Oregon Window Tint Laws (2026): Legal VLT Limits
Oregon Window Tint Laws (2026): Legal VLT Limits
Oregon requires window tint film on front side windows to allow at least 50% VLT on its own, and the combined film-plus-glass must allow at least 35% VLT. Passenger car back side and rear windows follow the same standard, while multipurpose vehicles (SUVs, vans, and trucks) may run any darkness behind the driver if they have dual outside mirrors.
What is the legal tint limit in Oregon?
Oregon's tint law works in two layers, which makes it somewhat unique. The film itself must allow at least 50% Visible Light Transmission (VLT). But beyond that, the combined transmittance of the film and the factory glass together must be at least 35% VLT. A higher VLT% means lighter tint; a lower VLT% means darker tint. Most factory glass already absorbs some light, so a 50% film applied to glass that passes 80% of light would yield a combined VLT of about 40%, which is above the 35% threshold. If your factory glass is already dark, you have less room to add tint.
For passenger cars (sedans), the dual standard applies to all side windows, including the windows behind the driver. For multipurpose vehicles (SUVs, vans, and trucks), the same rules apply to the front side windows, but the windows behind the driver and the rear window have no VLT restriction, as long as the vehicle has dual outside mirrors providing an adequate rear view.
| Window Position | Passenger Car | Multipurpose Vehicle |
|---|---|---|
| Front side windows | Film 50% min; combined 35% min | Film 50% min; combined 35% min |
| Back side windows | Film 50% min; combined 35% min | Any darkness (dual mirrors required) |
| Rear window | Film 50% min; combined 35% min | Any darkness (dual mirrors required) |
| Windshield | Top 6 inches only, non-reflective | Top 6 inches only, non-reflective |
Oregon's 13% reflectivity cap is stricter than many states. That means highly reflective or mirrored films are off the table regardless of how much light they transmit.
Windshield tint rules in Oregon
Oregon allows tint film on the windshield only within the top 6 inches. Below that line, the windshield must be free of any added film. The permitted strip must be non-reflective. Spray-on tint is expressly prohibited on any window, not just the windshield.
Several colors are banned across all windows. Red, gold, yellow, amber, and black tint films are not lawful in Oregon. Mirror-finish films are also prohibited statewide. These bans apply to every window on the vehicle, not just the windshield strip. When shopping for film, confirm that the product does not carry any of these color designations and that it is not marketed as a mirror or reflective finish.
The 13% reflectivity limit is relatively strict. Many states allow 20 to 35% reflectance. Oregon's lower ceiling means even lightly metallic gray films may push past the legal line. Ask your installer to measure reflectance before installation if the film you want has any metallic content.
Medical exemptions
Oregon allows a medical exemption for window tint that exceeds the standard VLT limits. To qualify, you need written certification from a physician or optometrist documenting a medical condition that requires reduced light exposure. Common qualifying conditions include photosensitivity disorders, certain autoimmune diseases, and post-surgical eye conditions.
You do not file the documentation with a state agency. Instead, you keep the written certification in the vehicle at all times and present it to law enforcement if the vehicle is stopped. Without the documentation in the car, the exemption provides no protection during a traffic stop. If you change vehicles or renew the certification, make sure the updated paperwork travels with the car. Oregon's exemption rules are set under ORS 815.221 and associated administrative guidance, so consult the Oregon DMV or your physician for current details.
How tint is measured and certified
Tint is measured with a VLT meter, a device that shines a light through the glass and measures how much passes through. Oregon's dual-standard rule means a meter reading the combined film-plus-glass must show at least 35%, while a separate reading of only the film must show at least 50%. In practice, most officers and inspectors measure the combined reading at the window itself. If you are concerned about a specific film, ask your installer to take both readings before the installation is complete.
Oregon does not require a compliance sticker on the vehicle. However, the installer is required to provide a certificate of transmittance and reflectance to the vehicle owner. This document shows the measured VLT and reflectance values for the film installed. Keep this certificate in the glove box alongside any medical documentation. It will not prevent a stop, but it can help demonstrate compliance if you are cited and contest the ticket.
No specific measurement tolerance is listed in ORS 815.221, so any reading that measures below the threshold may result in a citation. If you are close to the limit, erring on the lighter side of the range is the safer choice.
Penalties for illegal tint in Oregon
Driving with non-compliant window tint in Oregon is a Class B traffic violation under ORS 815.222. The fine is approximately $360. A Class B violation does not carry the risk of jail time, but the fine is considerably higher than in states that treat tint as a minor correctable infraction.
Oregon does not have a statutory fix-it-ticket mechanism for tint violations in the same way some other states do, though a court may consider remediation. If you receive a citation, you can contest it by presenting measurement evidence showing your tint is within the legal limits. Removing or replacing non-compliant film before your court date may be taken into account, but it does not automatically dismiss the citation.
Installers who knowingly put on illegal tint may also face liability under Oregon law. When selecting an installer, confirm in writing that the film they plan to use meets Oregon's dual VLT standard and the 13% reflectivity cap.
If you want to tint your windows in Oregon
Start by selecting a film that is rated at 50% or higher VLT on its own. Do not assume a 50%-rated film will automatically produce a compliant combined reading with your specific factory glass. Ask the installer to measure the combined transmittance through your vehicle's glass before cutting the film, and confirm the reflectance does not exceed 13%.
Avoid any film sold as red, gold, yellow, amber, or black in color, and avoid mirror-finish or spray-on products. These are banned regardless of how much light they transmit. Stick with neutral tones (gray, charcoal, ceramic, or smoke finishes) that carry no color designation.
After installation, get the transmittance and reflectance certificate from the installer and keep it in the vehicle. If you have a medical exemption, keep that documentation in the car as well. If you drive an SUV, van, or truck, remember that your front side windows must still meet the full dual standard even though your rear side windows and rear window are unrestricted.
If you are buying a used vehicle in Oregon, inspect any existing tint carefully. The prior owner's compliance is not guaranteed, and you will be responsible for the tint on the vehicle you drive.
