Frantic cars and lorries circulate all day and night and traffic jams make drivers even more anxious. Speed is usually override and a red lights don't mean that a car will stop. As a tourist you should ask for a special drivers licence if you dare to drive. Runs from 6.00 AM to Midnight. Unlimitted distance fare.
Trolley cars are neat, cheap and efficient but there are only few routes.
Coaches are less confortable but they have even a lower rate. A curious mean of transport are the so called microbuses . Their design is pretty uneven, usually unconfortable but practical, since they cover any possible destination. There is a fixed rate in taxis but sometimes you have to deal a reasonable payment. Giving a tip is a good idea because rates are still low.
