Ohio polling places should provide touch screen voting machines and have audio adaptations for assisting the blind. There are also adaptations for voters with lack of muscle control.
If you have a disability you may also have assistance by two election officials (of different political parties) or by the person of your choice (except employer or union agent). Poll workers are urged to accommodate voters with disabilities in any way they can.
If the polling place is not accessible for you, you may vote a ballot from your vehicle at all polling places.
For more information, you can utilize the American Association of People With Disabilities (AAPD) resource or your state resource.
