If you're unable to drive to the polls yourself, contact your county election office for options for voting including voting by absentee ballot, or getting a ride from a community service organization that may be providing transportation in your community.

The Polling Place

  • Before you will be permitted to receive a ballot, you will need to present a current ID. If you do not have a photo ID, you can provide a current utility bill, bank statement, paycheck, voter confirmation notice, government check or other government document that shows your name and current address.
    • If you do not have any of the items listed above, you can still vote by requesting and filling out a “Polling Place Elector ID” form.
    • Or, you can vote a provisional ballot and provide one of the items listed above. Your provisional ballot will be counted if you provide one of the items on the list to the county election office by 5:00 p.m. the day after the election, or mail it to the county election office postmarked by the day after the election.
  • If the election officials at the polls determine that you are at the wrong polling place you have several options:
    • If you arrive at the polling place and are told that the address you provide does not match what is in the register because your residence within the county has changed, you may fill out a form to update your information, and vote one time at that precinct and polling place.
    • You can go to the precinct and polling place where you are currently registered to cast your ballot.
    • You can go to the county election office, update your registration information and cast a ballot in your updated precinct.
  • Once you have presented ID, an election judge will have you sign the precinct register.
  • An election judge will give you your ballot(s), and explain how to mark it and what to do with it once you have voted.
  • Each polling place has a voting machine accessible to people with disabilities that allows them to vote independently and privately. If you wish to use this machine, known as an AutoMARK, let the election judge know.
  • You will enter a private voting booth. Instructions on marking your ballot are posted in the booth, and are on the ballot.
  • You do not have to vote on every issue on the ballot. However, if you vote more than once on a candidate or on an issue with only one choice allowable, the vote(s) in that race will not be counted.
  • Turn the ballot over to see if there are candidates or issues on which to vote on the back of the ballot.
  • If you damage a ballot, make a mistake, or change your mind, take the ballot back to the election judge and request a new one. Do not try to erase or cross out as it may cause a vote to not be counted.
  • Do not make any identifying marks anywhere on the ballot.
  • When you have finished voting, follow the instructions given to you by the election judge. Hand the voted ballot to the appropriate election judge. Never hand your ballot to anyone besides an election judge.
