Abstract: A folding ladder is provided for a pickup truck tailgate to assist a person getting into and out of the bed of the truck. The ladder includes a frame hooked to the tailgate, an upper ladder section pivotally connected to the frame, and a lower ladder section pivotally connected to the upper ladder section. The ladder is foldable between a storage position adjacent the tailgate and a use position extending downwardly from the tailgate. The ladder sections reside in a single plane when opened to the use position and nest adjacent the tailgate when in the folded storage position.
