tuk tuk
A tuk-tuk is a three-wheeled taxi that is popular in Thailand.
The most popular theory is that the name derives from the sound it makes when traveling.
Tuk-tuks have license plates, and you cannot drive a tuk-tuk with a motorcycle or four-wheel vehicle driver's license.
Also.
By law, only Thai nationals are allowed to operate taxis, so tuk-tuk licenses are only granted to Thai nationals.
Tuk-tuks currently exist mainly in large cities such as Bangkok as a means of transportation for sightseeing, but they
are usually more expensive than taxis when tourists try to use them.
