Window Tint Laws in Louisiana (2026): Big Changes You Need to Know
Louisiana just made it easier to tint your car windows. The rules changed in 2025. If you haven’t checked the new limits, now is the time.
This guide covers everything you need to know. Legal tint levels, penalties, exceptions, and more. Keep reading.
What Is Window Tint Law?
Window tint law controls how dark you can make your car windows. It sets limits on how much light must pass through the glass.
These rules exist for safety. Police need to see inside vehicles during traffic stops. Drivers need to see clearly on the road.
Pretty straightforward, right?
Understanding VLT: The Key Number
You’ll see the term VLT everywhere when it comes to tint. It stands for Visible Light Transmission.
VLT is just a percentage. It tells you how much light passes through your window. A higher number means lighter tint. A lower number means darker tint.
So 25% VLT is darker than 40% VLT. It lets in less light. Got it? Good.
Louisiana’s Big 2025 Law Change
Okay, this part is important. Louisiana changed its tint law in 2025.
For years, front side windows had to let in at least 40% of light. That changed on August 1, 2025. Now front side windows only need to allow 25% VLT.
That’s a significant jump toward darker tint. Louisiana is now more tint-friendly than it used to be.
The law that made this happen is called Act 143 of 2025. It updated Louisiana Revised Statutes section 32:361.1. If you tinted your car before this change, your tint might now be perfectly legal.
Legal Tint Limits for Sedans and Passenger Cars
Let’s break down the exact numbers for regular passenger cars.
Your windshield can only have non-reflective tint. It must stay above the manufacturer’s AS-1 line. That’s usually the top five inches of the glass. Nothing below that line.
Your front side windows, the driver and passenger windows, must allow more than 25% VLT. That’s the new 2025 rule.
Your rear side windows must also allow more than 25% VLT. Same limit as the front.
Your rear window must allow more than 12% VLT. That’s darker than the sides. Makes sense since it’s further from the driver’s view.
Legal Tint Limits for SUVs, Vans, and Trucks
Here’s where it gets interesting. SUVs, vans, trucks, and multipurpose passenger vehicles get a little more freedom.
Front side windows still need more than 25% VLT. Same rule as sedans.
But the windows behind the driver? Any darkness is allowed. No VLT limit at all.
The rearmost windows, like cargo glass or hatch glass, can also be any darkness. Total blackout if you want.
This is a big deal if you drive an SUV or van. You have a lot more options for your back windows.
Reflectivity Rules
Tint can make windows look shiny or mirror-like from the outside. Louisiana limits that too.
Your tint cannot be more than 20% reflective. This applies to all windows. No mirror-finish tint that could blind other drivers.
Most standard tint film is well under 20% reflectivity. But it’s worth double-checking before you buy.
Colors, Stickers, and Certification
Louisiana bans certain tint colors. Red tint is not allowed. Amber tint is not allowed either.
Stick to neutral tones. Gray, charcoal, and similar shades are fine.
Here’s something most people miss. Tint manufacturers must certify that their film meets Louisiana’s standards. Always ask your installer if they’re using certified film.
Your installer must also place a compliance sticker on your driver’s side window. It goes between the film and the glass. This sticker proves your tint is legal. Don’t let anyone skip this step.
Penalties for Illegal Tint
So what happens if your tint doesn’t meet the rules? Let’s talk about it.
A first offense will cost you $150. It’s not catastrophic, but it’s not fun either.
A second offense jumps to $250. The state starts taking it more seriously.
A third or subsequent offense costs $350. And it keeps going up from there.
Think of it like a parking ticket that gets more expensive each time. Not worth the risk.
On top of the fine, your car could be flagged for further inspection. You might be required to remove the tint. That adds more time, hassle, and money to the situation.
Louisiana law enforcement uses portable tint meters during traffic stops. Even if your tint is slightly off, like 22% when the limit is 25%, you can get a ticket. Don’t assume “close enough” works here.
Medical Exemptions
Wait, it gets better. Louisiana actually does have a medical exemption for tint.
Some sources say there are no exemptions. That’s outdated information. Louisiana Revised Statutes section 32:361.2 allows medical exceptions.
If you or a family member has a medical condition that makes sun exposure harmful, you can apply. Conditions like lupus, porphyria, photophobia, albinism, and other light-sensitive conditions may qualify.
Here’s what you need to do. Get an affidavit signed by a licensed optometrist, ophthalmologist, dermatologist, or other physician. The Louisiana State Police provide a specific affidavit form for this purpose.
You must keep a copy of the affidavit in the vehicle at all times. The state will also issue a special decal for your car. Display it prominently.
Medical exemptions typically last three years. After that, you need to renew. If you sell the car, the new owner must remove the tint unless they also qualify for an exemption.
Honestly, this is the part most people don’t know about. If you have a qualifying condition, don’t suffer in the heat. Look into the exemption.
Older Vehicles: A Special Note
Louisiana tint law applies to vehicles made on or after January 1, 1994. If your car was built before 1994, you are exempt. You need to carry a certificate confirming this.
Not many cars on the road fall into this category. But if yours does, you have more tinting flexibility.
How to Stay Compliant
Wondering how to make sure you’re on the right side of the law? Let me walk you through it.
First, confirm the VLT percentage before installation. Ask your tint shop for the exact number. Don’t guess.
Second, remember that factory tinted glass already blocks some light. Adding film on top of factory tint stacks the effect. That combo could push you under the legal limit even with light film. Your installer should account for both the glass and the film together.
Third, get the compliance sticker installed. Make sure it’s on the driver’s side window between the glass and film.
Fourth, ask if the film is certified for Louisiana. A reputable shop will know this.
Fifth, keep your receipt. If you’re ever pulled over, it helps to show documentation of what was installed.
Most tint shops in Louisiana know these rules well. A good installer will guide you through everything. Don’t be afraid to ask questions.
What About Police and Government Vehicles?
Law enforcement vehicles are exempt from tint laws in Louisiana. They can use any level of darkness on any window. This exemption is written directly into the statute.
So if you see a blacked-out police cruiser, that’s legal. You just can’t do the same on your personal vehicle.
