No they said since I had a US DL and Motorcycle license I just did a reaction test, call out the lit three colors on a traffic light and a depth perception. Really easy. I also had to get another resident letter from the immigration office and doctor filed out a paper (physical 5 minutes) plus copies of everything. They had a copy place on site. So fee I believe under 400 baht, physical 80 baht. But I hear some places are different.
good info exactly how my purchase went. The dealer was great, he even took me to the adjacent office where they do drivers licenses. Where I got all the info and was smooth to obtain.
I have been in Thailand over two years. Show em a photo of your med and they will sell it! If they don’t have the exact named med they will find a generic or comparable med.
