An operable ramp is moveable between a raised position, in which the ramp forms a pair of steps, and a lowered position, in which the operable ramp provides an inclined surface. The operable ramp includes a first panel rotatably coupled about a first axis that moves back and forth when the operable ramp moves between the lowered position and the raised position. A link is rotatably coupled to the first panel about a second axis and is itself rotatable about a fixed third axis. A second panel is rotatably coupled to the link between the second axis and the third axis, and a third panel is rotatably coupled to the second panel about a fourth axis. When the ramp moves between the raised and lowered positions, the fourth axis rotates about a fixed fifth axis. A linkage selectively rotates the first panel about the first axis.
