The polling sites are prepped and ready for a big voter turnout on Election Day. Voting lines are expected to form early, before polls open in Tuesday morning.

Workers expect the polls to stay busy until they close, but there are a couple things you can remember to save time once you get there.

Signs outside the Glenwood precinct in Chattanooga let parents know the rec center will be closed Tuesday -- open for "voting only."

"Long lines, I believe, will occur," said Kerry Steelman, Hamilton County Administrator of Elections.

In the last two presidential elections, more than 140,000 people in Hamilton County cast a ballot, and 2016 is on track to do the same.

This year, a record 73,000 people in Hamilton County voted early. That's nearly 40-percent of the county's registered voters.

Lines on the final day of early voting wrapped around the building. Tuesday, however, is expected to be a little less congested because 81 polling sites will be open county-wide.

"I don't think they'll be quite the length we saw at some of our early voting sites," Steelman said.

Poll workers said the #1 problem on Election Day is voters forgetting their government-issued photo ID. The second most common mistake is showing up at the wrong polling place.

"On Election Day, you must go to the polling site on the address of your permanent registration," said Steelman.

All polling locations in Tennessee are open 8 a.m. - 8 p.m. Polling locations in Georgia are open 7 a.m. - 7 p.m.

Anyone in line by the time polls close will still be allowed to vote.

Voters must also take a valid federal or state photo ID.

Unlike early voting, you must vote at your assigned polling site. Voters can check the Secretary of State's website to double-check their polling location.

If you need a ride to the polls, CARTA is giving free rides to voters all day Tuesday.
