I live in Phuket. Fines have defintely skyrocketed in price , Im told no IDP/Thai license is now 1-2000 bt , no helmet 500-1000 with receipt. These were once 300bt and are the real earners , its rare to see Police chase down the puffed up meat heads and north Africans screaming thru the villiages. Having said that , I live in Kamala wherein , due to the efforts of one very honest snr cop , proper policing often takes place. The local police are pleasant and politely direct. Pity they arent about at 5pm high season....my experiences in Kamala.. 18 years ago I went DUI , "fine" was 20k no receipt , paid 17k. One time was stopped at roadblock , no helmet , 300 with receipt. Ran an orange and was chased down recently , apologised , license showed local address , let go. Im rarely stopped at roadblocks , but Chalong is the only place I know has a very bad reputation and anything can happen.
