Also, it's not an "international driver's license". That's a misnomer. It's an "international driver's permit" (aka "IDP") and it augments one's license from their home country. My question was whether one needed a motorcycle endorsement (also casually referred to as a license in casual speech, but actually something that augments one's driver's license) from their home country in order to drive in motor bike in Thailand. This is unrelated to the need for an IDP which is, of course, necessary if using a foreign license. This would be necessary if Thailand has separate licensing for motor bikes. THAT was my question.
Meanwhile, my question was not about driving in Thailand. It was about obtaining a license. While driving in Thailand requires one to have an IDP, TECHNICALLY, according to the Thai embassy, one does not need an IDP to obtain a Thai license IF the home country's license is in English OR if one obtains a translation from their embassy. However, I don't know why someone would go to Thailand and not drive until they could obtain a license when bringing an IDP is so simple...I suppose it's possible.
