How to behave with Thai policeman

The best way is to smile, listen and fulfill instructions. Never raise up the voice, it’s totally impolite in Thailand and the easiest way to show policeman that you are inadequate. If police stop you in the nighttime it can be just simple alcohol check. If you had really disobeyed the rules policeman will explain you the reason he stopped you and write out a fine bill. No one would take out your passport or driving license except the case you actions leaded to the accident. You can simply pay standard penalty 600 baht right on a place.
