you don't even have to do the written test. With an IDP or English language driver's license : only do the reaction tests. Really easy.
1. Get medical certificate for 100-200b
2. Get Certificate of Residence from immigration (valid 30days)
3. Go to your local DLT with you American driver's licence.
4. Pass reaction test.
5. Take a picture and pay 205b
6. Walk out with your Thai licence
