Each linguistic performance also has a function. In other words, using language means fulfilling a purpose. Therefore, the teaching of functional language comes to the forefront in contemporary foreign language teaching. In this context Common European Framework of Reference for Languages, the fundamental reference for language teaching in Europe, advocates the necessity of teaching the language functions that are based on real life communication rather than predetermined linguistic structures. As it is understood, it is aimed to improve students' communication skills in contemporary foreign language teaching. In order to achieve this aim, first of all, functional linguistic performance in social life areas should be described. In this study, it is aimed to determine the functional linguistic performance in public transport vehicles which is one of the social life areas. In this way, it is aimed to provide a database for teaching Turkish as a foreign language. In this qualitative study, observation method was used. Observation form was used as data collection tool. Data were collected from conversations in minibuses and buses in Adana and Mersin. Data were analyzed based on the qualitative content analysis steps. Three main functions have been identified in urban public transport: imparting and seeking information, deciding on and managing courses of action (suasion), and socialising.
