This site is about the Sam Laws (three wheels in Thai). These are seen and still used throughout Thailand as a major for of transportation in citys and towns with the exception of Bangkok. Most were made in the 60's-70's and are still on the road. To my knowlege they are no longer produced.
I have 6 of these vehicles that I'm currently restoring and will soon be offered for sale.
Check out my photography web site at: www.ultraluminousgraphic.com under; Projects, SamLaw Life for more photos of the freewheeling bunch of guys that are the Sam Law drivers of Thailand.
