clinic Phuket is open daily with no appointment needed, getting it the morning of your DLT visit is a straightforward option for most patients.
What documents do I need for a driving licence medical in Phuket?
Bring your original passport and a photocopy of the photo page. Wear your glasses or contact lenses if you use them when driving, as the vision check is part of the exam. No blood tests, no fasting, and no prior appointment is needed at Takecare Clinic Phuket.
I live in Rawai and my DLT appointment in Chalong is tomorrow. Can I get the certificate today?
Yes. Walk into Takecare Clinic Phuket in Patong any day without an appointment. The driving licence medical exam takes around fifteen minutes and you leave with the certificate the same visit. Getting it today for a Chalong appointment tomorrow is one of the most common ways patients time this.
