Transport within Lao towns and cities is by two types of motorized samlaw (literally, "three wheels", more commonly known as jumbos and tuk-tuks , which function as share taxis for four or five passengers. Jumbos are the original Lao vehicle, a homemade three-wheeler consisting of a two-wheeled carriage soldered to the front half of a motorcycle. Tuk-tuks are really just bigger, sturdier jumbos, and Lao tend to refer to these vehicles interchangeably. To catch one, flag it down as it passes, tell the driver where you're going, and pay at the end of the ride. Payment is per person according to the distance travelled and your bargaining skills. Rates vary, but figure on around 500K per kilometre. In some towns, tuk-tuks run set routes to the surrounding villages and leave from a stand, usually near the market, once full.
