I have to admit I have never had a Thai driving license in all my years here, I really cant see the point, if they want money out of you on the toll ways the police will get it, so why even bother?
I just carry a couple of 10 year old or more international driving licences and hand them over, woh haa they say when they see they are out of date, but then I ask them why should I carry a current one, I have had loads of them confiscated, why should I give a fok, they are out of date and useless, police stations all round Thailand have my old licenses, I aint gonna pay them, the last cnut I spoke to said I was doing 120km per hour, it was like a foking traffic jam for 5 km and I didn't get over 60km per hour, dont even bother with a license I reckon.
