3. Be sure you’re registered

Nov. 5 was the last day to register to vote for the 2016 general election. To check if you are registered before you head to the polls, visit ncsbe.gov

4. Know what to bring with you.

Based on the way a voter registered, they may have to show some type of identification. A voter record may be flagged as having to show ID, Whitehurst said, while a first time voter will have to show some type of name and address that shows their date of record.

5. Plan ahead

If you want to be certain, check out the Board of Elections website. Sample ballots, including the names of candidates running for election are available at OnslowCountyNC.gov/Elections/.

6. No selfies

If you plan to take a selfie, wait until you’re in the car. Whitehurst previously told The Daily News that selfies are not allowed at the voting station.

7. Not official

Election results will remain unofficial until the canvass on Nov. 18.
