Transit operators who commented the drafts of the proposed rule requested guidance on the transportability of certain size wheelchairs and mobility devices (e.g., Segways).  The Department of Transportation is responsible for issuing regulations regarding the provision of transportation services to individuals with disabilities under the Americans with Disabilities Act.  The Department of Transportation regulations specify the size of wheelchairs that must be transported.22  The Department of Transportation has also issued guidance on the use of Segways on transportation vehicles.23  The Department of Transportation will conduct a separate rulemaking to amend its regulations so that the accessibility standards included in the regulations are consistent with the revisions to Access Board’s transportation vehicle guidelines.  Comments on transportability of certain size wheelchairs and mobility devices, and other service issues should be submitted to the Department of Transportation when it amends its regulations.
