Louisiana Bans Plate Covers, Sprays and Electrochromatic Film That Obscure a Plate From Any Angle

The prohibition is broader than a smoked plastic frame. It reaches three separate things: a covering, any substance applied to the plate, and an electronic device or electrochromatic film. The third category is what a spray-on obscurant or a switchable film shutter would be, and Louisiana named it expressly rather than leaving it to be argued under a general legibility clause. The section's history line runs Acts 1962, No. 310, Section 1; Acts 2014, No. 148, Section 1; Acts 2017, No. 46, Section 1, so the modern wording is a recent addition to a statute whose original text is from the 1962 Highway Regulatory Act.

The "unless authorized by the commissioner" opening is a real carve-out, not decoration, but R.S. 32:53 contains no application procedure, no fee and no standard for granting it, so a driver who wants a cover has to obtain that authorization from the Department of Public Safety and Corrections rather than assume a product is legal because it is sold in the state.

The rest of R.S. 32:53(A) sets the physical rules a cover often defeats in practice. Paragraph (A)(2) puts the permanent registration plate on the rear of a trailer, semitrailer, motorcycle or other motor vehicle, with an exception letting a truck over ten thousand pounds gross vehicle weight, or a dump truck, carry it on either the front or the rear, and it defines a dump truck for that purpose as any truck with a bed that raises to dump a load. Paragraph (A)(4) makes clear that mounting the plate on a rear fender is permitted so long as it faces to the rear.

Two neighbouring provisions matter to anyone accessorising a plate. R.S. 32:333 prohibits, for all but antique automobiles, neon lights around license plates or any other lights that obscure the clear view of the plate, and it carries a far heavier penalty than the general equipment default: a fine of not more than one thousand dollars, or imprisonment for not more than six months, or both. And R.S. 32:304(C) requires either the tail lamp or a separate lamp to illuminate the rear registration plate with a white light and render it "clearly legible from a distance of fifty feet to the rear," wired to light whenever the head lamps or auxiliary driving lamps are on. A tinted cover that survives a daylight look can still fail that fifty-foot night-time test.

Enforcement runs through the periodic inspection as well as the roadside stop. R.S. 32:1304(A)(1) requires every motor vehicle, low-speed vehicle, trailer, semitrailer and pole trailer registered in Louisiana to be inspected at least once every other year and not more than twice a year, and R.S. 32:1304(D)(1) lets the secretary suspend the registration of a vehicle that, after notice and demand, is not equipped as the chapter requires.

S. 32:53 sets no penalty of its own, so a plate-cover violation falls to La. S. 32:57(A)(1): a fine of not more than one hundred seventy-five dollars or imprisonment for not more than thirty days, or both, on a first violation, and not more than five hundred dollars or ninety days on a subsequent one. S. S. S. 32:53(A)(2) the vehicle may be immediately impounded. S. 32:333(B) a violation of the neon-and-obscuring-lights ban draws up to one thousand dollars, up to six months, or both. S. S. S. 32:57(D) both remain available.
