It's working and now I read that that this Helmet law will be throughout the whole of Phuket on the 1st of January !
I have read a lot about this (and written here) and from as a cyclist there are a lot more people wearing motorbike helmets - were these two riders fined?
I haven't see this machine again.
But just in case you have forgotten these are the fines.
500 Baht for not wearing a helmet.
If the passenger is not wearing a helmet the driver pays an additional 1,000 Baht!
