The short answer: In Oregon, drivers may tint windows so that at least 70 percent of light passes through the front side windows, while the rear side and back windows can be tinted down to 35 percent VLT (visible light transmission). These limits will remain in effect throughout 2026, and any tint darker than the allowed percentages can trigger a traffic stop, a citation, and a requirement to remove the illegal film.
Oregon’s Tint Limits for 2026
Oregon follows the “70‑35 rule.” Front side windows (including the driver’s side) must permit a minimum of 70 percent of visible light, measured with a calibrated tint meter. The rear side windows and the rear windshield may be darker, but must still allow at least 35 percent of light. The front windshield is exempt from tint, except for a thin non‑reflective strip at the top for glare reduction.
How Tint Is Measured
Tint depth is expressed as a VLT percentage. A 70 percent rating means that 70 percent of external light reaches the interior, while 30 percent is blocked. Law‑enforcement officers use handheld photometers to verify compliance. If a vehicle’s reported VLT does not match the meter reading, the officer can issue a citation on the spot.
Penalties for Non‑Compliant Tint
A first‑offense citation typically carries a fine of $150‑$250, plus a requirement to strip the illegal film within a designated period. Repeat offenses may lead to higher fines and the vehicle being deemed non‑roadworthy until the tint is removed or corrected. Courts may also assess court costs and a driver‑license point, depending on the jurisdiction.
Frequently Asked Questions
What happens if I have factory‑installed tint that exceeds Oregon’s limits?
Factory tint is treated the same as aftermarket film. If the VLT is lower than the legal threshold, the vehicle must be re‑tinted or the film removed to avoid citation.
Can I apply a privacy tint on the rear windows of a commercial vehicle?
Yes, commercial vehicles may use the 35 percent rear‑window limit, but the front side windows must still meet the 70 percent requirement. Some local jurisdictions impose stricter rules for fleet vehicles, so check with the local motor vehicle department.
Are there exemptions for medical conditions?
Oregon allows a medical exemption for drivers who require additional UV protection or glare reduction. The driver must submit a physician’s statement and obtain a special permit, which permits darker tint on the front side windows consistent with the medical need.
Does the law affect aftermarket window stickers or decals?
Stickers, decals, or any material that reduces light transmission are counted toward the VLT limit. Even clear stickers that cover a significant portion of the glass can render the window non‑compliant if they drop the overall light level below the legal threshold.
How often do Oregon’s tint regulations change?
Oregon’s tint standards have remained unchanged since the early 2000s, and there are no pending legislative proposals to alter the 70‑35 rule for 2026. Drivers can rely on the current limits unless a future ballot measure or legislative amendment is enacted.
