The device makes it possible for a driver on an icy road to activate, at least for a limited period of time, controlled grit spreading. The outlet opening (6) of the bin (5) with grit material (4) is closed with two working cylinders (1) and (2) that are covered with a layer of pliable flexible material (3), e.g. plastic foam. After the device is activated the grit material (4) is drawn between the rotating cylinders (1) and (2) and it falls into the chute (8) directed in front of the front wheels of the vehicle. The activation is performed manually by the driver or - in the automatic regime - it can be activated by the control unit connected to ABS. It is also possible to use a regime of moderate spreading (e.g. while driving uphill). The grit material (4) is crushed gravel.
