The Complete Legal Guide to San Diego Window Tint Laws (CVC §26708 Decoded)
Key Takeaway
California Vehicle Code §26708 governs window tint for all vehicles registered in California, including San Diego. Front side windows must allow 70% or more visible light transmittance. The top 4 inches of the windshield may have non-reflective tint. Rear side and back windows have no darkness limit. CHP, San Diego Police, and the San Diego Sheriff enforce the statute, primarily during traffic stops, with handheld VLT meters. First-offense violations are typically fix-it tickets under §26708.5.
California Vehicle Code §26708 is the single statute that controls every legal question about window tint in San Diego. This guide decodes it, line by line, and points you straight at the primary government sources so you can verify everything yourself.

The VLT Rules (What §26708 Actually Says)
- Windshield: Top 4 inches only, non-reflective film.
- Front side windows: Must allow 70%+ visible light transmittance.
- Rear side windows + back glass: Any darkness allowed.
- Reflective / mirrored film: Prohibited at any VLT.
Industry installer standards published by the International Window Film Association require a manufacturer label on each tinted window per §26708.5.
Fix-It Tickets and the Court Process
A first-offense citation in San Diego is almost always issued as a "correctable violation" under §26708.5. The court process is documented on courts.ca.gov — you remove the illegal film, get sign-off from a court-approved inspector, and pay a $25 dismissal fee.
Medical Exemption (CVC §26708(d)(2))
Drivers with qualifying medical conditions can legally install darker front-side tint. Read our full California medical exemption guide or visit our medical exemption page.
