Voting At The Polls On Election Day


Your voter registration confirmation card lists the location of your polling place. If you've misplaced your card, call your local election administrator to find out where to vote or check your polling place location on-line at My Voter Page.

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 you arrive at the polling place and inform the election officials that you have changed residence but have not updated your voter registration:

  • If your name appears on the register at that polling place, you can vote one last time at that polling place, after filling out a voter registration application with your new residence address;
  • If your name does not appear on the register at that polling place, in order to vote in the election you must go to the county election office, update your registration information and cast a ballot based on your updated residence address, or go to your old polling place and vote one last time at the old polling place.

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 or station. Instructions on marking your ballot are posted in the booth or station, 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 - doing so will invalidate your 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 or place it in the voting system if one is provided. Never hand your ballot to anyone besides an election judge.
