![]() The result may be that the rear part of the truck will enter the passenger compartment of the vehicle with great force, which in turn may cause serious injuries to the passengers of the vehicle. ![]() The reason for this is that during a collision between such a truck and a passenger vehicle there is a risk that the passenger vehicle will penetrate in under (run under) the front or rear part of the truck and thus be jammed between the road surface and the underside of the frame or load carrier of the vehicle. The fact that a truck normally has a relatively large road clearance constitutes a serious risk with respect to road traffic safety. At the front of the vehicle, the road clearance is normally on the order of 40-50 cm. One major reason for this is the need for using the vehicle for driving over rough terrain. ![]() Large vehicles, such as trucks, are currently designed with a relatively large road clearance. The main area of application for the invention is heavy trucks, especially for the purpose of preventing passenger vehicles from penetrating under a truck during a collision. The current invention relates to a method for maneuvering an underrun protection device and an arrangement for an underrun protection (also known as run-under protection) device for a vehicle. Said applications are expressly incorporated herein by reference in their entireties. 2002 which was published in English pursuant to Article 21( 2) of the Patent Cooperation Treaty, and which claims priority to both Swedish Application No. The present application is a continuation patent application of International Application No.
