The invention relates to a device (10) for estimating a degree of distraction (62) of a driver during a journey in a motor vehicle (30), and to a corresponding system (18), method, and computer program. An event is identified by an operational input from the driver and is weighted in respect of the expected driver distraction (62). Each event can be assigned a distraction potential, in a parameterisable manner, ranging from not distracting, through neutral, to very distracting. In addition, a time duration, the hold time (58), is determined and corresponds to the expected distraction duration of the specific event for the driver. Should the driver make a number of consistent operational inputs within a short space of time, these are filtered out within a defined time period, the dead time (54), since it is assumed that the driver is not distracted to a greater extent, but only for longer. An index (62) is determined from the events. This index can increase, which means that the driver is currently distracted to an increasing extent, and the index (62) can decrease by defined operational actions, for example heavy acceleration/braking, heavy steering, as a result of which it is identified that the driver is paying attention again to the guidance of the vehicle. If no further events are identified over a parameterisable time, the index (62) reduces to a neutral value (66). If the index (62) exceeds a predefined threshold (64), a distraction message (68) is issued.
