What is a Provisional Ballot?

If you are a registered voter and you forget your ID at the time of casting your vote, you may be given a provisional ballot and given some time to verify your identity with the election officials, so that your vote can be counted. In addition, a provisional ballot may be used so as not to deny eligible voters their rights should their names be left off the voting list in error. It is also used to protect the integrity of the voting system.
