California has some of the strictest window tinting regulations in the country, and most drivers who get ticketed never saw it coming. Whether you are cruising through Rocklin, CA, or commuting across the Sacramento area, understanding California window tint laws in 2026 is not optional. It is how you avoid a fine, a fix-it ticket, and a trip back to the shop. The governing statute is California Vehicle Code 26708, and this guide breaks down exactly what it means for your vehicle, window by window.
What Is California Vehicle Code 26708?
California Vehicle Code 26708, or CVC 26708, is the state law that controls what you can and cannot put on your vehicle windows. It covers all passenger vehicles sedans, SUVs, trucks, and vans and applies to both the original factory glass and any aftermarket window film added later. In plain terms: it sets the rules for how dark, how reflective, and what color your tint can be. Breaking any part of it is grounds for a citation.
California Window Tint Percentage Rules by Window Position

Not all windows are treated equally under California law. Here is what the rules say for each position on your vehicle.
Front Windshield
California only allows a non-reflective tint strip on the top 4 inches of the windshield, above the AS-1 line, the manufacturer’s mark near the edge of the glass. No full windshield tinting is permitted for standard passenger vehicles.
The exception most drivers miss: a clear ceramic film maintaining 70% visible light transmission or higher can be applied across the full windshield legally. It blocks infrared heat and UV rays without visible darkening and without violating the law.
Front Side Windows (Driver and Passenger)
This is the section that trips up the most drivers. California tint percentage front windows law requires a minimum of 70% visible light transmission on the driver and passenger side windows.
Here is where it gets technical: California measures the VLT percentage as the combined reading of the factory glass plus the aftermarket film together. Since most modern factory glass already sits at 74% to 85% VLT, any film added on top reduces that number. To keep the combined reading above 70%, the aftermarket window film itself must have a VLT of 88% or higher.
This is the number one reason Rocklin drivers get ticketed. The tint looks light, but the combined VLT drops below the legal threshold without proper measurement.
Rear Side Windows
Good news here. California places no VLT restriction on rear side windows. How dark can you tint windows in California on the rear sides? As dark as you want, including limo tint at 5% VLT, which blocks 95% of visible light.
The darkest legal tint in California for rear side windows is effectively unlimited. Most drivers settle on 20% to 35% VLT for a combination of privacy, heat rejection, and comfortable nighttime visibility.
Rear Windshield
The darkest legal tint in California applies here too; any darkness is permitted on the rear windshield. The one condition: if the rear window is tinted, the vehicle must have dual side mirrors. This applies to all vehicle types, including SUVs and trucks.
Quick Reference: California Legal Tint by Window
| Window | Legal Tint (VLT) | Notes |
|---|---|---|
| Front Windshield | Top 4 inches only | Non-reflective, above AS-1 line |
| Front Side Windows | 70% minimum | Film must be 88%+ VLT |
| Rear Side Windows | Any darkness | No restriction |
| Rear Windshield | Any darkness | Dual mirrors required |
What Tint Colors Are Illegal in California?
What colors of tint are illegal in California? Under CVC 26708, red, amber, and blue tint films are banned on all windows. These colors are reserved for emergency vehicles and traffic control signals. Any aftermarket film in these shades will result in a citation regardless of how light the VLT is.
Stick to neutral gray, charcoal, or clear films. LLumar films, the brand Sterling Window Tinting installs exclusively, are available in fully compliant, non-reflective shades that meet California standards across all window positions.
California Window Tint Penalties and Fines
Can you get pulled over for window tint in California? Yes, and it does not require another reason. Illegal window tint is a primary offense in California, meaning California Highway Patrol officers can initiate a stop based on suspected illegal tint alone.
A first offense results in a fix-it ticket for window tint under CVC 26708. The base fine is $25, but court fees and assessments bring the real total to around $197. The driver has 30 days to remove or replace the illegal film and have the correctable violation signed off by a law enforcement officer.
Repeat offenses carry higher fines and may no longer qualify as correctable violations. A second window tint ticket in California within 12 months can result in fines exceeding $200 and potential impacts on your driving record.
Does Factory Tint Count Toward VLT in California?
Does factory tint count toward VLT in California? Yes, and this surprises a lot of drivers. California law measures the combined VLT percentage of the factory glass and the aftermarket window film together, not the film alone.
Most modern vehicle glass sits at 74% to 85% VLT straight from the factory. Add an aftermarket film rated at 90% VLT, and the combined reading could still drop below 70%, depending on the base glass. A professional installer should always measure the existing glass before applying anything to front-side windows; this is non-negotiable in California.
California Window Tint Medical Exemption
California offers a window tint medical exemption that California drivers can apply for under Assembly Bill 1303. A licensed physician or optometrist must provide a signed certificate identifying the qualifying medical condition.
Qualifying conditions include lupus, melanoma, photosensitivity disorders, and similar light-sensitive diagnoses. The exemption allows front side windows down to 35% VLT. The certificate must be kept in the vehicle at all times and presented if stopped.
Note: The medical exemption does not apply to the windshield. The ” Can I tint my windshield in California question is governed separately. Only the top 4-inch strip or a clear ceramic film at 70%+ VLT is permitted regardless of medical status.
