Taxis, which must be painted yellow and equipped with working meters, can be flagged down on most streets in every city and town throughout Bulgaria. They can be very cheap, but rates do vary. Taxis can be chartered for longer trips at negotiable rates, which you can approximate by working out the distance and taxi rate per kilometre, plus waiting time.
All drivers must clearly display their rates on the taxi’s windows. These rates are divided into three or four lines:
Some drivers try to overcharge unwary foreigners by claiming the meter ‘doesn’t work’ (it must work by law) or offering a flat fare (which will always be at least double the proper metered fare). Dishonest drivers congregate outside airports, train and bus stations and big city centres and in the resorts along the Black Sea coast. Negotiating a flat fare only makes sense if you are asking for a multistop journey, or if waiting time needs to be factored into a day trip by taxi.
