This paper argues that conversation analysis has largely neglected the fact that meaning in interaction relies on inferences to a high degree. Participants treat each other as cognitive agents, who imply and infer meanings, which are often consequential for interactional progression. Based on the study of audio- and video-recordings from German talk-in-interaction, the paper argues that inferences matter to social interaction in at least three ways. They can be explicitly formulated; they can be (conventionally) indexed, but not formulated; or they may be neither indexed nor formulated yet would be needed for the correct understanding of a turn. The last variety of inferences usually remain tacit, but are needed for smooth interactional progression. Inferences in this case become an observable discursive phenomenon if misunderstandings are treated by the explication of correct (accepted) and wrong (unaccepted) inferences. The understanding of referential terms, analepsis, and ellipsis regularly rely on inferences. Formulations, third-position repairs, and fourth-position explications of erroneous inferences are practices of explicating inferences. There are conventional linguistic means like discourse markers, connectives, and response particles that index specific kinds of inferences. These practices belong to a larger class of inferential practices, which play an important role for indexing and accomplishing intersubjectivity in talk in interaction.

Building on а corpus of 70 hours of German driving lessons, this paper studies the use of declaratives vs. imperatives for instruction. It shows how these linguistic resources are adapted to different praxeological, temporal and participant-related environments. Declaratives are used for first instructions, task-setting and post- trial discussions. They exhibit complex syntax and do not call for immediate compliance. Their high degree of explicitness conveys how the action is to be carried out. Imperative instructions overwhelmingly correct ongoing actions of students or respond to their failure to produce expected actions. They exhibit minimal argument structure. They are reminders which presuppose that the student monitors the scene and can perform the action unproblematically. They index that requests have to be complied with immediately or even urgently.

In this article we pursue a systematic and extensive study of overtaking in traffic as an interactional event. Our focus is on the accountable organisation and accomplishment of overtaking by road users in real-world traffic situations. Data and analysis are drawn from multiple research groups studying driving from an ethnomethodological and conversation analytic perspective. Building on multimodal and sequential analyses of video recordings of overtaking events, the article describes the shared practices which overtakers and overtaken parties use in displaying, recognizing and coordinating their manoeuvres. It examines the three sequential phases of an overtaking event: preparation and projection; the overtaking proper; the re-alignment post-phase including retrospective accounts and assessments. We identify how during each of these phases drivers and passengers organize intra-vehicle and inter-vehicle practices: driving and non-driving related talk between vehicle- occupants, the emerging spatiotemporal ecology of the road, and the driving actions of other road users. The data is derived from a two camera set-up recording the road ahead and car interior. The recordings are from three settings: daily commuting, driving lessons, race-car coaching. The events occur on a variety of road types (motorways, country roads, city streets, a race track, etc.), in six languages (English, Finnish, French, German, Italian, and Swedish) and in seven countries (Australia, Finland, France, Germany, Sweden, Switzerland, and the UK). From an exceptionally diverse collection of video data, the study of which is made possible thanks to the innovative collaboration of multiple researchers, the article exhibits the range of practical challenges and communicative skills involved in overtaking.
