Arizona is known for its intense sunlight and high temperatures. For many drivers, window tint helps reduce glare, improve comfort, and keep vehicles cooler during long drives. However, Arizona law regulates how dark vehicle windows can be tinted. Drivers who exceed those limits without authorization may receive citations.
For individuals who have medical conditions that make sunlight exposure harmful, Arizona provides a legal solution through a Arizona window tint exemption. This exemption allows darker window tint when a licensed physician confirms that protection from direct sunlight is medically necessary.
Understanding how the exemption process works can help drivers obtain the proper documentation while staying compliant with Arizona law.
Understanding Arizona Window Tint Laws
Before exploring the exemption process, it is important to understand Arizona’s standard window tint limits.
Under Arizona tint laws, front side windows must allow more than 33 percent of visible light to pass through the glass. This is referred to as visible light transmission, or VLT. Rear side windows may be darker but must still follow state reflectivity limits. The rear window can also have darker tint as long as it complies with the same reflectivity standards. Arizona also restricts tint on the windshield. Tint is only permitted above the AS-1 line or the manufacturer’s designated strip at the top of the windshield. If a driver installs tint darker than these limits without a valid exemption, they may receive a citation during a traffic stop.

When a Medical Tint Exemption May Be Needed
Some individuals experience medical conditions that make exposure to sunlight painful or dangerous. These conditions often involve extreme sensitivity to ultraviolet light, visible light, or heat. Arizona law recognizes this issue and allows individuals to request an Arizona medical window tint exemption when protection from direct sunlight is medically necessary.
For these drivers, darker window tint can help reduce glare and limit harmful exposure to sunlight while driving. However, the exemption must be approved through a formal process before darker tint can be installed legally.
Step 1: Obtain Physician Certification
The first step in the Arizona tint exemption process is obtaining certification from a licensed physician. Arizona law requires written medical attestation confirming that the patient must be shielded from direct sunlight for medical reasons. This certification must be completed by a physician licensed under Arizona medical regulations. During the evaluation, the physician reviews the patient’s symptoms and determines whether darker window tint is medically appropriate. If the physician confirms the need for sun protection, they complete the medical certification section of the Application for Window Tint Medical Exemption.
Step 2: Complete the Application
After the physician completes the medical portion of the exemption application, the patient must complete the remaining sections of the form. The application requires personal identifying information and vehicle details. This information helps the Arizona Department of Transportation process the exemption request and issue the certificate to the correct individual. It is important that the application is completed accurately to avoid delays during the review process.
Step 3: Submit the Application to the State
Once the application is complete, it must be submitted to the Arizona Department of Transportation for review. Arizona requires that the completed exemption application be sent to the department’s Medical Review Program. The state reviews the documentation to ensure that the medical certification and application information meet the legal requirements. If the application is approved, the state issues a certificate of medical exemption.
Step 4: Keep the Certificate in Your Vehicle
After approval, Arizona requires that the exemption certificate be signed and displayed on the vehicle dashboard. This certificate serves as proof that the darker window tint is authorized under Arizona law. If a driver is stopped by law enforcement, the certificate allows officers to verify that the tint is legally permitted. Failing to keep the certificate in the vehicle may result in confusion during a traffic stop, even if the exemption was approved.

Medical Conditions That May Qualify
Drivers often pursue a legal tint exemption in Arizona because they experience severe sensitivity to sunlight. While every case is reviewed individually by a physician, several medical conditions may qualify for an exemption.
Examples include:
- Lupus
- Photosensitivity disorders
- Albinism
- Skin conditions aggravated by sunlight
- Severe migraines triggered by bright light
- Solar urticaria
- Certain eye disorders requiring reduced light exposure
A physician evaluation determines whether a patient is qualifying for a tint exemption in Arizona.
Why Many Drivers Research the Process Online
Because the exemption process involves physician certification and state review, many drivers research the process online before getting started.
Drivers often want to understand the documentation requirements, how physician certification works, and what steps are involved in receiving approval.
Learning these details in advance can help drivers complete the process correctly and avoid delays.
The Role of Physician Consultation Services
Some drivers choose to use services that connect them with licensed physicians who understand the documentation requirements for tint exemptions.
These services can help determine whether a medical condition qualifies for an Arizona medical window tint exemption. If approved, the physician completes the certification required for the exemption application.
After that step, the driver submits the completed application to the Arizona Department of Transportation for final review. Because the state ultimately approves the exemption, following the correct application process remains essential.
