A vehicle safety system (37) includes at least one image sensor device (17), a control unit arrangement (5, 20, 22) and at least one warning device (11, 12). The image sensor device (17) is arranged to detect eye configurations of a vehicle driver (19). When the warning device (11, 12) is initiated to emit a first warning signal, the control unit arrangement (5, 20, 22) is arranged to determine if the vehicle driver (19) at least partly is looking outside a warning area (24, 25) that at least partly encompasses the warning device (11, 12), and in that case to issue a second warning signal.
