not only is it actually written on the permit itself (Page 2 inside front cover, second paragraph) but under Thai law only aliens without a non immigrant visa may exercise their treaty rights by driving on a home licence in conjunction with an IDP.
I think this is badly written. You have never been able to just use an IDP to obtain a temporary license it has always required physically presenting your home country license.
nope, it’s valid until it or your home country license expires. There is no 90 day law. As long as your not on a Non Immigrant visa and are a tourist then the IDP is good until it expires. Always stand to be corrected, can you give me a legal source for the 90 day limit?
incorrect, it is valid until it expires. There is no law regarding 90 days usage. As long as you are not on a Non Immigrant visa then the IDP is valid until it or your home country license expires. I stand to be corrected if you can state the relevant law.
there is no such animal as an international driving licence. It is an international driving permit that legalises your home country driving licence under the convention. Thailand accepts and will continue to accept IDPs.
