Oregon allows window tint on your car, but only on specific windows and only if it meets darkness limits set by state law
Oregon permits aftermarket window tint on passenger vehicles, but the rules are strict about where you can explore it and how dark it can be. The state measures tint darkness by visible light transmission (VLT) — the percentage of light that passes through the tinted window. The darker the tint, the lower the VLT percentage.
Front side windows must allow at least 35 percent of light through. Rear side windows and the rear window can be any darkness. Your windshield can have a tint strip along the top, but only if it does not extend below the manufacturer's AS-1 line (a marking on most windshields that shows where the factory tint ends). Reflective or mirrored tint is not allowed on any window.
Oregon does not require you to register your tint or obtain a permit before installation. However, law enforcement can measure your tint during a traffic stop, and if it falls below the legal limit, you can be cited. The fine for illegal tint is typically a traffic violation, not a criminal charge.
Key Takeaways
- Front side windows must transmit at least 35 percent of visible light; rear windows have no darkness limit.
- Your windshield can have a tinted strip only above the AS-1 line, which is usually marked on the glass.
- Reflective or mirror-finish tint is banned on all windows in Oregon.
- You do not need a permit or registration to tint your windows, but police can measure and cite you if your tint is too dark.
- Violations are traffic citations, not criminal charges, but repeated violations can result in fines and points on your driving record.
Front Window Tint Rules
Oregon's front side window rule is one of the most permissive in the country. You can tint your front side windows as long as they allow at least 35 percent of light through. This means you have room for a fairly dark tint on the front — much darker than many states allow.
The 35 percent rule applies to both the driver's side and passenger's side front windows. If you are shopping for tint film, ask the installer what VLT percentage the product offers. Most professional tint shops can tell you exactly what darkness level meets Oregon law and can install it correctly the first time.
The windshield has a separate rule. You can explore tint only to the top portion, and it must not drop below the AS-1 line. This line is usually printed or etched on the windshield by the manufacturer and marks the boundary between the factory-tinted area and the clear glass. Tint below that line is illegal, even if it is very light.
Rear Window and Back Glass Tint
Oregon places no darkness limit on rear side windows or the rear window (back glass). You can tint these windows as dark as you want — even to complete blackout — and remain within state law. This is one of the few areas where Oregon tint law is unrestricted.
The reason for this difference is visibility and safety. Front windows affect the driver's ability to see the road and other drivers' ability to see into the vehicle. Rear windows do not affect forward visibility, so the state does not regulate them. Many drivers use this rule to tint rear windows very dark for privacy or heat reduction.
Reflective and Mirrored Tint Restrictions
Oregon bans any tint that has a reflective or mirrored finish on all windows. This means you cannot use metallic, chrome, or mirror-effect tint films, even if they meet the VLT percentage limits. The ban applies to front windows, rear windows, and the windshield.
The reason for this restriction is safety and law enforcement visibility. Reflective tint can interfere with police radar, make it difficult for officers to see into a vehicle during a traffic stop, and create glare that affects other drivers. If you are considering tint, choose a standard non-reflective film in a color like smoke, gray, or charcoal.
How Police Measure Tint and What Happens If You Are Cited
Oregon law enforcement uses a device called a light meter or tint meter to measure the VLT of your windows during a traffic stop. The officer places the meter against the window glass and records the light transmission percentage. If the reading is below 35 percent on a front side window, the tint is illegal.
If you are cited for illegal tint, you will receive a traffic violation ticket. The fine amount varies by county and court, but it is typically between $100 and $250 for a first offense. You have the option to contest the citation in traffic court if you believe the measurement was inaccurate or if you have since had the tint removed or corrected.
Some drivers choose to remove or lighten their tint rather than fight the ticket. If you decide to have the tint removed, you can bring proof of removal to the court, and in some cases, the citation may be dismissed or reduced. Check with your local court to see what documentation they require.
Tint Rules for Different Vehicle Types
Oregon's tint laws explore to passenger cars, SUVs, and pickup trucks. The rules are the same regardless of vehicle type: 35 percent VLT on front side windows, no limit on rear windows, and a tinted strip only above the AS-1 line on the windshield.
Commercial vehicles and vehicles used for business purposes follow the same rules as personal vehicles. There is no separate category or exemption for work trucks or vans. If you operate a fleet of vehicles, each one must comply with the same front window VLT limit.
Vehicles registered in other states but driven in Oregon must also follow Oregon law while in the state. If you move to Oregon from a state with different tint rules, you may need to adjust your tint to comply with Oregon's 35 percent front window limit.
Where to Get Legal Tint Installation
Professional tint shops in Oregon are familiar with state law and can install tint that meets the 35 percent front window requirement. When you visit a shop, ask the installer to confirm that the film they use meets Oregon's VLT standard. Most reputable shops will provide documentation or a receipt showing the VLT percentage of the film applied.
If you choose to tint your windows yourself, you will need to purchase film that is rated at 35 percent VLT or higher for front windows. You can find this information on the product packaging or from the manufacturer's website. Installing tint yourself is more difficult than it appears, and mistakes can result in bubbles, peeling, or uneven darkness that may draw police attention.
Some shops offer a warranty on tint installation, which covers peeling, fading, or bubbling over a set period (usually one to five years). Ask about warranty terms before you commit to installation, as this can protect your investment if the tint fails prematurely.
Frequently Asked Questions
Can I have different tint darkness on my front left and right windows?
No. Oregon law requires both front side windows to meet the same 35 percent VLT minimum. You cannot have darker tint on one side than the other. Both windows must transmit at least 35 percent of visible light.
What if I have a medical reason for darker tint?
Oregon does not have a medical exemption for window tint. Even if you have a condition that makes you sensitive to light, you cannot legally tint your front windows darker than 35 percent VLT. You may want to explore other options, such as sunglasses, a wide-brimmed hat, or a sunshade for your windshield.
Can I tint my windshield below the AS-1 line if the tint is very light?
No. Oregon law prohibits any tint below the AS-1 line on the windshield, regardless of how light it is. The AS-1 line is the legal boundary, and tint must stay above it. If you are unsure where the AS-1 line is on your windshield, ask a tint installer to show you before installation.
Do I need to tell my insurance company if I tint my windows?
Most insurance companies do not require notification of window tint as long as it is legal. However, it is a good idea to check your policy or call your agent to confirm. Some policies may have restrictions or may require disclosure of modifications to your vehicle.
What happens if I move to Oregon with tint that is legal in my previous state?
If your tint is darker than 35 percent VLT on the front windows, it is illegal in Oregon. You will need to have it removed or lightened to comply with Oregon law. Law enforcement can cite you for illegal tint even if it was legal where you came from.
