Jeepneys are the most common form of public transport throughout the many islands of the Philippines. In Manila they are so numerous, that there is almost constantly traffic congestion. The jeepneys don't have air-conditioning. They have open windows. Most of the time the jeepneys are constantly-packed with many passengers. Jeepneys offer one of the cheapest ways of getting somewhere. They seldom have a special place to stop. The drivers will slow down enough to enable the passengers to jump on or out.
