Taxicabs are usually distinguished by small company logo stickers on bonnet and doors and an illuminated "taxi" sign on the roof (the internationally recognised word "taxi" is almost always used, rather than the Norwegian word "drosje"; the term "maxitaxi" is used informally to refer to minibuses used as taxis). There is no particular colour for taxicabs though various shades of black and silver are the most popular choices of colour. Fares are always metered, although there may be fixed tariffs for certain journeys such as airport-to-city-centre.
