A ramp assembly includes a platform that may be positioned adjacent to a door of a vehicle. The platform is positioned to be longitudinally coextensive with the vehicle thereby facilitating a disabled person to enter the vehicle. A plurality of legs is removably attached to the platform such that each of the legs may abut a support surface. A ramp is slidably coupled to the platform. The ramp is positionable in a deployed position having the ramp extending between the platform and the support surface. Thus, the ramp may facilitate a wheelchair to be rolled onto the platform thereby facilitating the disabled person to enter the vehicle. The ramp is positionable in a stored position having the ramp being stored within the platform.
