If you’re applying for a Thai driving license, or renewing an existing one, you’ll need more than just the theory and practical driving tests. One essential document is the medical certificate (ใบรับรองแพทย์), which confirms that you are physically and mentally fit to drive. This guide explains everything you need to know before your appointment at the Department of Land Transport (DLT).
What is the medical certificate for a Thai driving licence?
The medical certificate is an official document issued by a licensed doctor in Thailand. It confirms that you do not have any conditions that may interfere with safe driving and that you are fit both physically and mentally. The medical certificate is valid for 30 days from the date it is issued.
This certificate is required when:
- Applying for your first Thai driving licence
- Renewing an expiring licence
- Changing licence types
- Applying for a public or commercial driving licence
This requirement has been enforced since 19 February 2021 and is mandatory at all DLT offices nationwide.
What medical checks are included?
The medical certificate for a driving license involves screening based on DLT requirements. These checks may differ slightly from a standard medical certificate for work.
The examination typically includes:
- Vision test (including colour vision, depth perception, and distance vision)
- Blood pressure, pulse, weight, and height
- General physical and mental health evaluation
- Hearing test
Fasting is not required prior to the health check. You may obtain the medical certificate from any clinic or hospital across any province. Just ensure that the facility uses the official DLT medical certificate form.
Tip: To avoid having to repeat the health check, it’s best to get the medical certificate close to your appointment date at the Department of Land Transport. It also includes screening for certain serious medical conditions that may prohibit the issuance or renewal of a driving licence, such as:
Conditions that may prevent you from getting a driving license
The Department of Land Transport (DLT) has outlined specific medical conditions that disqualify individuals from obtaining a driver’s license. These include elephantiasis, tuberculosis (in its contagious stage), leprosy, chronic alcoholism, and drug addiction.
In addition to these, there are several health conditions considered high-risk for driving. These do not automatically disqualify a person but may require further medical assessment. Such conditions include epilepsy, certain eye diseases, neurological disorders, heart disease, uncontrolled diabetes, stroke, Parkinson’s disease, arthritis, osteoarthritis, and the use of medications that cause drowsiness.
If you have any of these conditions, discuss your situation with a doctor before applying.
Where to get the medical certificate & typical costs
You can request the certificate at any clinic or hospital in Thailand. What differs is speed, language support, and price.
- Local clinics are usually the quickest and cheapest. Staff are used to walk-ins requesting driving license certificates. Expect around THB 50–100.
- Public hospitals are more standardised but slower. Expect THB 200–300.
- Private hospitals provide the most comfortable experience and better English communication, but are typically more expensive, especially if extra tests are included. Prices often start around THB 1,400.
A useful tip: Clinics located near DLT offices do this paperwork every day. They know the exact form required and can prepare it quickly. Even if English is limited, communication tends to be straightforward because the purpose is familiar.
Final thoughts
The medical certificate ensures that every driver has the physical awareness and mental readiness to handle real-world conditions on the road. And in Thailand, where road environments can vary rapidly, that readiness matters.
Even with experience and caution, accidents can still happen. That’s why having the right insurance is just as important as having the right license.
