The invention relates to relates a steering system and to a steering method which counteract a mistake that inexperienced drivers frequently make. The invention relates to a system (12, 14, 6) for determining the transversal slip that occurs at the steerable wheels (2). A electronic control system (6) is used to determine an upper threshold value for said transversal slip. If the transversal slip exceeds said threshold value, an augmentation of the angle of lock is counteracted by either limiting said angle of lock and/or outputting a warning signal that can be perceived by the driver.
