Some things to know if you're headed to the polls:

1. Campaigning is not allowed in the polling place.

2. People may not gather or linger in the polling place or within 100 feet of the building.

3. You cannot display campaign T-shirts, buttons or literature that relates to specific candidates, official political parties or questions on the ballot.

4. Do not initial or sign your ballot or mark it with a sticker.

5. A face covering over the mouth and nose must be worn.

5. Your employer must pay you for the time you need to vote, if it falls within your scheduled work time. Your employer cannot require you to use personal leave or vacation time in order to vote.
