An operable ramp is moveable between a raised (step) position and a lowered (ramp) position. The operable ramp includes a first panel rotatably coupled about a first axis, the first axis that moves back and forth as the operable ramp reciprocates between the raised and lowered positions. A second panel is rotatably coupled to the first panel and extends downward from the first panel in the raised position. The second panel also rotates about a fixed second axis. The first and second panels cooperate to provide an inclined surface when the operable ramp is in the lowered position. A linkage selectively rotates the first panel about the first axis. The operable ramp further includes a third panel rotatable about a fixed third axis. The third provides a surface between the first panel and a fixed panel when the operable ramp is in the raised position.
