R.I. Gen. Laws § 17-19-52: Priority for disabled voters.

Whenever a voter appears at a polling place and that voter has: (1) an obvious medical disability which, in the opinion of the warden, would cause the voter to experience severe discomfort by standing in line, or (2) a certificate from a licensed physician or Christian Science practitioner attesting that the voter has a disability which makes his or her standing in line inadvisable, then that voter may be allowed a priority position for complying with requirements of § 17-19-24 and in each polling place one voting booth shall be designated for priority use by these electors. Other voters may use the voting booth when there are no disabled voters waiting to vote.
