California Window Tint Law 2026: What’s Legal in Orange County?

Under California Vehicle Code §26708, the front side windows can take only clear, colorless film. The film has to let at least 88% of visible light through on its own, and the window has to measure at least 70% with the film on. The windshield can only take a thin strip along the top. Back side windows have no darkness limit, and neither does the rear window if the car has mirrors on both sides. Medical exemptions are narrow, and none of them allows tinted film up front.

Below is the OC-driver version: the table, how to clear a tint ticket, how the medical exemption actually works, and how to get real heat rejection without breaking the code.

California VLT limits at a glance

VLT is the percentage of visible light that passes through the glass and film combined. Higher number = lighter tint.

California doesn’t split the rules by vehicle class the way some other states do. A Camry and a Suburban get the same front-side rule.

One thing that trips people up: California checks two numbers on the front sides. The film itself has to be clear and rated 88% VLT or higher. That’s the legal minimum, not a rule of thumb. Then the window, glass and film together, still has to measure at least 70%. The film also has to block UV, and the law says to keep the installer’s certificate in the car, so ask for it. If a shop tells you they can put 70%, 35%, or 20% on your front doors and it’ll pass, they’re wrong.

What VLT actually means

VLT is short for Visible Light Transmission. It’s a single number that tells you how much light makes it through the glass. 70% VLT means 70% of the light gets through and 30% is blocked. 5% VLT, often called “limo tint,” blocks 95%.

CHP officers use a handheld tint meter that reads VLT off both windows at once (glass plus film). If your front sides come back below 70%, you’re out of compliance no matter what the film box said. And a tinted film up front is out of compliance even if the meter reads 70%, because the film itself has to be clear and rated 88% or higher.

Is 5% tint legal in California?

Only on the rear side windows, and on the back window if the car has mirrors on both sides. Never on the front sides or windshield. A limo-dark 5% film on your driver’s window will fail a CHP tint meter reading every time, and there’s no exemption path that opens up that darkness on the front. A medical letter doesn’t change that, because no California medical exemption allows tinted film on the front sides.

Got a VC 26708(a)(1) ticket? How to clear a tint fix-it ticket

If your ticket lists VC 26708(a)(1), here’s what it means. That subsection says no one may drive with “any object or material placed, displayed, installed, affixed, or applied upon the windshield or side or rear windows.” Window film is material applied to the glass, so it’s covered unless one of the section’s exceptions applies. Those exceptions are what make legal tint legal: any darkness on the rear side windows, the rear window if you have mirrors on both sides, a strip across the top of the windshield, clear 88% film on the front side windows, and clear UV film on any window with a dermatologist’s certificate. A 35% film on the driver’s window falls outside all of them.

The base fine is $25, but court fees and assessments stack on top, so the total on the citation is often close to $200, depending on the county. The total on the ticket is what matters.

Not every tint ticket is a correctable violation, the kind most people call a fix-it ticket. Under VC 40610, a notice to correct isn’t used if the officer finds fraud or persistent neglect, an immediate safety hazard, or a driver who won’t or can’t fix the problem promptly. If yours was written as correctable, you can clear it by fixing the car and proving it. If it wasn’t, or you can’t tell, call the court listed on the ticket or talk to a traffic lawyer. We can tell you what the code says and fix the glass. We can’t tell you how to handle your case.

How to clear a tint fix-it ticket, step by step

1. Read the ticket. Note the court, the due date, and the code section it cites.
2. Fix the windows. Take off the film the ticket covers. The front side windows can stay bare, or they can take clear film that lets in at least 88% of light on its own, blocks UVA, and leaves the window at 70% or better. If you go with clear film, keep the installer’s certificate in the car.
3. Get the correction signed. A police department, the CHP, a sheriff, a marshal, or another agency that enforces the Vehicle Code can sign the certificate of correction on the back of the ticket (VC 40616). In Orange County, the court says sheriff’s deputies inspect cars at every justice center except the Central Justice Center in Santa Ana, and the sheriff charges $15 for the sign-off.
4. Send the court your proof and the fee by the due date. The clerk collects a $25 transaction fee for each corrected violation (VC 40611). In Orange County, you can upload proof of correction through the court’s My Court Portal. If you mail it, the court says to allow 10 days for delivery and processing.

Don’t let the date slide. Under VC 40616, willfully breaking the promise to correct, or willfully failing to deliver proof, is a misdemeanor.

If the tint was on the car when you bought it (dealer add-on, prior owner), you’re still the one who has to fix it. The code doesn’t care who installed it.

We take off old film in-house at our Costa Mesa shop, and we can put clear ceramic film back on the front side windows if you want heat and UV protection that’s legal. Call (949) 642-1121, or request an automotive quote.

Medical exemptions (Vehicle Code §26708 and §26708.2)

California has two medical exemptions for drivers and passengers with a condition that makes sun exposure a real health problem, like lupus or severe photosensitivity. Both are narrower than most people think.

Physician or optometrist letter. With a signed letter from a licensed physician or optometrist, you can use a removable sun shade on the front side windows, like a roller shade or a framed screen. If it’s see-through, it has to be green, gray, or neutral smoke and let in at least 35% of light. It can’t be film stuck to the glass, and it can’t be used after dark. Section 26708 doesn’t call for a DMV form. Keep the letter on you, not just in the car: the statute says the person it covers has to have it in their possession.

Dermatologist certificate. With a certificate from a licensed dermatologist, you can put clear, colorless UV-blocking film, rated 88% or higher, on any window, including the windshield. It doesn’t allow tinted film. Clear 88% film is already legal on the front sides without it, so the windshield is where the certificate matters.

Neither exemption lets you put 35%, 20%, or 5% film on the front side windows. If a shop offers to do it with a doctor’s note, you can still get a ticket for the film.

Reflective, colored, and factory tint

A few more things to know, even when your VLT numbers are fine:

• Mirror or reflective tint. Front side film has to be clear and colorless, so mirrored film is out up front. The windshield strip can’t reflect more glare than the bare glass.
• Colored tint. The windshield strip can’t be red or amber, and front side film has to be colorless. Charcoal, gray, and bronze are all fine in the back.
• Factory-tinted rear glass. If your car came from the factory with dark rear glass (common on SUVs), that’s legal on its own. Adding film on top is fine too. If you want the car to look even, match your ceramic to the factory shade.

How OC drivers stay compliant and still get real heat rejection

Living in Orange County, the reason most drivers want tint isn’t the look. It’s the heat coming off the 405 at 3 p.m. in July. The good news: a clear ceramic film on the front sides blocks UV and a good share of infrared heat while staying inside the law, and you can go as dark as you like in the back. You don’t need a dark film to get a cool cabin. You need the right chemistry. Our Orange County tint cost guide breaks down what a legal, high-IR ceramic install actually runs by film tier, and our Irvine shop page has same-week appointments. Not sure which installer to trust with the job? Our guide to choosing a window tint shop in Orange County covers the certifications and questions that separate a quality install from a bargain one. (Homes and businesses have their own rulebook. Residential window tinting doesn’t share the auto VLT limits.)

Frequently asked questions

What is the darkest legal tint in California? On the front side windows, no tinted film is legal. You can add clear film rated 88% or higher, as long as the window still measures at least 70% with it on. Back side windows have no darkness limit, and neither does the rear window if the car has mirrors on both sides, so you can run 5% back there.

Is 20% tint legal on front windows in California? No. Front side windows can only take clear film rated 88% or higher. 20% is fine on back side windows and the rear glass, but never on the driver or front passenger window.

Can you tint the windshield in California? Only a non-reflective strip along the top, and its bottom edge has to sit at least 29 inches above the driver’s seat. It can’t be red or amber. Below that line, the windshield stays clear. The one exception is clear UV film rated 88% or higher, which a licensed dermatologist can certify you for.

How much is a window tint ticket in California? The base fine for a VC 26708 violation is $25, but court fees and assessments bring the total on the ticket close to $200, depending on the county. If the ticket was written as a correctable violation, you can fix the windows, get the correction signed, and send proof to the court by the due date instead. The court charges a $25 transaction fee for each corrected violation.

Do you need to remove the tint to fix a ticket? Yes. You have to bring the car back into compliance. That usually means peeling the front-side film and either leaving the glass bare or putting on clear ceramic film that lets in at least 88% of light on its own.

What violation is VC 26708(a)(1)? It’s the Vehicle Code subsection that bars driving with any object or material on the windshield or side or rear windows. Window film counts unless an exception covers it: the rear side windows, the rear window with mirrors on both sides, a strip across the top of the windshield, clear 88% film on the front side windows, and clear UV film on any window with a dermatologist’s certificate. Tinted film on the front side windows is a 26708(a)(1) violation.

How do I clear a window tint fix-it ticket? Remove the film the ticket covers, have a police department, the CHP, a sheriff, or a marshal sign the certificate of correction on the back, and send the signed ticket to the court with the $25 transaction fee by the due date. This works only if the ticket was written as a correctable violation.

Does a medical exemption let me put 5% tint on my front windows? No. A doctor’s letter allows a removable sun shade up front, not 5% film. The shade has to let in at least 35% of light, and it has to come down after dark. No California medical exemption allows tinted film on the front side windows.

Are ceramic tints legal in California? Yes. On the front sides, the ceramic film has to be clear and let in at least 88% of light on its own, and the window has to measure at least 70% with it on. In the back, any darkness works. The rear window just needs outside mirrors on both sides. Ceramic just describes the material and how it filters heat. It doesn’t change the darkness math.

Is factory tint on my SUV legal? Yes. Factory-privacy glass on back side and rear windows is legal on its own. You can add film on top, too. If you want it to match, keep the added film neutral.

Do I need dual side mirrors if my rear window is tinted? Yes. If the rear window is tinted, California requires functioning driver-side and passenger-side mirrors. Most modern cars have those already.

Can Orange County police pull me over just for tint? Yes. Tint is a standalone stop under Vehicle Code §26708.

Does factory tint count toward the legal VLT limit? Yes, for the 70% test. That test measures the window with the film on, so the factory glass counts. The film has its own test too: it has to be clear and let in at least 88% of light on its own. They’re separate rules, and front-side film has to pass both.

Is reflective tint legal in California? Not up front. Front side film has to be clear and colorless, which rules out mirrored film, and the windshield strip can’t reflect more glare than the glass itself.

Will window tint affect a smog check or vehicle registration in California? No. Window tint isn’t checked during California smog inspections. It can still get you a fix-it ticket during a regular traffic stop, though, which requires you to remove or replace the illegal film and submit proof of correction.

What happens if I buy a car with illegal tint already on it? You’re responsible for the car’s compliance no matter who installed the tint. If you buy a vehicle with illegal front-window tint, you’ll need to have it removed or replaced with a legal film to avoid a citation.
