License Plate Frames Laws: Everything You Need to Know

If you've ever bought a car from a dealership, there's a good chance it came with a branded license plate frame. But is that frame — or the aftermarket one you picked up to protect your plate from rust — actually legal? The answer across the United States is remarkably consistent: it depends on what the frame covers up.

The National Landscape

After reviewing statutes in all 50 states, one pattern stands out: no state flatly bans license plate frames, and no state gives them unconditional blanket approval either. Every single state falls into a "conditional" category — frames are legal as long as they don't obscure information the state requires to remain visible, such as the plate number, the state name, registration stickers, or expiration decals.

That means the real legal risk isn't the frame itself — it's what the frame (or a plate cover used alongside it) ends up hiding. States vary widely in:

What exactly must stay visible — just the numbers, or also the state name, county name, registration stickers, and decals
Whether plate covers (as opposed to frames) are allowed at all — some states ban all covers outright, even clear ones
Whether automated license plate readers (ALPR) or automated enforcement systems are specifically protected
What penalties apply, including a few states with scheduled law changes on the horizon

Since every state lands in the same "conditional" bucket, the real value is in the details — and those details differ enormously from state to state.

The Universal Rule: Frames Are Fine, Obstruction Isn't

The vast majority of states — including License Plate Frames in Alabama, License Plate Frames in Alaska, License Plate Frames in Michigan, License Plate Frames in Nevada, and License Plate Frames in Wyoming — follow a simple formula: plates must remain clearly legible, and frames are allowed as long as they don't cover anything required. These states generally don't call out frames or covers by name in detail; they rely on a general "keep it visible and legible" standard.

Some states in this camp go further by explicitly permitting covers under certain conditions. Georgia allows covers "if colorless and transparent" while requiring that frames and any apparatus not obstruct legibility (O.C.G.A. § 40-2-41). Missouri similarly allows clear covers but effectively bans tinted or smoked ones, since all parts of the plate must be "plainly visible and reasonably clean with reflectivity unimpaired" (Mo. Rev. Stat. § 301.130(5)).

States That Ban Covers Outright

A significant cluster of states have gone further than "keep it legible" and banned plate covers entirely — regardless of tint or transparency:

Illinois: "operating with ANY registration plate cover — including a clear one — is prohibited" (625 ILCS 5/3-413)
Maryland: "all covers, clear ones included, are banned" (Md. Transp. §§ 13-411, 13-411.1)
New York: "all glass and plastic covers are banned regardless of tint" (N.Y. Veh. & Traf. Law § 402(1)(b), § 402(8))
Oklahoma: "all covers banned — clear, translucent, tinted, or opaque alike" (47 O.S. § 1113(A))
Utah: "all plate covers banned outright" (Utah Code § 41-1a-403(2))

Notably, in each of these states, frames themselves remain allowed — it's specifically the cover (a separate plastic or glass shield over the plate) that's prohibited.

States Protecting More Than Just the Number

Many drivers assume the only thing that matters is keeping the plate number visible. Several states explicitly protect more than that:

Iowa requires "a full view of ALL numerals and letters on the plate — including the county and state name" (Iowa Code §§ 321.37(3), 321.38)
New Jersey bans any frame or marker holder that conceals "any part of any marking imprinted on the plate or any part of any insert — which expressly includes the state name, not just the number" (N.J.S.A. 39:3-33)
North Carolina protects "numbers, letters, state name, and sticker month and number" (N.C.G.S. § 20-63(g))
Vermont goes especially far: plates must be "entirely unobscured," a standard specific enough that "ordinary dealer frames that cover the top or bottom border violate it" (23 V.S.A. § 511(a))

If you're in one of these states, that cute dealer frame with a rounded top covering the state name could technically put you on the wrong side of the law.

States with ALPR-Specific Language

As automated license plate readers become more common in law enforcement and toll collection, some states have written that technology directly into their statutes:

California requires plates to remain legible "including to electronic readers," with covers banned outright except for a narrow exception limited strictly to a security cover over the registration tabs (Cal. Veh. Code §§ 5201, 5201.1)
Colorado requires the plate to stay readable "including by automated plate readers" (C.R.S. § 42-3-202)
Pennsylvania permits a frame that "minimally outlines the plate" only if the number and issuing jurisdiction stay identifiable "by an automated enforcement system or police," and separately bars interference with electronic toll collection (75 Pa.C.S. § 1332(b), (b.1))
Texas bans attached material that "distorts angular visibility or automated detection" (Tex. Transp. Code § 504.945)

Notable Outliers and Upcoming Changes

A few states stand out for unusual specifics or laws that are actively changing:

Hawaii is tightening its rules dramatically. Right now, covers are restricted when used to obscure the plate, but starting January 1, 2027, Act 12 will "ban every cover and shield outright, clear ones included, at no less than $1,000 per day" (Haw. Rev. Stat. §§ 249-7(b), 286-73).

Kansas is also mid-transition: as of July 1, 2026, a frame that hides the number, state name, or decal becomes a violation, though the state will issue "warning citations only through December 31, 2026" (K.S.A. 8-15,110).

Florida currently protects "any feature or detail" of the plate through September 30, 2026, but SB 488 will narrow that starting October 1, 2026 to just "the plate number and registration decal" — and will expressly make frames lawful when both stay visible (Fla. Stat. § 320.061, § 316.605, § 320.262).

Mississippi has a quirky carve-out: the tag must stay uncovered, "except that the county name may lawfully be covered" (Miss. Code § 27-19-31).

South Carolina allows a trailer hitch to obscure "up to 2 inches" of the plate — a rare numeric exception in this dataset (S.C. Code § 56-3-1240(D)).

The Bottom Line

Whether you're driving a dealer-branded frame or a decorative aftermarket one, the safest approach anywhere in the country is the same: make sure nothing on your plate is covered up — not the number, not the state name, not the registration sticker, and not the expiration decal. States differ on exactly how much protection they extend and whether covers (as opposed to frames) are allowed at all, so it pays to check your specific state's rules, especially if you're planning to install anything beyond a simple frame.
