New rules will affect voters in Tuesday's congressional primaries because of a new state law.

All voters will be asked to provide one of the following types of photo ID at their polling place:

S.C. driver's license. Out-of-state licenses will not be accepted.

Another type of S.C. identification card issued by the S.C. Department of Motor Vehicles

S.C. voter registration card with a photo

A federal military ID

U.S. passport

Voters who forget their ID may cast a provisional ballot that will count only if they show their photo ID to their local county election commission prior to certification of the election Thursday.

Voters who do not have a photo ID can get one free from their local county voter registration office. They must provide their name, birth date and the last four digits of their Social Security number.

Voters who have extenuating circumstances that prevent them from getting a photo ID before the election can bring their non-photo voter registration card (the old card without photo) to the polls. They will be allowed to vote after signing an affidavit stating they have a reasonable impediment to obtaining photo ID. Allowable impediments include a religious objection to being photographed, a disability, illness, work schedule, lack of transportation, family responsibilities or any other obstacle the voter finds reasonable.
