The Tuk-tuk (Thai: ตุ๊กตุ๊ก Tuk-tuk; English: Motor tricycle) is the Thai nickname given to an auto-rickshaw, a three-wheeled miniature truck. Tuk-tuks are popular in South and Southeast Asia as they provide a cheap and small transport vehicle to be used for taxiing services or for transporting commercial goods.
"This auto rickshaw is not recommended for military service or any other heavy duty job. It will take you to your destination though - very cheap, special price."
— In-game description
In Battlefield: Bad Company 2: Vietnam, the Tuk-tuk is a light vehicle that appears exclusively in Conquest mode, and spawns regardless of which faction controls the nearby flag. It has space for three players: one driver and two passengers, one crouched and facing backwards, the other standing and peeking over the driver's hood. It drives at a moderate speed and has very little torque, meaning it has slow acceleration and cannot climb steep inclines. It's not recommended to drive it around where combat is going on, since a couple of shots from a conventional weapon, or a sudden explosion, could already destroy it. Additionally, driving into a tree or another obstacle on its full speed causes it to detonate as well.
