What Is Legal Tint in Louisiana? Window Tint Laws Explained

Window tint laws in Louisiana follow the same basic framework used across most of the U.S. — but the specific percentages, placement rules, and exceptions are unique to the state. If you're buying a vehicle with tint already installed, adding tint to a new car, or just trying to understand whether your current setup is street-legal, here's how Louisiana's rules generally work.

How Window Tint Is Measured

The key measurement is VLT, or Visible Light Transmission. This is the percentage of visible light that can pass through your window glass and tint film combined. A higher VLT percentage means more light gets through — and lighter tint. A lower number means darker tint.

So 50% VLT is relatively light. 5% VLT (sometimes called "limo tint") is very dark — nearly opaque from the outside.

When tint laws reference a percentage, they're setting a floor: the film must allow at least that much light through. Going darker than the legal limit puts you out of compliance.

Louisiana's Window Tint Requirements by Window

Louisiana law distinguishes between different windows on the vehicle, and the rules vary depending on whether you're driving a passenger car or a multipurpose vehicle (MPV) — a category that generally includes SUVs, vans, and trucks.

Passenger Cars (Sedans, Coupes, Hatchbacks)

Multipurpose Vehicles (SUVs, Vans, Trucks)

This distinction matters quite a bit. If you drive an SUV or pickup, you have significantly more flexibility with rear and back side windows than a sedan driver does.

Reflectivity Rules

Louisiana law also limits how reflective tint can be. Metallic or mirrored films that create a high-glare appearance are restricted. Both passenger cars and MPVs are generally limited to tint that is not more than 20% reflective on front and back side windows. Tint that mirrors or appears overly metallic is typically non-compliant regardless of its VLT rating.

What About the Windshield?

Tint on the windshield is tightly restricted in Louisiana — as it is in virtually every state. The only permitted tint is a non-reflective strip along the top, limited to the uppermost 5 inches. This is sometimes called an "eyebrow" strip, and its purpose is to reduce sun glare without obstructing the driver's view of the road.

Full windshield tint, colored tint, or reflective film on the windshield is not permitted. 🚫

Medical Exemptions

Louisiana does allow medical exemptions for individuals with documented conditions that require reduced sun exposure — such as lupus, certain skin conditions, or photosensitivity disorders. With an approved exemption, darker tint than the standard limits may be permitted on certain windows.

Exemptions typically require a statement from a licensed physician and must be carried in the vehicle. The process and documentation requirements are set by the state, and specifics can vary. If this applies to you, the Louisiana Office of Motor Vehicles (OMV) is the right place to get current requirements directly.

Color Restrictions

Louisiana restricts certain tint colors. Red and amber tint are not permitted on any vehicle window. Other colors — including gray, smoke, charcoal, and green-tinted film — are more commonly used and generally acceptable as long as VLT and reflectivity requirements are met.

How Tint Is Enforced ⚠️

Louisiana law enforcement can cite drivers for non-compliant tint during a traffic stop. Tint meters — handheld devices that measure VLT — can be used roadside. If your tint reads below the legal limit for that window, you can be cited regardless of where or by whom the tint was installed.

This is worth keeping in mind if you're buying a used vehicle. A previous owner's choices about tint become your compliance problem once you take ownership.

What Shapes Your Outcome

Even within Louisiana, what counts as "compliant" tint depends on several variables:

• Vehicle type — sedan vs. SUV vs. van changes which rules apply to back windows
• Window position — front side windows face stricter limits than rear windows on most vehicles
• Tint already on the glass — factory privacy glass has a built-in VLT; adding film on top of it further reduces light transmission
• Film quality and age — tint can shift color or darken over time, moving a once-compliant install out of range
• Medical status — exemptions change what's legal for a specific driver

The combination of your factory glass, any existing film, and any new film you add all factor into what the meter reads. A professional installer should be able to measure this before and after installation.

Your specific vehicle, the windows in question, and your current setup are the pieces that determine where you land within Louisiana's framework.
