The maximum fine for riding a motorcycle without a helmet in Thailand is 2,000 baht for both the driver and passenger. All these photographs and many more were taken during two hours one afternoon on Sukhumvit, a 6/7-lane dual-carriageway road.

This sums it up very well.

I’ve been a passenger without the helmet on motor cycle taxis many times. Silly I know.

As I recall motorcycles aren’t slowed on the actual freeways? (I know Sukhumvit isn’t a freeway.)
