Newly settled in Bangkok, I’m told that I can show my Califonia Drivers License at the DLT and they accept it for granting a Thai Drivers License/ID Card. What other docs, paperwork or other requirements besides Passport must be in-hand before showing up to apply for a Thai Dr. License?
TLDR : Answer Summary
To apply for a Thai driver's license in Bangkok, in addition to your passport, you will need the following documents: a California driver’s license (which may be accepted), a residence certificate from immigration, a medical certificate from a doctor, and possibly an International Driving Permit (IDP). You should also be prepared to complete vision and reaction tests at the Department of Land Transport (DLT). In general, having a Thai driver's license can facilitate various local transactions and services, even if you do not plan on driving.
