Medical certificate for a Thai driving licence (2026): what's checked, documents and cost

Which certificate is required

The Department of Land Transport requires the certificate approved by the Thai Medical Council. It has two parts: the applicant's own health declaration, and the doctor's examination and opinion. The doctor must certify that you have none of the five prohibited diseases under the ministerial regulation and no disease or condition that would impair driving.

Watch the document's age: it must have been issued no more than 1 month before the day you apply. If you get examined too far in advance you will need a new one, so fix your transport-office date first, then come for the examination.

What the doctor checks

• History of conditions that affect driving, such as epilepsy, uncontrolled heart disease, diabetes with frequent low blood sugar, or eye disease
• Blood pressure, pulse, weight and height
• A general physical examination, checking for signs of the five prohibited diseases
• The doctor's opinion on the form with their name, licence number and the clinic's stamp

Good to know: A standard driving-licence certificate needs no blood test and no fasting. Colour-vision, eyesight and reaction tests are done at the transport office, not as part of the certificate.

Documents for the transport office

For renewing a private licence the main documents are your original ID card (or passport with a valid visa and work permit or residence certificate for foreign nationals), your current licence and a medical certificate under 1 month old. Renewing a 5-year licence to another 5 years requires training, now available in advance through the DLT e-Learning system, plus physical tests at the office.

Training, booking and testing rules change with DLT announcements, so check the DLT website or the DLT Smart Queue app before you go. What the clinic can guarantee is the right certificate, issued in time.

Can a local clinic issue it?

Yes. A medical clinic with a licensed doctor can issue the Medical Council certificate just like a hospital. Mongkhondee Clinic at Pantip Bangkapi is open every day, until 8 pm on weekdays, so you can drop in after work. The cost is 200 baht. See the medical certificate service page for details.

If you are unsure whether a condition of yours might count as impairing driving, bring your medication and treatment records. The doctor will assess and explain before issuing the document.

Public-transport and commercial licences

Public-vehicle licences such as taxi, and commercial driver licences under transport law, have extra conditions such as a criminal record check and in some cases a drug-test result, and individual transport offices may set different details. Ask your transport office exactly what it needs, then send us the list so we can check what can be done at the clinic.
