Rhode Island Bans Nothing Called a Plate Cover, But § 31-3-18 Requires Plates Free of Foreign Materials

The negative here can be shown from the structure of title 31 rather than inferred from silence. Chapter 3 of title 31 governs registration and runs to more than 150 sections, including § 31-3-11 on plate contents, § 31-3-12 on visibility and § 31-3-18 on display. Chapter 23, the equipment chapter, and chapter 24, the lighting chapter, together add more than a hundred more. Across all of them the phrase "foreign materials" appears exactly once, in § 31-3-18(b), and no section anywhere in the title uses the words cover, shield or frame in connection with a registration plate. Rhode Island therefore belongs to the group of states whose plate-cover answer is built out of legibility and mounting duties rather than out of a dedicated ban.

Three separate legibility standards apply at once, and a cover has to satisfy all three. Section 31-3-18(b) is the mounting and condition rule: horizontal, securely fastened so the plate cannot swing, no lower than twelve inches (12") from the ground measured from the bottom of the plate, clearly visible in place and position, free from foreign materials, and in a condition to be clearly legible. Section 31-3-12 adds a distance test for daylight, requiring each plate and its letters and numerals, except the year number for which it is issued, to be of sufficient size to be plainly readable from a distance of one hundred feet (100') during daylight. Section 31-24-9 adds the night test: either the tail lamp or a separate lamp must illuminate the rear plate with a white light and render it clearly legible from a distance of sixty feet (60') to the rear, and that lamp must be wired to light whenever the head lamps or auxiliary driving lamps are on. A tinted cover that passes in daylight can still fail the sixty-foot night standard, because it dims the very illumination the section requires.

Frames create a second, less obvious problem in Rhode Island. Section 31-3-18(d) requires vehicles registered as passenger, commercial, trailer, motorcycle, suburban, farm, combination, taxi, radio operator, camper, public, racer tow, jitney and antique to display the plate as described in § 31-3-11, and § 31-3-11 requires the plate to carry the registration number, the name of the state along the top, which may be abbreviated "R.I.", the year number or expiration date, and the words "Ocean State" printed along the bottom for private passenger plates. Plates of every other type must instead carry the plate type printed along the bottom. A dealer frame that covers the bottom band therefore hides content the statute requires the plate to display, and on a commercial or jitney plate it hides the plate type itself.

Two further points close out the picture. Section 31-3-18(a) requires two plates on most vehicles, one in the front and the other in the rear, with motorcycles, trailers, transporter and in-transit vehicles, bailees and dealer vehicles carrying a rear plate only, so a Rhode Island passenger car must keep both readable. And § 31-3-36 requires an owner whose plate is lost, mutilated or has become illegible to apply immediately for a duplicate, substitute or a new registration number as the Division of Motor Vehicles determines, which is the remedy for a plate that a corroded or clouded cover has already damaged.

I. Gen. 1-4. 00, so a single obscured plate can support two civil charges. These are civil violations rather than crimes and are handled administratively through the Rhode Island Traffic Tribunal. A plate that cannot be read also removes the practical defense to other registration offenses: § 31-8-1 makes it an offense to operate, or for an owner knowingly to permit the operation of, a vehicle without the required evidences of registration. Beyond the ticket, § 31-38-2 allows the director of the Department of Revenue, state and local police and designated Division of Motor Vehicles staff to stop a vehicle at any time for inspection, issue a written notice requiring the defect to be corrected and approved within five days, and suspend the registration if the notice is not complied with, with suspension mandatory after three notices for the same defect in twelve months.
