ABSTRACT:
With this device for positioning motor vehicles (F) in front of vehicle washing plants, especially portal washing plants, at least one transmitting-/receiving device (5, 6) in the portal is assigned to each terminating plane (E1, E2), which portal has a clear space of a predetermined clearance width (D), which clear space is delimited laterally by imaginary, substantially vertical terminating planes (E1, E2) extending in the direction of movement. Said transmitting-/receiving device emits signals, which extend substantially in the terminating plane (E1, E2) in the space in front of the portal (1), and receives said signals. For each terminating plane (E1, E2) there is provided one display unit (9, 10) which is influenced by the associated transmitting-/receiving device (5, 6) and is located in the field of vision of the driver such that, when the received signals change as a result of vehicle parts (4) protruding into the respective terminating plane (E1, E2), the associated display device (9, 10) is activated.
