Abstract: A method for operating a light-based driver assistance system of a motor vehicle, wherein via at least one headlight of the motor vehicle, a light distribution is projected onto the roadway in front of the motor vehicle. The light distribution produces a lane marking, the width of which is essentially equal to the vehicle width of the motor vehicle and the course of which corresponds to a predicted lane course when the motor vehicle is driving. The method steps are carried out continuously when driving through a curve: predicting the lane course when driving through the curve, determining the point of intersection of the inner lane boundary with the light field limitation of a light field projectable onto the roadway when driving through the curve, setting a distal boundary of the lane marking, and projecting a light distribution onto the roadway in front of the motor vehicle.
