Louisiana window tint laws require at least 25% visible light transmission on front side windows under Louisiana Revised Statutes Section 32:361.1. Rear side windows on cars need at least 25% VLT and the rear window needs at least 12% VLT. Sun screening devices may not exceed 20% luminous reflectance. Act 143 of 2025 lowered the front limit from 40% to 25% effective August 1 2025. This guide covers sedan and SUV rules, windshield limits, penalties, medical exemptions, and installer rules for Louisiana drivers.
Louisiana Window Tint Laws Overview
Louisiana regulates window tint through Louisiana Revised Statutes Section 32:361.1 as a sun screening device rule for registered vehicles. The law sets minimum light transmission percentages and a maximum reflectance cap for legal film on most passenger cars. Multipurpose passenger vehicles follow different rear window rules under the same statute.
Act 143 of 2025 amended the front side window standard during the 2025 regular session. House Bill 119 changed the minimum front side VLT from 40% to 25% with tolerances included in the measurement. The enrolled act was approved by the governor and took effect August 1 2025 per legislative records.
Drivers searching Louisiana tint laws in 2026 should use the 25% front rule rather than older 40% guides still online. Laws and enforcement may change. Check official Louisiana sources for the latest rules.
Key Terms Drivers Should Know
Light transmission is the VLT percentage Louisiana uses for window tint laws. It measures how much total light passes through the film and the glass together. A lower VLT number means darker tint because less outside light enters the cabin.
Luminous reflectance measures how much light the sun screening device reflects outward from the vehicle. Louisiana Revised Statutes Section 32:361.1 caps luminous reflectance at 20% for all legal sun screening devices on covered windows.
A sun screening device means film or material designed to reduce sun effects when used with automotive safety glazing. Louisiana law defines distributor installer manufacturer and seller roles in Section 32:361.1 subsection A for enforcement and business penalties.
Legal Tint Limits for Sedans and Coupes
Louisiana window tint VLT rules for standard passenger cars require minimum light transmission on three window groups. Front side windows need at least 25% VLT with all tolerances included. Rear side windows behind the driver on sedans need at least 25% VLT on the same standard.
The rearmost window on a sedan or coupe must allow at least 12% VLT under Louisiana Revised Statutes Section 32:361.1 subsection C paragraph 1. That 12% rear window rule is the darkest legal limit the statute sets for a standard car rear glass.
| Window Position | Sedan Minimum VLT | | Front Side Windows | 25% | | Rear Side Windows | 25% | | Rear Window | 12% | | Max Reflectance | 20% |
Illegal window tint on a registered Louisiana sedan may result in fines under subsection E of the same statute. Combined film and glass readings matter because the law includes all tolerances in the VLT test.
Tint Rules for SUVs Trucks and Multipurpose Vehicles
Louisiana tint laws treat multipurpose passenger vehicles differently from sedans on windows behind the driver. The light transmittance requirement does not apply to rear side windows or the rear window on trucks buses trailers motor homes and multipurpose passenger vehicles.
Front side windows on an SUV still need at least 25% VLT under the same 2025 standard that applies to sedans. That means Louisiana legal tint percentage Louisiana drivers see online for SUVs often mixes two rules in one chart.
SUV tint Louisiana rear windows may use any darkness because no VLT floor applies to those positions on qualifying vehicle types. The statute lists multipurpose passenger vehicles alongside trucks and motor homes in subsection C paragraph 4.
Windshield Tint Rules in Louisiana
Windshield tint Louisiana rules allow a narrow strip at the top of the glass only. Louisiana Revised Statutes Section 32:361.1 subsection C paragraph 2 permits transparent material that is not red or amber on the topmost windshield portion.
The strip may not extend more than five inches down from the top of the windshield. Material on the front windshield or front side windows may not obstruct or reduce the driver clear view under subsection B.
Can you tint windshield in Louisiana beyond that strip? General full windshield tint that reduces light transmission or alters color on the main viewing area is not allowed outside the statutory exceptions. Non adjustable factory sun visors mounted forward of the side windows remain exempt.
Reflectance and Film Rules
Louisiana window tint laws cap luminous reflectance at 20% for every sun screening device used under the legal VLT standards. Reflectivity above that level violates the same statute even when VLT percentages otherwise comply.
Dark tint Louisiana legal limits depend on VLT not on shade name alone. A 5 percent film on a rear sedan window fails the 12% rear rule even if the product label sounds compliant for other states.
The darkest legal tint in Louisiana on front side glass is 25% VLT after the 2025 law change. Rear sedan glass may go to 12% VLT on the rearmost window only. SUVs may use darker rear tint with no statutory floor behind the driver.
Certification Labeling and Installer Requirements
Louisiana tint installer label rules require permanent labeling on tinted glass. Each installer must place a label not over one and one half square inches between the film and the glazing surface under subsection D.
The label must show the installer name and city where the business operates. Louisiana law requires placement on the lower right corner of the driver side window for legible inspection during traffic stops.
Manufacturers must certify sun screening devices to the Department of Public Safety and Corrections office of motor vehicles using independent laboratory data per subsection D paragraph 1. Sellers installers manufacturers and distributors face separate business fines under subsection G for violations.
Penalties for Illegal Window Tint
Louisiana window tint penalty rules set rising fines for drivers of state registered vehicles. A first offense may bring a fine up to $150 under Louisiana Revised Statutes Section 32:361.1 subsection E.
A second offense may bring a fine up to $250 and a third or later offense may bring a fine up to $350. Those amounts come from the official statute text rather than secondary news summaries.
Louisiana tint ticket cost for businesses differs sharply from driver fines. A seller installer manufacturer or distributor may face a $1000 fine on a first business offense and $2000 on a second offense. A third business conviction may bar further operations under subsection G.
Medical Exemption for Window Tint
Louisiana window tint medical exemption rules appear in Louisiana Revised Statutes Section 32:361.2. The standard VLT and reflectance limits in Section 32:361.1 do not apply when a qualifying medical affidavit is in the vehicle.
A licensed optometrist or physician in Louisiana must sign an affidavit stating a sun related medical condition requires darker sun screening material. A copy of the affidavit must stay in the vehicle at all times per subsection A.
The Department of Public Safety and Corrections issues a decal for each medically exempt vehicle under subsection E. The decal must stay prominently displayed to show tinted windows relate to an approved medical issue.
Photophobia claims require extra physician explanation on why sunglasses cannot provide enough protection and why tint will not block safe night driving. New owners of sold exempt vehicles must remove tint or obtain a new exemption.
Exceptions and Special Cases
Louisiana tint laws exempt publicly owned law enforcement vehicles and Department of Wildlife and Fisheries enforcement vehicles under subsection C paragraph 4. Private law enforcement window treatment follows separate statutory language in the same section.
Vehicles with tint applied on or before December 31 1993 may qualify for a certificate exemption under subsection I. The owner must carry the office of motor vehicles certificate proving pre 1994 tint when an officer requests it.
Louisiana front window tint law 2025 change does not alter the rear 12% sedan rule or the 20% reflectance cap. It only lowers the front side minimum from 40% to 25% under Act 143 of 2025.
Common Misconceptions About Louisiana Tint Law
Many guides still list 40% VLT on front side windows without noting Act 143 of 2025. Louisiana window tint laws now use 25% on front side glass for all covered vehicle types since August 1 2025.
Some sites cite an AS-1 windshield line though Louisiana Revised Statutes Section 32:361.1 names a five inch top strip limit instead. Drivers should rely on the state statute wording for windshield tint Louisiana compliance.
Another myth says all vehicles share sedan rear limits. Multipurpose passenger vehicle owners may legally use any rear darkness behind the driver while front side 25% VLT still applies.
Louisiana drivers comparing state rules may also read Maine window tint laws for northeast limits while reviewing Gulf South standards. Consult a licensed attorney in Louisiana for questions about a specific ticket or medical waiver application.
