A tractor vehicle is provided with a side skirt (6) which is configured, when the tractor vehicle is in a working state, to partly delineate laterally a space (4) under a semitrailer (2). The tractor vehicle (1) is provided with an elongate element (11) adapted to extending in the tractor vehicle's longitudinal direction along the side skirt and to being movable relative to the side skirt. The element is movable between at least one active position in which, in the tractor vehicle's working state, the element partly bridges the distance between an upper edge (13) of the side skirt and a lower edge (14) of said semitrailer, thereby serving as an upward continuation of the side skirt, and an at least partly inactive position in which its upper boundary (15) is at a greater distance from said lower edge of the semitrailer than in the active position. A unit is provided to control the movement. |
