Arizona window tint laws set a 33% VLT minimum for front side windows. Rear side and rear windows have no darkness limit. Reflectivity is capped at 35% on side and rear windows. This article covers the tolerance rule penalties exemptions and windshield limits. All rules are drawn from Arizona Revised Statutes Section 28-959.01.
Key Terms Drivers Need to Know
VLT stands for Visible Light Transmission. It is the percentage of light passing through combined glass and film. Higher VLT means lighter tint. Lower VLT means darker tint. Under Arizona law 33% VLT allows one-third of daylight through front windows.
The AS-1 line is a marking etched near the top edge of the windshield. It sits within the first few inches of glass closest to the roof frame. Arizona law allows non reflective tint only above this line on the windshield. Tint may not extend below the AS-1 line. Drivers locate it by checking the upper windshield edge near the headliner.
Luminous reflectance measures how much light bounces off tinted glass toward other drivers. Arizona caps reflectivity at 35% on side and rear windows. High reflectivity creates glare and reduces safety for oncoming drivers. This cap applies independently from the VLT requirement. A film meeting VLT rules can still violate the law if reflectance exceeds 35%.
What the Arizona Statute Says
Arizona Revised Statutes Section 28-959.01 is the governing law for window tint in Arizona. It was confirmed effective through the 57th Legislature 1st Regular Session. FindLaw confirms the text as current through January 1 2025. The statute covers VLT minimums reflectivity limits color rules and the exemption process. Drivers should verify current status at azleg.gov before making changes.
Subsection A sets the 33% VLT rule for front side windows and wing vents. That same subsection includes a tolerance of plus or minus 3%. The law does not treat 33% as a hard cutoff. A reading of 30% on a calibrated meter may fall within the legal range. Many shops install 35% film on front windows to stay inside the tolerance.
The 3% tolerance is written into the statute but rarely explained. Law enforcement tint meters carry their own accuracy range. A reading near the 33% line does not automatically produce a citation. The statutory tolerance remains in effect regardless of the meter reading. Drivers contesting a marginal reading should reference the tolerance language in Section 28-959.01.
Arizona VLT and Reflectivity Rules
Section 28-959.01 applies different rules to each window location. The windshield may carry only non reflective tint above the AS-1 line. Front side windows and wing vents must allow at least 33% VLT. The plus or minus 3% tolerance applies to that 33% minimum. No VLT minimum applies to rear side windows or the rear window.
Rear side windows and the rear window carry no darkness restriction under Arizona law. A driver may apply any level of film darkness to those windows. However the 35% reflectivity cap still applies to those windows. Tinting the rear window also triggers the dual mirror requirement below. These rules apply equally to passenger cars and to multi purpose vehicles.
Who Arizona Tint Rules Apply To
Arizona applies the same 33% front window VLT rule to all vehicle types. Passenger sedans SUVs vans minivans and pickups follow identical front window rules. Many states give SUVs or vans looser VLT allowances. Arizona does not make that distinction. The uniform rule comes directly from Section 28-959.01.
Commercial vehicles may operate under different standards. The statute governs privately operated passenger and multi purpose vehicles. Drivers of commercial vehicles should confirm applicable rules with ADOT. Government vehicles may follow separate guidelines. This article covers privately operated vehicles only.
Tint Color Restrictions
Arizona law bans red and amber tint on any vehicle window. These colors mimic traffic signal colors and create confusion for other drivers. All other colors are permitted if VLT and reflectivity limits are satisfied. A blue or green film on front windows must still allow at least 33% VLT. Color compliance and VLT compliance are both required independently.
The statute prohibits any material that reduces light transmittance in violation of the VLT rules. An extreme opaque film on front windows violates the law if it drops below 33%. A film does not need to be labeled red or amber to cause a violation. Meeting color rules does not exempt a film from VLT or reflectivity requirements. Both standards must be satisfied simultaneously.
Reflectivity Rules in Detail
The 35% reflectivity cap applies to front side rear side and rear windows. The windshield faces a stricter standard: reflective tint is banned entirely on the windshield. Only non reflective material may appear above the AS-1 line. No reflectivity tolerance exists for the windshield under the statute. Any mirror-like or metallic film on the windshield violates the law.
Reflectivity is measured separately from VLT by a tint meter. A film that passes the VLT check can still generate a citation. That happens when reflectance exceeds 35% even with a legal VLT reading. Drivers purchasing metallic films should confirm the reflectance rating from manufacturer spec sheets. Choosing a film with reflectance well below 35% provides additional clearance.
Rear Window Tinting and the Dual Mirror Rule
Rear side windows and the rear window carry no VLT minimum in Arizona. A driver may apply 5% or any darkness level to those windows. However tinting the rear window triggers a separate legal requirement. Two functioning exterior side mirrors are required whenever any rear window tint is installed. One mirror must sit on the driver side and one on the passenger side.
A vehicle with a tinted rear window and only one exterior mirror violates Arizona law. This is a separate equipment offense from any VLT violation. Law enforcement may cite both infractions on the same traffic stop. Vehicles with one factory side mirror need a second mirror added before rear window tint. The dual mirror rule applies regardless of how dark the rear window tint is.
Factory Privacy Glass and Combined VLT
Factory privacy glass is dark tinted glass installed during vehicle manufacture. It reduces light transmittance before any aftermarket film is applied. Many SUVs vans and trucks include factory privacy glass on rear windows. An officer tint meter reads the combined transmittance of glass and added film. This combined reading is not the same value printed on the film package.
Adding 35% VLT film to factory privacy glass produces a lower combined reading. On rear windows that creates no violation because no VLT minimum applies there. However adding 35% film to factory tinted front side glass can cause a violation. The combined front window reading may drop below 30% and fall outside the statutory tolerance. Drivers should measure existing front glass VLT before adding any aftermarket film.
A shop measuring only the film VLT is not providing a complete compliance check. The statute does not exempt a driver because the installer failed to measure correctly. Responsibility for front window compliance rests with the vehicle operator. Buyers of used vehicles should have front window combined VLT measured early. A combined reading below 30% on front windows likely falls outside the statutory tolerance.
Penalties for Illegal Window Tint
Arizona primarily addresses illegal window tint through an Equipment Repair Order. This is the state version of a fix-it ticket rather than an immediate fine. An officer issues the order and the driver must correct the violation. A shop receipt showing tint removal or replacement serves as proof of correction. Bringing that proof to court often results in dismissal.
Monetary fines apply when drivers fail to correct the violation in time. Available sources report fines ranging from approximately $100 to $250. Fine amounts vary by court and by county across Arizona. The statute does not set a single fixed statewide fine amount. Drivers facing a court proceeding may wish to consult a licensed attorney.
The Equipment Repair Order process does not guarantee dismissal in all cases. Reinspection showing a continuing violation may result in a monetary penalty. Some officers issue monetary citations directly for clear violations. A Glendale PD sergeant confirmed the repair order process to AZCentral in August 2025. Fine amounts may change and drivers should verify current penalty ranges with their court.
Medical Exemptions for Window Tint
Section 28-959.01 subsection G authorizes a medical exemption for darker than standard window tint. The exemption covers vehicles owned by or regularly used to transport the applicant. Qualifying conditions may include lupus xeroderma pigmentosum photosensitivity photophobia and glaucoma. Other conditions include porphyria dermatomyositis skin cancer and severe sun allergies. The exemption requires physician certification and ADOT approval before it takes effect.
Qualifying Physicians
A certifying physician must hold a license under Arizona Revised Statutes Title 32. The relevant chapters are Chapter 13 Chapter 14 and Chapter 17. Those chapters cover MDs DOs NMDs and ophthalmologists. A chiropractor or nurse practitioner does not qualify as a certifying physician under the statute. The physician must attest in writing that the applicant requires protection from sunlight exposure.
How to Apply
The applicant must complete ADOT Form 40-1511 Application for Window Tint Medical Exemption. The form carries a May 2026 revision date and is available on the ADOT website. After obtaining physician certification the form goes to the ADOT Medical Review Program. Contact details for the Medical Review Program are listed on the ADOT site. The driver must carry the approved exemption certificate in each covered vehicle at all times.
Scope of the Exemption
The medical exemption covers driver side passenger side and rear side and rear windows. It does not cover the windshield below the AS-1 line. No exemption permits darker tint on the windshield below that marking. The exemption applies to regular passengers of a vehicle as well as the driver. The certificate must remain in the vehicle whenever darker than standard tint is installed.
No Sticker or Label Required
Arizona law does not require a compliance sticker or label on a tinted window. Many states mandate a window sticker listing the film VLT and manufacturer certification. Arizona has no such requirement for vehicle operators. The statute places a certification duty on film manufacturers under Section 28-959.01 subsection D. Manufacturers must certify their products to the ADOT director.
That manufacturer certification does not protect the driver from a citation. A manufacturer certificate is not a defense against a VLT violation. Sellers and installers must warn that front window tint may be illegal in some states. That warning does not shift compliance responsibility from the driver to the seller. The vehicle operator remains responsible for front window VLT compliance in Arizona.
Common Misconceptions About Arizona Tint
A driver who buys a vehicle with illegal tint must bring it into compliance. Arizona law places that responsibility on the vehicle operator not the prior owner. A receipt showing another party installed the tint is not a legal defense. Buyers of used vehicles should have all front window tint measured promptly. A combined front window VLT below 30% likely falls outside the statutory tolerance.
Many drivers believe a tint shop install guarantees legal compliance. Arizona law does not support that assumption. A seller must warn that film may be illegal on front windows in some states. That warning does not transfer responsibility from driver to shop. The driver operating the vehicle on Arizona roads bears responsibility for any resulting violation.
A common myth holds that SUVs and trucks can have darker front windows than sedans. The statute applies the same 33% VLT minimum to all vehicle types. Officers read combined glass and film transmittance not the film label. Tint rules differ across state lines and drivers should confirm local rules before traveling. Drivers can review Arkansas window tint laws for a neighboring state comparison.
