The police are out in force now, breath testing for drinking and driving/riding. Obviously their preferred prey are farangs on motorbikes but the 6/7 times I saw them they breath tested everything and anything. They've set up various semi-permanent checkpoints around Pattaya. The fine is 10000 baht (so I'm told) so if you're drinking I suggest you don't drive or ride. I was tested 4 times and the other 3 they recognised me and just waved me on.
