Legal tint limits at a glance
VLT is the share of light the window must let through — a lower number is darker film, and the reading includes the factory glass.
| Window | Sedans | SUVs, vans & trucks |
|---|---|---|
| Windshield | Non-reflective tint permitted only on the top 6 inches of the windshield; the rest of the windshield may not be treated | Same top-6-inch rule as sedan |
| Front side | 35% VLT or lighter | 35% VLT or lighter |
| Back side | 35% VLT or lighter | No limit stated |
| Rear | 35% VLT or lighter | No limit stated |
Dual side mirrors required if the rear is tinted? Yes — this state requires dual outside mirrors when the rear window is tinted.
Is my tint legal here?
Film darkness and glass darkness multiply. Enter the film you are considering and the VLT of the bare glass to get the number a meter would read.
70 for tinted OEM glass, 80 for clear
Net VLT 14% 20% film × 70% glass
Pass/fail compares net VLT against the limits on this page only. Some states apply a measurement tolerance — see Measurement tolerance below — and none of this replaces a meter reading on your own glass.
The rest of the rule
Reflectivity
Light reflectance must be ≤13% on treated windows
Colors
Mirror-finish products; red, gold, yellow, amber, or black material; liquid tint applied by brushing or spraying is also prohibited
Medical exemption
ORS 815.221 references documentation from a physician/optometrist that must be carried in the vehicle; third-party sources (not independently verified on a primary Oregon DMV/ODOT page) describe a DMV Form 735-6513 process allowing tint down to 20% VLT — flagged as unconfirmed on a primary source
Stickers & certification
Installer must provide a certificate stating installer name/address, light transmittance, light reflectance, and confirmation that total window transmittance is ≥35%; certificate must be kept in the vehicle
Measurement tolerance
This state does not state a measurement tolerance in the sources we checked.
Penalties
Class B traffic violation under ORS 815.222; courts may dismiss a citation if the tint is corrected or valid medical documentation is provided
Notes
For ordinary passenger cars, front side/back side/rear all need ≥35% TOTAL transmittance through glass+film combined (film alone must transmit ≥50%). For multipurpose vehicles (vans/SUVs), windows behind the driver may be any darkness if the vehicle has dual outside mirrors meeting the AS-3 glazing standard — front side windows remain capped at 35% for MPVs too.
Oregon tint questions
What is the darkest legal tint in Oregon?
For a sedan in Oregon, front side windows must let at least 35% of light through, back side windows at least 35%, and the rear window at least 35%. Lower VLT means darker glass, so those percentages are floors, not targets, and the meter reads the film and the factory glass together. SUVs, vans and trucks are listed separately: front side 35%, back side no stated number, rear no stated number.
Is 20% tint legal in Oregon?
No, not on the front side windows. Oregon requires at least 35% VLT there and 20% is darker than that, before you even account for the factory glass, which makes the reading darker still. The back side windows have a 35% floor, so 20% is too dark there too.
Can I tint the windshield in Oregon?
Oregon's rule for the windshield: Non-reflective tint permitted only on the top 6 inches of the windshield; the rest of the windshield may not be treated
Does Oregon allow a medical exemption for darker tint?

Do I need a tint sticker or certificate in Oregon?
