In Oregon, legal tint is measured by VLT — the percentage of light the filmed glass lets through. The numbers below are the darkest tint the law allows at each window position, labeled VLT MAX: install film darker than the listed VLT and the vehicle is out of compliance. Figures are compiled from official Oregon state sources; laws change, so confirm the current statute before you tint.
| Window | Darkest Legal (VLT MAX) | Reflectivity |
|---|---|---|
| Windshield | No full-windshield figure — tinting material darker than the subsection (2) standards may be applied only to the top six inches of the windshield; tinting material may not be applied to any other portion of the windshield — § 815.221(3) | |
| Front side windows | 35% total — the tinting material must itself have a light transmittance of 50% or more, a light reflectance of 13% or less, and the total light transmittance through the window with the material applied must be 35% or more — § 815.221(2)(a)–(c) | |
| Rear side windows | 35% total — the same dual standard as the front side windows: material transmittance 50% or more, reflectance 13% or less, total transmittance 35% or more — § 815.221(2)(a)–(c). Darker exception for multipurpose passenger vehicles behind the driver — see riders | |
| Rear window | 35% total — the same dual standard: material transmittance 50% or more, reflectance 13% or less, total transmittance 35% or more — § 815.221(2)(a)–(c). Darker exception for multipurpose passenger vehicles behind the driver — see riders |
How to Read These Numbers
- Windshield: The windshield rule controls the strip at the top of the glass and how far film or a visor band may extend down. Most states allow a non-reflective strip above the manufacturer's AS-1 line.
- Front side windows: Front side windows — driver and front passenger — are the most tightly regulated and the ones checked first at a traffic stop or inspection.
- Rear side windows: Rear side windows are usually allowed darker than the fronts, and on SUVs, trucks and vans they are sometimes exempt from the passenger-car limit.
- Rear window: The rear window rule often interacts with side mirrors: darker rear glass typically requires dual outside mirrors.

Oregon Tint Law Questions
What is the darkest legal tint in Oregon?
For front side windows, Oregon allows tint down to 35% total — the tinting material must itself have a light transmittance of 50% or more, a light reflectance of 13% or less, and the total light transmittance through the window with the material applied must be 35% or more — § 815.221(2)(a)–(c) — the VLT MAX. Rear windows may allow darker film; check the table above for each position.
What happens if my tint is darker than Oregon allows?
Over-dark tint can draw a citation and, in many states, a fix-it order requiring the film to be removed and the vehicle re-inspected. Laws also change — verify the current statute before tinting.
