Please find more information about accessible voting at the Missouri State Page: How To Vote.
Curbside Voting: Voters with limited mobility can vote “curbside” or outside the polling place. Just go to your polling place and ask someone to go in and ask poll workers to bring a ballot out to you. They should bring you a ballot within a reasonable period of time.
Accessible Polling Places: If you have physical disabilities, and your polling place is not accessible, you may request a different polling place assignment so that you may vote in a more accessible polling place. You may also vote at a central location. Simply contact your local election authority to make this request. You can find your local election authority here or by calling (800)NOW-VOTE.
Accessible Voting Systems: Every polling place must have an accessible voting system for individuals with disabilities including audiovisual accessibility. Accessible systems include an audio ballot to make your selections or the ability to enlarge text so that you can read the on-screen ballot with ease.
Permanent Absentee Voting: If you have a permanent physical disability, you may request to be placed on a designated list so that your local election authority can automatically mail an absentee ballot application directly to you prior to each election. You will need to make this request directly to your local election authority who will send you further information.
