The state also has Election Day registration, which allows anyone who meets the eligibility requirements to register on Nov. 3 and vote that same day.

This registration, however, is not available at polling locations. There are designated Election Day registration locations in each town that open from 6 a.m. to when the polls close at 8 p.m.

If registering to vote on Election Day, you will register and cast your ballot at the designated Election Day registration location. State officials urge voters to arrive early in case of long lines. Proof of identity and residency will be required to register.
