R.I. Gen. Laws § 31-28-6: Overtime parking by persons with a disability exempt from fees.

No penalty shall be imposed upon any person with a disability issued a disability parking privilege placard or sticker pursuant to § 31-28-7, 31-27-7.1 or 31-29-5, nor from the motor vehicle transporting the person with a disability, provided that upon that vehicle there is displayed a disability parking placard or sticker for parking on the highways or in a space for a longer period of time than other persons are permitted to park on the highways or in a space. Nothing in this section shall be deemed to authorize that person to park in any place at any time where parking is prohibited.
