Louisiana Window Tint Laws (2026): Legal VLT Limits
Louisiana Window Tint Laws (2026): Legal VLT Limits
Louisiana law requires front side and back side windows to allow at least 25% of visible light through, a limit lowered from 40% by 2025 Act 143 (effective August 1, 2025). Rear windows must allow at least 12% VLT on all vehicles.
What is the legal tint limit in Louisiana?
Louisiana's window tint rules are governed by La. R.S. 32:361.1. Before the details, one key concept: a higher VLT percentage means lighter tint, and a lower VLT percentage means darker tint. So 25% is fairly dark, and anything below that number on the front would be illegal.
As of August 1, 2025, the front side window minimum is 25% VLT on all vehicles. This was a significant relaxation from the prior 40% limit, which had been among the stricter standards in the South. The back side windows must also meet 25% VLT. The rear window requires at least 12% VLT, which allows very dark tint while still permitting some light to pass through.
| Window | All Vehicles |
|---|---|
| Front side windows | 25% VLT minimum (eff. Aug 1, 2025) |
| Back side windows | 25% VLT minimum (eff. Aug 1, 2025) |
| Rear window | 12% VLT minimum |
Louisiana does not distinguish between sedans and multipurpose vehicles for VLT minimums. The same percentages apply to cars, SUVs, vans, and trucks on all windows.
2025 law change: what changed and when
Prior to August 1, 2025, Louisiana required front and back side windows to allow at least 40% of visible light through. That was one of the stricter front-window limits in the region.
2025 Act 143 (House Bill 119), signed into law and effective August 1, 2025, lowered the front and back side window minimum from 40% to 25%. The rear window minimum of 12% was not changed by the new law. If your vehicle has tint applied before that date that measured between 25% and 39%, it is now fully legal under the updated standard. Tint at or below 24% on the front or back side windows remains non-compliant.
Windshield tint rules in Louisiana
Louisiana permits a non-reflective tint strip on the top 5 inches of the windshield only. No tint of any kind is permitted in the main driving area below that strip. Red and amber tint colors are prohibited on the windshield strip regardless of where they fall on the glass.
Luminous reflectance is capped at 20% on all windows. This bans mirrored or metallic-finish films that could reflect light toward other drivers or law enforcement. The reflectivity limit applies to every window, including the rear, not just the front.
Red and amber colors are prohibited statewide on all windows, not just the windshield. Any film that produces a red or amber appearance, regardless of VLT level, violates Louisiana law.
Medical exemptions
Louisiana does allow a medical exemption for tint darker than the standard limits. The authority is La. R.S. 32:361.2. If you have a medical condition that requires protection from sunlight, such as lupus, photosensitivity, melanoma risk, or a related diagnosis, a physician must certify the need in writing.
The certification should describe the condition and the medical necessity for reduced light exposure. You must carry the physician documentation in the vehicle at all times. An officer who stops you for non-standard tint can review the paperwork on the spot.
If you cannot produce the documentation during the stop, you may receive a citation. Courts can consider the medical documentation later, but it is far simpler to keep it in the vehicle consistently.
How tint is measured and certified
Louisiana law enforcement uses a VLT meter to measure light transmission during traffic stops. The statute does not specify a published tolerance range, so installers generally recommend staying a few percentage points above the legal minimum as a buffer.
Louisiana requires an installer label of no more than 1.5 square inches, placed in the lower-right corner of the driver's window. The label identifies the installing dealer and confirms the film meets state requirements. Keep the label in place; its removal can raise questions about whether the film is compliant.
Ask your installer for a written receipt identifying the specific VLT of the film applied to each window. That documentation, kept in your glove box alongside the installer sticker, gives you a clear record if your tint is ever questioned.
Penalties for illegal tint in Louisiana
The penalty structure in Louisiana applies separately to operators and installers. For a vehicle operator, the fines are tiered: up to $150 for a first offense, up to $250 for a second, and up to $350 for a third or subsequent offense.
Installers face considerably higher exposure. A shop or technician who applies non-compliant film faces fines between $1,000 and $2,000 per violation. This elevated penalty reflects the legislature's intent to hold the commercial side of the tint industry accountable, not just drivers who may not have known their film was out of spec.
These fines apply to the darkness and color violations governed by La. R.S. 32:361.1. Medical exemption violations under La. R.S. 32:361.2 may be treated differently. If you have an exemption, producing that documentation can resolve a stop without a citation.
If you want to tint your windows in Louisiana
Under the current law (post August 1, 2025), you have meaningful flexibility. On the front side and back side windows, any film at 25% VLT or lighter is compliant. On the rear window, 12% VLT is the floor, allowing very dark tint. Many drivers choose 20% on the rear for maximum privacy while staying clearly within the law.
Choose a licensed Louisiana tint installer who will place the required compliance label in the lower-right corner of the driver's window. Ask for a written receipt listing the VLT on each window and store it in your vehicle.
Avoid red and amber films on any window. Even if the VLT is otherwise compliant, the color prohibition is a separate basis for a citation. If you have a qualifying medical condition, see your physician before installation so you have the La. R.S. 32:361.2 exemption documentation in hand before you drive.
If you have existing tint that was installed before August 1, 2025, check whether it was between 25% and 39% on the front and back side windows. If so, it is now legal under the updated standard and no action is required.
