Rhode Island General Laws Title 17. Elections § 17-19-24.3. Provisional ballot procedures

(a) At all elections, a person claiming to be a registered and eligible voter, but who has failed to provide proof of identity pursuant to § 17-19-24.2 shall be allowed to vote a provisional ballot upon executing a provisional ballot voter's application. All provisional ballots, together with a provisional ballot voter's application, shall be placed in an envelope in the form prescribed by the state board and deposited in a ballot box.

(b) The local board shall examine each provisional ballot application to determine if the signature matches the signature on the voter's registration. If the local board determines that the signatures match, the provisional ballot shall count. If the local board determines that the signatures do not match, the provisional ballot shall not count and the ballot shall remain in the envelope containing the provisional ballot application and the envelope shall be marked “Rejected as Illegal”.
