Folks. Please remember it is up to the police officer that pulls you over. If you just arrived then you can probably use for 2 months. However, after 2 months you will need a Thai license. Again, every province has different rules or interpret the law differently. I have Canadian bike with IDP and have been charged in CNX. 500 bahts if they actually write you a ticket. 1000 if they strong arm you. Fact is when they take your keys you are at their mercy. I would suggest to anyone just go get a Thai one. Very easy. But like I said every province seems to make up their own rules. And for 200 Bahts it costs the keys stay me and I ride away.
