NASHVILLE (AP) — The Department of Safety will open eight driver service centers Saturday to help voters who need photo identification cards before the Tuesday general election.

Centers will be open 8 a.m. to 4 p.m. in Chattanooga, Cookeville, Dresden, Jackson, Johnson City, Knoxville, Memphis and Nashville. Services that day will be limited to issuing free photo IDs to registered voters and converting non-photo driver's licenses to a version with a picture.

A release from the Safety Department said the centers were chosen based on population and response to Saturday openings before the August primary election.

As of Monday, Tennessee had issued more than 24,000 photo IDs to voters, who this year are required to show photo identification at polling places.
