Oregon has both a film requirement and a finished-window requirement. For ordinary side and rear tint, the film must transmit at least 50%, and the installed glass-and-film combination must transmit at least 35%.
Read the official sources ↓Rules by window
| Window | Requirement |
|---|---|
| Windshield | Tint may be applied only to the top 6 inches. That band has an exception from the ordinary transmission minimums. |
| Front side | Film at least 50% transmission and finished window at least 35%, unless a documented medical exception permits lower transmission. Film reflectance must remain no more than 13%. |
| Rear side | Ordinary 50% film/35% combined requirements; qualifying multipurpose-passenger vehicles may use darker rear glass with both outside mirrors and the specified AS-3 compliance. |
| Rear window | Ordinary 50% film/35% combined requirements, with the qualifying multipurpose-vehicle and AS-3 provisions. |
Qualifying vehicles and appearance
The multipurpose-passenger definition requires no more than 10 persons and a truck chassis or special features for occasional off-road operation. Mirror-finish products; red, gold, yellow, amber, or black material; and brushed- or sprayed-on liquid tint are prohibited. Do not decide the vehicle class from an SUV badge alone.
Keep the certificate
The installer must provide a certificate with its name and address, film transmission and reflectance, and the required installed-window statement. Keep it in the vehicle and show it when police ask about tint.
Medical documentation
Darker side and rear tint may qualify when the vehicle is registered to the person or legal guardian and a licensed physician or optometrist documents a qualifying physical condition of the person or household member. The statute accepts an affidavit, prescription, or practitioner-letterhead letter. Keep it in the vehicle; this provision does not authorize full-windshield tint.
Before you rely on this guide
This is general information, not legal advice, a vehicle inspection, or permission to install a particular film. Exceptions and enforcement procedures can depend on your circumstances.
- ORS 815.221(9)(d) requires the installer certificate to state at least 35% total transmission through each tinted window, while separate provisions allow qualifying darker tint. The reviewed sources do not resolve the certificate wording for those exceptions; confirm the documentation before relying on one.
