Now in the old days you may have been driving around in Pattaya on your untaxed and uninsured motorbike, whilst drunk, without a crash helmet and get caught jumping a red light at night with your lights off, the odds were you would get a ticket for no crash helmet, maybe a 200baht fine, but things are changing.
It seems now they are doing several of the charges to get the money in so to speak, most fines are around 500baht or more which is 2 to 3 days wages for your average Thai so quite a big hit, but they are now doing multiple charges.
My son got caught a couple of nights ago, no id, no crash helmet, no driving license, this was whilst jumping a red light, they ticketed him a 1,200baht fine for that little lot, not many 18 year old students can afford that sort of money, probably 2 weeks wages for your average 18 year old, expect juvenile crime to rise to help pay off their fines I think.
