The auto rickshaw, called tuk-tuk (Thai: ตุ๊ก ๆ) in Thailand, is a widely used form of urban transport in Bangkok and other Thai cities. The name is onomatopoeic, mimicking the sound of a small (often two-cycle) engine. An equivalent English term would be “putt-putt”. It is particularly popular where traffic congestion is a major problem, such as in Bangkok and Nakhon Ratchasima. Drivers may also use their tuk-tuks to transport fresh produce or other goods around the city in absence of passengers.
Bangkok and other cities in Thailand have many tuk-tuks which are a more open variation on the Indian auto rickshaw. About 20,000 tuk-tuks are registered as taxis in Thailand. Bangkok alone is reported to have 9,000 tuk-tuks.
