Mississippi Window Tint Laws (2026): Legal VLT Limits

In Mississippi, front side windows must allow at least 28% of visible light through (VLT), and back side windows and the rear window generally follow the same 28% floor. Pickup trucks, vans, motor homes, RVs, SUVs, and other multipurpose vehicles get an exception: their windows behind the front two side windows may be tinted as dark as federal law allows for factory-tinted glass on that vehicle, without meeting the 28% floor.

What is the legal tint limit in Mississippi?

Mississippi's window tint law is found at Miss. Code Ann. 63-7-59. The central concept is Visible Light Transmission (VLT): a higher VLT percentage means a lighter film that lets more light in, while a lower VLT percentage means a darker film. Mississippi's 28% VLT floor is moderately permissive compared to states like Minnesota (50%) but is stricter than states like New Mexico (20%) or Texas (25%).

Mississippi applies the 28% standard to front side windows on ordinary passenger vehicles, and to back side windows and the rear window on sedans and coupes. Pickup trucks, vans, motor homes, RVs, SUVs, and other multipurpose vehicles have a separate exemption: the windows behind the front two side windows, including the rear window, may be as dark as the light transmittance authorized for that window and vehicle under federal law before factory delivery, regardless of the 28% floor.

Two further exemptions take entire vehicles outside the 28% rule rather than just certain windows. Subsection (3)(a) exempts school buses, other buses used for public transportation, any bus or van owned or leased by a Mississippi nonprofit corporation, funeral home services vehicles, limousines owned or leased by a private or public entity, government-owned law enforcement or fire department vehicles, and volunteer fire department vehicles. Because that exemption is written against subsection (2) as a whole, it reaches the front side windows too, not only the glass behind them. Subsection (3)(c) separately exempts any other vehicle whose windows were tinted or darkened before factory delivery as federal law or regulations permit.

The figures above describe ordinary passenger vehicles. The vehicle classes listed in subsection (3)(a), such as buses, limousines, funeral home vehicles and government law enforcement or fire vehicles, are outside the 28% requirement on every window.

Because the statute does not specify a measurement tolerance, enforcement follows officer discretion and meter readings. Choosing a film rated at 30% or above gives you a practical buffer against borderline readings.

Windshield tint rules in Mississippi

Mississippi bans tinted film, glazing material, or darkening material of any kind on the windshield, with one exception written into Miss. Code Ann. 63-7-59(1): material designed to replace or provide a sun shield in the uppermost area, as authorized to be installed by manufacturers of vehicles under federal law.

Note that the Mississippi statute does not use the phrase "AS-1 line" that appears in many other states' tint laws. It points instead to the federally authorized factory sun shield zone at the top of the windshield. In practice, installers still treat the AS-1 marking printed on most windshields as the working boundary for that zone, but the legal test is the federal manufacturer authorization rather than the marking itself. If your windshield carries no visible marking, confirm the permissible area with your installer before proceeding.

Mississippi's statute does not set a numeric reflectivity percentage cap or ban particular tint colors, but Miss. Code Ann. 63-7-59(1) categorically bans any glazing material that causes a "mirrored effect" on the front windshield, side wings, or side or rear windows. That prohibition applies regardless of how the film measures on a tintometer. Non-reflective films are the safest choice throughout.

Medical exemptions

Mississippi allows a medical exemption under Miss. Code Ann. 63-7-59(4). A physician licensed to practice medicine in the State of Mississippi must diagnose a physical condition or disease that is seriously aggravated by minimum exposure to sunlight. The document that makes the exemption valid is not the physician's own letter. It is a certificate of medical exemption on a form prepared by the Commissioner of Public Safety, signed by the person on whose behalf it is issued, and displayed prominently on the vehicle dashboard.

Qualifying conditions typically include photosensitive skin conditions such as lupus or xeroderma pigmentosum, severe photophobia or certain eye disorders, and other documented medical needs where ultraviolet or visible light exposure worsens the condition. The exemption is written at the vehicle level rather than window by window: it permits tint that would otherwise violate the section upon the windshield or windows of the motor vehicle, and it covers any vehicle the qualifying person owns, operates, or regularly travels in as a passenger, not only a vehicle titled in that person's name.

Getting the certificate is a counter transaction, not something the physician can hand you directly. The certificate is issued free of charge through the offices of the tax collectors of the counties. The applicant must present two things to the issuing official: an affidavit signed personally by the applicant and signed and attested by a physician, stating the condition or disease that entitles the applicant to the exemption, and proof of ownership of the vehicle, or a signed affidavit by the owner of a vehicle operated for the applicant's use. Only once the county office issues that state form is there anything valid to display on the dashboard.

How tint is measured and certified in Mississippi

Mississippi's compliance sticker requirement does not reach every tinted vehicle. Under Miss. Code Ann. 63-7-59(6), DPS issues labels to official tint inspection stations for vehicles required to be inspected in this state that have a window tinted or darkened after factory delivery, so glass that came tinted from the factory needs no label. The sticker is a self-destructive, pressure-sensitive label no larger than one inch square, affixed to the lower left corner of the windshield. Self-destructive labels are designed to tear apart if anyone attempts to remove them, preventing a sticker from being transferred from a compliant vehicle to a non-compliant one. The same subsection requires the inspection station to test the window's actual light transmittance before affixing the label, so the label is not simply applied by whichever shop installs the film unless that shop is an authorized inspection station.

The statute does not specify a measurement tolerance. Officers use tintometers (VLT meters) to measure the film during roadside stops, and readings at or above 28% should satisfy enforcement. Because there is no named tolerance, films rated right at 28% have less margin than in states with a formal plus-or-minus allowance. Choosing a film rated at 30% or above is the conservative approach.

Enforcement authority here is a hard statutory limit, not a matter of local practice. Miss. Code Ann. 63-7-59(12) provides that violations of the section shall be enforced only by law enforcement officers of the Mississippi Department of Public Safety and municipal law enforcement officers of municipalities having a population of two thousand (2,000) or more, on the public roads, streets and highways under their jurisdiction. County sheriff's deputies and officers in municipalities under 2,000 people have no authority to enforce this section at all. The tint standards still apply statewide, but the set of officers who may cite you under this section is narrow.

Penalties for illegal tint in Mississippi

Miss. Code Ann. 63-7-59(10) sets maximum penalties rather than fixed ones: a fine of not more than $1,000, or imprisonment in the county jail for not more than three months, or both. Those maximums apply specifically to installers who apply non-compliant film and to anyone who alters, reproduces, or knowingly misuses a compliance label or medical exemption certificate. An ordinary violation, such as driving with tint darker than 28% and no compliant label, is instead punishable as provided in Section 63-7-7, which makes it a misdemeanor to drive a vehicle that is equipped in any manner in violation of the chapter. Either way, driving with unlabeled or non-compliant tint exposes you to a citation.

The compliance sticker requirement gives officers an immediate enforcement reference. If the lower-left corner of the windshield lacks a self-destructive label on a vehicle that should carry one, the officer can proceed to meter the windows. Bringing the vehicle into compliance and affixing the proper sticker is the surest way to avoid further contact.

Installers who apply non-compliant film share responsibility under the statute. Mississippi's penalty structure creates financial and legal risk for shops that knowingly install film darker than 28% without a valid medical exemption covering the vehicle.

If you want to tint your windows in Mississippi

On an ordinary sedan or coupe, Mississippi's 28% VLT floor applies to the front side windows, back side windows and rear window alike. It is not a universal rule, though: the statute allows darker glass behind the front two side windows on pickups, vans, motor homes, RVs and SUVs, and it exempts whole classes of vehicles such as buses and limousines. For a standard passenger car, choose a film rated at 28% VLT or lighter, and consider going with 30% or above to give yourself a practical buffer given the absence of a formal measurement tolerance in the statute.

After installation, have the film tested and labeled at a DPS-authorized official tint inspection station, which affixes the self-destructive label to the lower-left corner of the windshield only after confirming the window meets the 28% transmittance standard. Ask your installer for documentation confirming the film's rated VLT so you have a manufacturer's spec sheet to supplement the sticker if needed. Keep that documentation in the vehicle for any roadside stop.

If you have a medical condition seriously aggravated by minimum sun exposure, complete the exemption paperwork before installation. Get the physician-attested affidavit first, then take it together with proof of vehicle ownership to your county tax collector's office to be issued the state certificate, and display that certificate prominently on the dashboard at all times when the vehicle is in use.
