Can my friend get a Thai driver's license without taking a test if they didn't get an International Driving Permit?

A U.S. driver's license holder without an International Driving Permit (IDP) may still obtain a Thai driver's license, but requirements vary by local Department of Land Transport (DLT). Many DLT offices require an IDP to avoid a driving test. Without an IDP, the individual may need to complete a video test beforehand, which generates a QR code. Some sources suggest it's quicker and easier to take the driving test instead of dealing with the IDP application process. It is also noted that some people have successfully obtained a Thai driver's license with minimal testing when presenting their U.S. license.
