The emergence of the automobile in Belgium from 1895 onwards brutally disrupted the traditional social order on the roads, transforming social practices and the order of society from the mundane-the everyday use of transport-to the more rarified-urban planning and the use of public space. In this article, we will deal with the earliest history of motorization in Belgium. We will analyze motorization as a process of interaction between a specific set of social actors, and focus on its outcome: modern traffic policy as a conflict-management strategy. It is argued that traffic policy evolved from an originally moral strategy into a technical strategy, as engineers and the public road administration introduced Foucauldian approaches in order to discipline the traffic system.
