I've been stopped by a end-of-month police traps in Bangkok twice over the last few months, for some imaginary offences. The first time they impounded my Thai licence (just like they did with all the other Thai drivers that were caught along with me), and even though I went to police station to explain and negotiate, they refused to returned my licence unless I paid the fine (which I, sadly, did). I asked around, including at the Canadian Embassy, and I was told that Thai Police is NOT allowed to keep you licence - they can copy the information from it, issue you a ticket, possibly take you to court if not payed, but can't keep the licence for ransom. When I was stopped the second time, I showed the licence to a cop, but refused to give it to him (kind of wrestled it out of his hands...). We went to a station, and the negotiation was much easier this time. So my question is this: is there a written law or a document that one can use to explain the above to the police i.e. that they are not allowed keep my driver's licence when they stop me, and if so, where to find it? I"m afraid that the next time I'm stopped, they will ask me for a licence, which then will be taken away as a bargaining chip. Cheers!
