How to get your Thailand drivers License
Using your current drivers license to receive a Thai drivers license is quite an easy process that anybody should be able to do. It is best to arrive early as it may take a couple hours due to a long queue.
Go to the nearest Department of Land Transport Office where they process all of Thailand's driving licenses. There you will be able to receive any forms required and the information desk can generally help you fill them out. Bangkok's main offices are next to Mo Chit BTS station and Bang Chak BTS station. To view in Google Maps click Mo Chit or Bang Chak.
The general required documents to bring with you are as listed below. Also, be sure to bring copies.
Your Passport with valid non-immigrant visa. (a tourist visa is not accepted)
Your Work Permit or Certificate of Residence issued by your embassy or Thai Immigration Bureau not more than 30 days old
