A patient support apparatus includes a support structure having a base and further includes an indication system having one or more clearance sensors configured to detect clearance within a clearance zone between the patient support surface and a floor surface and are also configured to generate one or more clearance signals corresponding to the detected clearance. The indication system also includes a controller coupled to the clearance sensors that is configured to receive the one or more clearance signals and generate an output based upon the received clearance signals. A display coupled to the controller is configured to receive the generated output and generate a visual clearance indication corresponding to the detected clearance within the clearance zone, or in specific predefined portions of the clearance zone, that is viewable in a viewing area of the display.
