A device is disclosed for displaying information in a vehicle. The device includes a unit for creating a real image containing information relevant to a driver, to be reflected in a reflective viewing surface located directly above the field of vision actively used by the driver to survey the traffic situation, and thereby generating a virtual image. The device further includes a second reflecting surface provided behind or beside the driver's head, with the driver in his or her normal position, at essentially the same level as the viewing surface or higher, an end section of an optical path between the unit and the viewing surface in use extending between said second reflecting surface and the viewing surface. By the optical path extending at least partly in the upper part of the driver's cab, a relatively long (several meters) optical path can be obtained without the need for complex mirror systems. In particular, this applies to commercial vehicles such as lorries and buses, which generally have an essentially vertical windscreen and plenty of free space above and in front of the driver.
