An accessibility system for providing access into or out of a vehicle includes a pan defining a securement area. The pan includes a first end, a second end, and a support surface. A ramp assembly includes a first segment and a second segment hingedly coupled to the first segment. The ramp assembly is pivotally coupled to and deployable from the pan near the second end. A tailgate assembly is detachably secured and pivotally coupled to the pan such that during deployment of the ramp assembly, the ramp assembly is pivotable about a first axis and the tailgate assembly is pivotable about a second axis parallel to and offset from the first axis.
