An amusement ride vehicle includes a floor deck assembly slideably mounted inside the body of the vehicle when the vehicle is in motion and telescopically extended away from the body toward a loading platform when the vehicle is at rest. A ramp assembly is mounted to the floor deck assembly near the door of the vehicle and foldably extended away from and at an angle to the floor deck assembly when the ramp assembly is deployed to accommodate a guest in a wheelchair. To promote safety, the ramp and vehicle door preferably have automatic latch mechanisms. To maintain the ride capacity at all times, a companion seat is built into the vehicle body and a conversion seat hidden underneath the companion seat can be deployed if no guest in a wheelchair is being accommodated.
