What is the darkest legal tint in California?

California's window tinting law specifies standards for each window of a vehicle to maintain optimal visibility when tinted:

• The front windshield may only have a non-reflective tint strip along the top edge (not red or amber), ending at least 29 inches above the driver’s seat, which in most cars means the top few inches. Clear, colorless UV film (88%+ VLT) on the rest of the windshield is allowed only with a certificate from a licensed dermatologist.
• Side windows on the front doors may only have clear, colorless, UV-blocking film with at least 88% VLT, and the glass with film must still let through at least 70% of light. Tinted film, including 30% or 35% shades, is not legal on the front side windows.
• Rear side windows can be tinted to any darkness. The rear window can also be tinted to any darkness, as long as the vehicle has outside mirrors on both sides.

Service providers applying window tint typically inform customers about these regulations. However, it's crucial to clarify any concerns about compliance before tinting to avoid potential issues later.

Police officers may stop vehicles with apparent excessive tint and use a tint meter to measure light transmission. A tint violation is usually written as a correctable “fix-it” ticket: you remove the illegal film and submit proof of correction, and the court charges a $25 transaction fee. Officers can also issue a regular citation, and total costs vary by county.

Ensuring compliance with California's tinting laws is essential to avoid legal consequences.

Now you know the rules: clear film on the front side windows, and any darkness on the rear side windows and rear window. But not all tints are created equal.

FAQs

Q: Is 35% Window Tint Legal?

A: Not on the front side windows. In California, 35% tint is legal only on the rear side windows and the rear window (the rear window requires outside mirrors on both sides). The front side windows may only have clear, colorless film with at least 88% VLT. Failure to comply can result in a ticket and the need to remove the film.

Q: What Is the Darkest Tint You Can Have on Your Vehicle Windows?

A: On the rear side windows and the rear window (with outside mirrors on both sides), there is no darkness limit, so even 5% is legal. The front side windows may only have clear, colorless film with at least 88% VLT, and the windshield may only have a non-reflective strip along the top edge.

Q: How Much Is a Tint Ticket?

A: A tint violation is usually a correctable “fix-it” ticket: you remove the illegal film, submit proof of correction, and pay a $25 court transaction fee. Officers can also issue a regular citation, and total costs vary by county. Prompt correction helps avoid harsher penalties.

Q: Can Window Tint Cause an Accident?
