  • Dual side mirrors are required if the rear window is tinted
  • Front-window medical relief is limited to removable daytime sunscreens or clear UV film
  • Most tint tickets are correctable fix-it tickets

Tint limits by window

Percentages are the minimum VLT allowed. A lower number is a darker tint.

How California compares

California allows 70% VLT on the front side windows of a car. That is darker than 3 states allow and lighter than 41 states permit, and 5 other states use the same limit. If you want to see what 70% VLT actually looks like on glass, compare it in our tint percentage examples.

California borders Arizona, Nevada and Oregon. None of its neighbors are stricter about front windows, so legal California tint is legal next door too. Shops in Arizona, Nevada and Oregon can legally install darker film than California allows, so check the meter reading if you tint across the border. Our guide to crossing state lines with tinted windows explains how out-of-state cars are treated.

Sedans vs SUVs, trucks and vans

California uses the same limits for every vehicle type: 70% VLT on the front side windows, any darkness on the back side windows and any darkness on the rear window, whether you drive a sedan, SUV, pickup or van.

Many SUVs and trucks leave the factory with dark privacy glass behind the driver. Because most states measure the combined reading of film plus glass, adding film over privacy glass drops the number further than the film label suggests. See how film and glass add up in our VLT guide.

Windshield tint in California

The rule for the windshield is: Non-red/amber, non-glare strip above 29-inch line (AS-1 area). The AS-1 line is a small mark etched near the top of the glass; our guide shows how to find the AS-1 line on your car.

Choosing film that passes in California

Reflectivity is regulated too: no numeric limit. Windshield film may not reflect sunlight or headlight glare into other drivers' eyes any more than the untinted glass would.. Metallic films are the type most likely to run into reflectivity limits, while carbon and ceramic films are non-reflective. Compare them in types of window tint film.

With front windows this strict, the usual approach is a light ceramic film on the fronts. It keeps the cabin noticeably cooler and blocks UV without dropping below the legal reading, and you can still go darker behind the driver where the law allows.

If you get a tint ticket

Usually a correctable fix-it ticket: show proof of correction and pay a small fee (commonly about $25). If not corrected, or charged as a standard infraction, the total with penalty assessments is typically about $197 or more. No DMV points.

No sticker, but clear film on the front side windows requires a certificate in the vehicle, signed by the installer (full name and street address) or, for self-installs, by the film manufacturer. To see how California stacks up, read window tint penalties by state. If you need darker film for a medical reason, the medical exemption guide covers what most states ask for.

Reflectivity and other rules

Reflectivity: No numeric limit. Windshield film may not reflect sunlight or headlight glare into other drivers' eyes any more than the untinted glass would.

  • Aftermarket film on the front side windows must be clear, colorless and UV-A blocking, with at least 88% VLT, and the glass plus film must still meet 70% (FMVSS 205)
  • The windshield strip may not be red or amber or carry opaque lettering, and its bottom edge must be at least 29 inches above the driver's seat
  • Tinting the rear window requires outside mirrors on both sides that show at least 200 feet behind
  • Torn, bubbled or worn film that impairs vision must be removed or replaced
  • Factory-tinted safety glass is allowed where federal glazing standards permit it

Stickers and certification

No sticker, but clear film on the front side windows requires a certificate in the vehicle, signed by the installer (full name and street address) or, for self-installs, by the film manufacturer.

Penalties

Usually a correctable fix-it ticket: show proof of correction and pay a small fee (commonly about $25). If not corrected, or charged as a standard infraction, the total with penalty assessments is typically about $197 or more. No DMV points.

California medical exemption

With a letter from a licensed physician or optometrist, the driver or front passenger may use removable sun-screening devices on the front side windows, but not in darkness (Veh. Code § 26708.2). Separately, a licensed dermatologist's certificate stating the person must avoid UV exposure allows clear UV-blocking film (88%+ VLT) on any window; keep the certificate in the vehicle. California does not issue a state permit for darker front tint.

California tint law questions

What is the darkest legal tint in California?

Back side and rear windows may be any darkness on all vehicles, as long as the car has dual side mirrors when the rear window is tinted. Front side windows may only have clear film of at least 88% VLT, and the glass plus film must still let in 70% of light.

Can I get a medical exemption for tint in California?

Yes, but limited. A licensed physician's or optometrist's letter lets you use removable sun-screening devices on the front side windows during daylight only. A licensed dermatologist's certificate allows clear UV-blocking film on any window. Neither allows dark film on the front side windows, and California issues no state permit.

Is 20% tint legal in California?

Only on the back side and rear windows, with dual side mirrors when the rear window is tinted. It is illegal on the front side windows and the windshield.

How much is a tint ticket in California?

Most tint citations are correctable fix-it tickets: remove the illegal film, get the correction signed off, and pay a fee of about $25. If you don't correct it, or it is charged as a regular infraction, the total with assessments typically runs about $197 or more. No points are added.

What happens if I drive through California with dark tint?

California's tint rules apply to every vehicle on its roads, so officers can cite out-of-state cars with dark front side windows, usually as a correctable fix-it ticket.
