Arizona's window tint rules depend on which windows you're tinting and what vehicle you drive
Arizona allows window tint on passenger cars, but the law sets specific darkness limits for different windows and requires you to meet those limits or face a citation. The front side windows must allow at least 33 percent of light through. The rear side windows and rear window can be any darkness. The windshield can have tint only on the top 4 inches, and that tint must allow at least 70 percent of light through. Vehicles registered as commercial trucks have different rules — they can tint rear windows and the rear window to any darkness, but front side windows still need the 33 percent minimum.
The darkness of tint is measured in Visible Light Transmission (VLT), which is the percentage of light that passes through the film. A 33 percent VLT tint blocks 67 percent of light. Arizona law does not require you to have your tint tested before installation, but law enforcement can measure it during a traffic stop or citation. If your tint is darker than the law allows, you can receive a citation and be ordered to remove it.
Key Takeaways
- Front side windows on passenger cars must allow at least 33 percent of light through; rear windows can be any darkness.
- The windshield can have tint only on the top 4 inches, and that section must allow at least 70 percent of light through.
- Commercial trucks have different rules and can tint front side windows more darkly than passenger cars, but the exact rules depend on the truck's registration class.
- Arizona law does not require pre-installation inspection, but officers can measure tint during a traffic stop and issue a citation if it exceeds legal limits.
- You can remove illegal tint yourself or have a shop remove it; the citation is typically dismissed once removal is documented.
Front side window tint limits for passenger vehicles
If you own a passenger car, sedan, SUV, or minivan registered in Arizona, your front side windows — the windows next to the driver and front passenger — must allow at least 33 percent of visible light to pass through. This is the strictest limit in the state. A tint that blocks more than 67 percent of light on these windows violates Arizona law, even if the tint is legal in another state.
The 33 percent rule exists because law enforcement and safety advocates argue that front side window tint can obstruct the driver's view and make it harder for officers to see inside the vehicle during a traffic stop. Arizona does not make exceptions for medical reasons or other circumstances — the 33 percent minimum applies to all passenger vehicles equally.
Rear and back window tint with no darkness limit
Arizona places no darkness limit on the rear side windows (behind the rear passengers) or the rear window (the back glass). You can tint these windows to any darkness, including limo tint or complete blackout, and remain within state law. This is one of the more permissive rules in the country and reflects Arizona's hot climate — darker rear tint helps keep the interior cool and protects rear passengers from sun exposure.
Many drivers use this rule to their advantage by tinting rear windows very darkly while keeping front windows at the legal 33 percent minimum. This approach keeps the cabin cooler while staying compliant with front-window rules.
Windshield tint rules and the 4-inch band
You can tint only the top 4 inches of your windshield, and that tinted section must allow at least 70 percent of light through. This means a windshield tint band must be relatively light — it blocks no more than 30 percent of light. The purpose of this rule is to preserve the driver's forward visibility while allowing some sun protection at the top of the windshield.
The 4-inch measurement is taken from the top of the windshield down. If your tint extends below 4 inches or is darker than 70 percent VLT, it violates state law. Some aftermarket sun shades that sit on top of the windshield are legal because they are removable and not permanent tint film, but permanent tint film must follow the 4-inch rule.
Commercial truck tint rules differ from passenger vehicles
Arizona law treats commercial trucks differently than passenger cars. A vehicle registered as a commercial truck can tint the rear side windows and rear window to any darkness, just like a passenger vehicle. However, the front side window rule is less clear for trucks, and the exact limit depends on the truck's specific registration class and whether it is classified as a light-duty or heavy-duty commercial vehicle.
If you own a truck, check your vehicle registration to confirm its classification. If you are unsure whether your truck qualifies as a commercial vehicle under Arizona law, contact your local Arizona Department of Transportation office or ask a tint shop — they work with these rules daily and can tell you what is legal for your specific vehicle. Misclassifying your truck as commercial when it is registered as a passenger vehicle can result in a citation.
What happens if your tint is too dark
If a law enforcement officer stops you and measures your tint with a light meter, they can issue a citation if the tint exceeds the legal darkness limit. The citation is typically a civil traffic violation, not a criminal charge. You will be ordered to remove the illegal tint within a set timeframe — usually 10 to 30 days, depending on the officer's citation and the local court's rules.
Once you remove the tint, you can request that the citation be dismissed by providing proof of removal to the court. Proof can be a receipt from a tint shop showing removal, a photo of the window after removal, or a statement from the shop. Some courts will dismiss the citation automatically once removal is documented; others require you to appear in traffic court or submit the proof by mail. Check the citation itself or contact the court listed on it to learn the specific process in your jurisdiction.
Removing illegal tint yourself or at a shop
You can remove window tint yourself using heat, a scraper, and rubbing alcohol, or you can have a professional tint shop remove it. Removal takes 30 minutes to 2 hours depending on how much tint you are removing and how well it was installed. If you remove it yourself, be careful not to scratch the window glass — use a plastic scraper rather than a metal one, and explore heat gradually to avoid thermal shock.
A tint shop will charge between $50 and $200 to remove tint from multiple windows, depending on how many windows and how stubborn the film is. This is usually faster and cleaner than a DIY removal. After removal, bring your vehicle to the officer who issued the citation or submit a photo and receipt to the court to show that you have complied with the removal order.
Frequently Asked Questions
Can I tint my windshield below the 4-inch line?
No. Arizona law allows tint only on the top 4 inches of the windshield, measured from the top edge down. Tint below that line violates state law, even if it is very light. The 4-inch limit is strict and does not have exceptions.
What if I have a medical condition that makes bright light painful?
Arizona law does not provide a medical exemption for window tint darkness limits. If you have a condition like photophobia, you may want to consult an eye doctor about other options, such as prescription sunglasses or a sun shade that sits on top of the windshield rather than permanent tint film. Some states do offer medical exemptions, but Arizona is not one of them.
Do I need to get my tint inspected before I have it installed?
No. Arizona does not require pre-installation inspection or certification. However, you are responsible for ensuring that the tint shop installs film that meets state limits. Ask the shop what VLT percentage they are installing and confirm it meets Arizona law for your vehicle type before they begin work.
Can I get a citation for tint that was legal when I installed it but the law changed?
Arizona's window tint law has remained stable for many years, so this is unlikely. However, if you move to Arizona from another state with different tint rules, your vehicle may not be compliant. You would need to have the tint adjusted or removed to meet Arizona limits.
What is the fine for illegal window tint?
The fine amount varies by county and court, but civil traffic violations for window tint typically range from $50 to $150, plus court costs. The main requirement is removal of the illegal tint within the timeframe stated on the citation. The fine is secondary to the removal order.
