Abstract: The trailer and flatbed ladder apparatus provides ladder access to a trailer and to a flatbed. The apparatus is highly portable by way of being hinged between the upper and lower sections and due to the tubular construction. The apparatus may therefore be easily and space efficiently stored on and within a truck, bed, or trailer. The apparatus is removably positionable in a plurality of locations around a flatbed and trailer, wherever a stake pocket exists. The stake provides positive non-slip fit to a trailer and flatbed that negates unintentional movement and removal, thereby ensuring safety. Full pivot is provided between the stake and sleeve and the upper section. The apparatus removably fits snugly within the existing stake pockets of a flatbed and trailer due to the stake square outer corners and rounded inner corners that match existing stake pockets.
