Two foreigners walk into a Bangkok DLT office. One walks out in 90 minutes. The other needs two separate visits, a written exam, and a driving test. The difference: whether they already hold a valid license from home. This guide breaks down exactly which path applies to you, and why the gap between them matters.
| Converting an existing license | Acquiring from scratch | |
|---|---|---|
| Who it's for | You hold a valid license from your home country | You don't have a foreign license, or yours isn't eligible |
| Eye and reaction tests | Yes, mandatory for every applicant | Yes, mandatory for every applicant |
| Written exam required | No | Yes |
| Practical driving test required | No | Yes |
| Typical visit time | About 1.5 hours | A couple of DLT visits |
| License issued | Temporary 2-year license, upgradable to 5 years | Temporary 2-year license, upgradable to 5 years |
| Core documents | Passport, visa, Residence Certificate, TM30, medical certificate, existing license | Passport, visa, Residence Certificate, medical certificate |
Why conversion is faster
Thailand's DLT recognizes driving experience you've already demonstrated to another country's licensing authority. Converting swaps the theory and practical exams for a document check: your foreign license, valid for at least 6 months, stands in for them. The eye and reaction tests still apply to every applicant, but they take a few minutes. That is why a conversion takes 1.5 hours while a from-scratch application takes multiple visits.

Why some people still need to start from scratch
Not everyone qualifies for conversion. Three common situations force the from-scratch route:
- No foreign license at all. If you've never held a driver's license anywhere, there's nothing to convert.
- A license type the DLT doesn't recognize for conversion. A handful of countries and license categories fall outside the standard conversion list. The DLT confirms this at submission, not before.
- An expired or soon-to-expire foreign license. Conversion requires at least 6 months of remaining validity on the original license.

The hybrid option most people don't know about
If you're converting one license type and need the other from scratch, for example converting a foreign car license while acquiring a Thai motorbike license for the first time, you don't need to run both processes at full price. Since you're already converting a license, the motorbike side can skip its usual 5-hour beginner class and go straight to the theory and practical exam.
Which path costs less?
Conversion is consistently cheaper than acquiring from scratch, since it skips the theory exam, the practical exam, and the beginner class. Exact fees depend on whether you're doing a motorbike, a car, or both together. Fatboy's Services publishes current pricing directly on each license service page.
How to check which path applies to you before you go
- Check whether your home country's license is on Thailand's conversion-eligible list. If you're unsure, message a local service or ask directly at the DLT.
- Confirm your license has at least 6 months of validity remaining.
- Confirm your visa category qualifies. Tourist visas don't qualify for either path.
- If converting, gather your documents in advance. Missing paperwork is the most common reason for a wasted DLT trip.
