@Lloyd ********
I don't know what I have said that is wrong, that you needed to 'correct' me on. I didn't provide any specific information, rather, suggesting that the OP provide more information, so that others can be specific in their advice. That's why the two questions at the beginning of my comment. I'm fully aware that if one has a Thai Driver's License, they don't need an IDP. from personal experience, I know that an IDP is for people who are visiting another country, short term, who wish to drive themselves around while in foreign countries.
