ABSTRACT:
A ramp for a vehicle comprises an elongated track with a leading end and a trailing end. The leading end engages a flatbed platform of a vehicle, and the trailing end engages a ground surface so that there is a slope between the leading and trailing ends when the ramp is in a first usage. The elongated track is constituted by multiple engaging elements. The elements are movable relative to each other so that the elements are capable of being packed in a stack to define a platform for a wheel of a vehicle. This permits raising of the wheel of a vehicle above the ground level. There is a hinge between adjacent elements, and the elements of the ramp are hinged at opposite ends for relative folding to permit for a stacked relationship about adjacent ends.
