Legal Tint Limit in Louisiana: VLT, Exemptions, and Fines

The legal tint limit in Louisiana is 25% visible light transmission (VLT) on the front side windows, 25% on the rear side windows, and 12% on the rear windshield for standard passenger cars. SUVs, trucks, vans, and other multi-purpose vehicles follow the same 25% rule on the front sides but have no darkness limit on any window behind the driver. The windshield itself can carry only a non-colored transparent strip across the top five inches. Getting the numbers wrong can mean fines up to $350 and a failed state safety inspection.¹

What VLT Means and How Louisiana Measures It

VLT is the percentage of outside light that passes through your window film and the glass together. Lower number, darker window. A film rated at 25% VLT lets through a quarter of the light hitting it; 12% lets through about an eighth. The limits in Louisiana Revised Statute 32:361.1 apply to the combined film-plus-glass reading, which is what a police officer’s tint meter actually measures at the window.¹

Tint Limits for Sedans and Other Passenger Cars

For a standard passenger car — sedan, coupe, hatchback — the rules work out window by window:

Windshield: no tint film, but a non-colored transparent strip is allowed on the top portion so long as it extends no more than five inches down. Red and amber strips are prohibited.
Front side windows: at least 25% VLT.
Rear side windows: at least 25% VLT.
Rear windshield: at least 12% VLT.¹

The 12% rear windshield figure is where sedans get the most freedom. It’s dark enough that you’ll want to rely on side mirrors at night rather than looking straight through.

Tint Limits for SUVs, Trucks, and Vans

Trucks, SUVs, vans, motor homes, and buses follow a different standard behind the driver. Front side windows still need at least 25% VLT, matching passenger cars. But every window behind the driver has no minimum light transmission requirement, so you can apply film of any darkness to those surfaces.¹

The practical result: the same 5% “limo tint” on the rear windows is legal on an SUV and a citable violation on a sedan. The windshield strip rule stays the same regardless of vehicle type.

Reflectivity and Color Rules

Darkness isn’t the only way to fail. All window film in Louisiana must stay at or below 20% luminous reflectance, and that limit applies to every tinted window, not just the front. Mirror or chrome-look film typically exceeds it.¹

Red and amber tint colors are banned outright. Those shades are reserved for emergency and warning lights.¹

Fines and Inspection Consequences

Louisiana escalates driver fines for repeat offenses:

Shops that sell or install illegal film face steeper penalties: $1,000 for a first violation, $2,000 for a second, and a ban from the business after a third conviction.¹

Tint is also checked at the state’s periodic safety inspection. If your film is too dark or too reflective, the vehicle won’t pass and won’t receive a valid inspection sticker until the tint is brought into compliance or stripped.

Medical Exemption for Darker Tint

Drivers with qualifying sun-sensitive medical conditions can apply for an exemption under RS 32:361.2. The exemption covers not just the vehicle owner but also a spouse or family members authorized to drive the vehicle.²

To qualify, a Louisiana-licensed optometrist, physician, ophthalmologist, or dermatologist must sign an affidavit confirming that sunlight exposure creates a medical need for darker film. The condition has to be recognized in the World Health Organization’s ICD-9-CM classification. For a photophobia diagnosis specifically, the doctor must explain why sunglasses alone are inadequate and why the darker tint won’t impair night driving.²

Two requirements catch applicants off guard. You must sign a notarized release letting the state access your related medical records, and the affidavit includes a declaration that you have not been convicted of a drug offense or violent crime, authorizing Louisiana State Police to run a criminal history check.³

The affidavit form comes from the Louisiana Office of State Police, which reviews each application and may consult the Louisiana Medical Advisory Board. If approved, the Department of Public Safety and Corrections issues a decal that must stay prominently displayed on the vehicle, and you have to keep a copy of the approved affidavit inside. Most exemptions come up for review every three years. Light-sensitive porphyria is the one condition that qualifies for a lifetime exemption, lasting as long as you own the vehicle.²

The Installer Certification Label

Every professional installation in Louisiana must include a certification label in the lower right corner of the driver’s side window. The label can be no larger than one and a half square inches, and it goes between the film and the glass so it can’t be peeled off without removing the tint. It has to show the installer’s name and the city where the business is located.¹

Before you leave a tint shop, confirm that label is in place. Inspectors look for it, and a missing label raises questions about whether the film is legal even when the darkness itself appears compliant.

Driving Into Other States

Louisiana’s 25% front-side limit is more permissive than many neighboring states. When you drive into a state with a stricter limit, you’re generally subject to that state’s tint laws while operating your vehicle there, and no federal reciprocity rule shields out-of-state drivers from local enforcement. A medical exemption granted by Louisiana isn’t automatically recognized elsewhere either. If you travel often, check the rules of the states you drive through, especially when your windows sit right at Louisiana’s legal floor.
