The invention relates to a method for limiting a speed in accelerator pedal operation of a commercial vehicle with a speed limiting device that is designed to reduce an engine power and/or fuel supply of the commercial vehicle after reaching a preset maximum vehicle speed (10) independently of the accelerator pedal position as soon as a speed (11) of the commercial vehicle exceeds the preset maximum vehicle speed (10), characterized in that the preset maximum vehicle speed (10) is changed as a function of topography data (2) and/or road information.
