49 CFR 39.93 - What wheelchairs and other assistive devices may passengers with a disability bring onto a passenger vessel?
(a) As a PVO subject to Title III of the ADA, you must permit individuals with mobility disabilities to use wheelchairs and manually powered mobility aids, such as walkers, crutches, canes, braces, or other similar devices designed for use by individuals with mobility disabilities in any areas open to pedestrian use.
(1) As A PVO subject to Title III of the ADA, you must make reasonable modifications in your policies, practices, or procedures to permit the use of other power-driven mobility devices by individuals with mobility disabilities, unless you can demonstrate that a device cannot be operated on board the vessel consistent with legitimate safety requirements you have established for the vessel.
(2) In determining whether a particular other power-driven mobility device can be allowed on a specific vessel as a reasonable modification under paragraph (b)(1) of this section, the PVO must consider:
(i) The type, size, weight, dimensions, and speed of the device;
(ii) The vessel's volume of pedestrian traffic (which may vary at different times of the day, week, month, or year);
(iii) The vessel's design and operational characteristics (e.g., the size and balance requirements of the vessel, the density and placement of stationary devices, and the availability of storage for the device, if requested by the user);
(iv) Whether legitimate safety requirements can be established to permit the safe operation of a device in the specific vessel; and
(1) As a PVO subject to Title III of the ADA, you must not ask an individual using a wheelchair or other power-driven mobility device questions about the nature and extent of the individual's disability.
(2) You may ask a person using an other power-driven mobility device to provide a credible assurance that the mobility device is required because of the person's disability. In response to this inquiry, you must accept the presentation of a valid, State-issued disability parking placard or card, or State-issued proof of disability as a credible assurance that the use of the other power-driven mobility device is for the individual's mobility disability. In lieu of a valid, State-issued disability parking placard or card, or State-issued proof of disability, a PVO shall accept as a credible assurance a verbal representation not contradicted by observable fact, that the other power-driven mobility device is being used for a mobility disability.
(d) As a PVO subject to Title II of the ADA, you must follow the requirements of paragraphs (a) through (c) of this section. In addition, any restriction you impose on the use of an other powered mobility device on your vessel must be limited to the minimum necessary to meet a legitimate safety requirement. For example, if a device can be accommodated in some spaces of the vessel but not others because of a legitimate safety requirement, you could not completely exclude the device from the vessel.
(e) As a PVO, you are not required to permit passengers with a disability to bring wheelchairs or other powered mobility devices into lifeboats or other survival craft, in the context of an emergency evacuation of the vessel.
