Louisiana Window Tint Laws 2026

Louisiana requires 25% VLT on front side windows, down from 40% as of August 1, 2025. On a sedan, the side windows behind the driver also need 25%, and the rear-most window needs 12%. Trucks, buses, motor homes, and multipurpose vehicles, the SUV category, are genuinely exempt behind the driver, this is one of the few states where that widely repeated claim is actually accurate.

Quick Reference

The 2025 Change: What Actually Happened

House Bill 119 of the 2025 Regular Session, enacted as Act 143, amended R.S. 32:361.1(C)(1) to reduce the front side window minimum from 40% VLT to 25% VLT. It took effect August 1, 2025. Louisiana had been one of the stricter front-window states in the South at 40%, and this change moved it into the same range as Texas, Arkansas, and Oklahoma at 25%. The bill only touched the front side window figure, the 12% rear-most window standard was unchanged.

A practical consequence: tint installed before August 1, 2025 that measured between 25% and 39% was technically non-compliant at the time but is fully legal under the current standard. Tint at or below 24% on the front or back side windows remains a violation regardless of when it was installed.

Where the Vehicle-Type Split Is Real

R.S. 32:361.1(C)(4) states plainly that the light transmittance requirement of the section does not apply to windows behind the driver on trucks, buses, trailers, motor homes, and multipurpose passenger vehicles, and to all windows on vehicles used for law enforcement purposes. Unlike several other states where this claim turns out to be an urban legend or a misreading of a factory-glass exemption, Louisiana's statute says it directly. That exemption covers both the side windows behind the driver and the rear-most window for the listed vehicle types.

A standard passenger car doesn't get this exemption. Sedan side windows behind the driver still need 25%, and the rear-most window still needs 12%.

Legal vs Illegal

Two Separate Exemptions: Medical and Security

Medical exemption

The medical exemption isn't a subsection of the main tint statute, it's its own law, R.S. 32:361.2, and it's considerably more detailed than a simple physician's note. It requires a signed affidavit from an optometrist or physician, including but not limited to an ophthalmologist or dermatologist, licensed in Louisiana, stating the applicant has a condition involving the effects of the sun. The affidavit itself is prepared by Louisiana State Police and lists the World Health Organization ICD-9-CM recognized conditions that qualify, with a section for a provider to describe a condition not already on that list. LSP may refer a borderline case to the Louisiana Medical Advisory Board before deciding.

A few details worth knowing before applying: the exemption is non-transferable, expires three years after issuance, and covers the registered owner, their spouse, or a family member authorized to operate the vehicle, not just the titleholder. One exception to the three-year expiration: an exemption granted for diagnosed light-sensitive porphyria is valid for as long as the person owns the vehicle, no renewal required. People convicted of a violent crime or drug offense are not eligible for the exemption at all. The official LSP affidavit also permits windshield tint to extend 6 inches down from the top for an approved holder, a larger allowance than the standard 5-inch strip everyone else gets.

The security exemption, a separate legal path

This is a genuinely distinct provision most tint guides don't mention at all. R.S. 32:361.3 lets a vehicle owner apply for an affidavit through the Department of Public Safety and Corrections when valid security reasons make darker tint necessary, independent of any medical condition. The affidavit describes the specific vehicle and must be kept inside it. This gives Louisiana two separate, named legal pathways to an exemption where most states only have one.

Penalties, and Shops Face a Much Steeper Track

A driver caught with illegal tint under R.S. 32:361.1(E) faces a fine of not more than $150 for a first offense, $250 for a second, and $350 for a third or subsequent offense.

Sellers, installers, manufacturers, and distributors face a separate and considerably steeper penalty under subsection (G): a fine of $1,000 for a first offense and $2,000 for a second, with the added consequence that a second violation can result in being prohibited from conducting that business at all. Louisiana treats the professional side of illegal tint as a much more serious problem than an individual driver's violation.

Enforcement

Tint is a primary offense in Louisiana. State Police and local departments use a VLT meter to measure light transmission during a stop. The statute doesn't publish a specific measurement tolerance, so most installers recommend staying a few points above the legal minimum as a practical buffer.

What Legal Tint Actually Costs in Louisiana

Since sedan owners now have real room on the front at 25%, and unlimited darkness remains off the table behind the driver except on the rear-most window at 12%, a common setup pairs a compliant front with a much darker rear-most window. SUV and truck owners have full freedom on everything behind the driver. Ceramic film is a common upgrade for UV and infrared rejection given Louisiana's heat and humidity.
