Abstract
A foldable ramp for use with vehicles wherein the ramp has a base with an arch plate for eliminating the step up to the ramp surface and an arched bridge to eliminate the step from the top of the ramp to the bed of a vehicle. A foot at the end of the arched bridge is pivotable and allows the ramp to engage the vehicle bed with a flat portion for stably engaging the truck. An adjustable belt connected between the vehicle and the ramp secures the ramp to the vehicle and prevents slipping. The ramp is foldable along its length for ease of storage. The ramp may have one bi-fold ramp for a short wheelbase use or narrow need uses, a tri-fold ramp for wider wheelbase use or two separated bi-fold ramp sections for wide wheelbase uses.
