In a collision the truck will often wedge a car in a deadly trap. To prevent this and to maximise the effect of car crumble zones, Volvo Trucks has developed the Front Under-run Protection System (FUPS).
FUPS is standard on the Volvo FH and the Volvo FM models. Using a 200 mm deep crumble zone, the penetration of the car's compartment is considerably reduced. FUPS increases the survival rate of the car's passengers. Additionally the truck bumper is located at the same height as that of a typical car bumper, so that the deformation zone of the car can be fully utilised.
