The dolmuş (or Minibüs as called in Istanbul) is a small bus (sometimes car) that will ride near-fixed routes. The ride may be from the periphery of a major city to the centre or within a city, but may also take three to four hours from one city to the next, when the route is not commercial for large busses. They sometimes make a detour to bring some old folks home or collect some extra heavy luggage. You will find them in cities as well as in inter-city traffic. The name derives from “dolmak”, the verb for “to fill”, as they used not to start the journey without a decent number of passengers. They usually leave when they are full, but sometimes start at fixed hours, whatever the number. All during their journey people will get in and out (shout “Inecek var” – “someone to get off” – to have it stop if you’re in).
The driver tends to be named “kaptan” (captain), and some behave accordingly. The fare is collected all through the ride. In some by a specially appointed passenger who will get a reduction, in others by a steward, who may get off halfway down the journey, to pick up a dolmuş of the same company heading back, and mostly by the driver himself. If the driver collects himself, people hand money on from the back rows to the front, getting change back by the same route. On some stretches tickets are sold in advance, and things can get complicated if some of the passengers bought a ticket and others just sat inside waiting – for maybe half an hour - but without a ticket.
The concept of dolmuş in Istanbul is somehow different than the rest of Turkey. The vehicles are different, they do not take any standing passengers, they do not tend to take passengers along the way, they depart immediately when they are full, and many of them operate 24 hours a day.
