Washington State Window Tint Laws 2026: The Complete Legal VLT Percentage Guide for Los Angeles Drivers, Seattle Commuters and Bi-Coast Owners

The short answer for LA drivers heading to Washington in 2026

If you live in Los Angeles and you're either moving to Seattle, splitting time between a place in Silver Lake and a condo in Bellevue, or sending a kid to school in Spokane with the family car, here's the line you need to remember. Washington state requires 24% VLT or lighter on every window of a passenger car except the windshield. That's it. No 20%, no 15%, no limo black on the back glass of a sedan. Twenty-four percent is the floor, and there is no five-percent tolerance the way some states quietly allow. I've been tinting cars on Sunset Blvd for three decades and I can tell you the number-one reason an LA client gets a ticket up north is they assume Washington works like California or Nevada. It does not.

The other quick truth. If your vehicle is classified as an SUV, truck, van, or multi-purpose vehicle by the manufacturer (think Tahoe, Tacoma, 4Runner, Sprinter, most three-row crossovers), Washington lets you go any darkness you want on the rear side windows and back glass, but the front two side windows still have to hit that 24% mark. We do this combo all the time at our shop on Sunset between Hollywood and Los Feliz for clients who keep one car in Los Angeles and one at a place in Kirkland or Redmond. A 24% front, dark rear setup is honestly the cleanest dual-state legal build you can put on a truck in 2026.

Why this matters if you cross the border

I've watched the tech migration north for ten years now. We tint cars in Hancock Park and Beverly Hills on Monday and the same customer is driving an Audi Q5 up the I-5 corridor by Friday because they took a remote-hybrid role at one of the big Bellevue or Redmond campuses. The Pacific Northwest does not have the same sun problem we deal with in Mid-City or Koreatown, where a south-facing parked car will hit 140 degrees on the dash in August. But the rain, the low gray winter light, and the long commute on I-5 through Tacoma into Seattle create a totally different set of visibility issues. Tint that works perfectly for a Tesla in DTLA at noon can be genuinely unsafe at 6 a.m. on the Mercer Island bridge in February.

It also matters because Washington State Patrol enforces tint. They actually pull people over for it. I'm not exaggerating. Trooper-issued tickets in King and Pierce counties for illegal tint are common enough that we've had clients drive back down to our shop on Sunset Blvd specifically to get film stripped and replaced before going back. If you do business in both states, if you've got a primary residence in Echo Park and a vacation house in Bellingham, if you're a film industry crew member who travels constantly between LA shoots and Seattle commercial work, you need a film spec that doesn't get you stopped in either jurisdiction. That's what this whole guide is going to lay out for you.

Quick credibility note before we go further. We are an XPEL-authorized dealer at 5300 Sunset Blvd in Los Angeles, and we install the full XPEL film lineup on everything from daily-driver Civics in Highland Park to seven-figure McLarens in Beverly Hills. We're not film-agnostic and I'm not going to pretend we are. But the law information here is straight from the Revised Code of Washington and Washington State Patrol bulletins, and it applies to any film you put on the glass, ours or someone else's. If you want to see what we install, our XPEL window tinting services page covers the full lineup.

Section 1: Washington's VLT rules, plain English

VLT stands for Visible Light Transmission. It's a percentage. The higher the number, the more light the window lets through. A factory window with no tint at all is somewhere around 70 to 80 percent VLT depending on the manufacturer. A piece of limo film is around 5 percent. When Washington says you need 24% VLT minimum, they're talking about the combined glass plus film reading after install. Not the film alone. That's a critical distinction and it's where most DIY jobs get people in trouble. If you put 35% film on a factory window that's already lightly tinted from the glass plant at 70%, your combined reading is going to come out somewhere around 24 or 25 percent. Cutting it close. We measure every install with a calibrated meter for exactly this reason.

Here are the actual numbers as written into the Revised Code of Washington under RCW 46.37.430. Passenger cars (sedans, coupes, two-door cars, basically anything not classified as an MPV) need 24% VLT or more on the driver and front passenger windows, on the rear side windows, and on the rear window. The only window exempt from the 24% floor is the windshield, and the windshield has its own rule we'll cover in section four. There is no exception for a darker rear window on a sedan in Washington. I want to repeat that because LA clients get this wrong almost every visit. A sedan in Washington cannot have darker tint on the back than the front. Same number across the board.

For SUVs, pickup trucks, vans, and what the state calls multi-purpose vehicles, the front two windows still need 24% or more, but you can run any darkness you want on the rear side windows and the back glass. So a Bronco, a Wrangler four-door, a Sequoia, an Escalade, all of those can run a 24% front and a 5% rear if that's what you want, and it is fully legal under Washington law as long as the front two are properly measured at 24 or above. We do a lot of these builds. They're popular with our Pasadena and Glendale clients who like a stealthy look on the back without giving up legality.

One more piece. Washington does require dual outside mirrors if the rear window has any aftermarket tint on it. Every modern vehicle made in the last 25 years comes with dual side mirrors from the factory, so this is rarely an issue, but if you're tinting an older classic, like a 60s Mustang or a vintage Bronco that came with a single driver-side mirror, you'd have to add a passenger-side mirror before tinting the rear window. We've actually had this come up on a restored Chevelle one of our Los Feliz customers brought in last fall.

Section 2: How RCW 46.37.430 actually gets enforced

Reading a statute is one thing. Knowing how it gets enforced on the side of I-405 in Bellevue at 7 a.m. is another thing entirely. Washington State Patrol troopers carry photometers, the little handheld tools that read VLT through the glass. If a trooper pulls you over for a routine reason, like a busted tail light or a speed infraction, and your tint looks too dark, they're allowed to measure it on the spot. They put the meter on the window, get a reading, and if it comes back under 24%, you get the citation. The fine varies by county but you're typically looking at $124 to $190 plus court costs in King County, and the ticket comes with a fix-it requirement.

What I want LA drivers to understand is the zero-tolerance posture. California is a 70% state on the front sides and CHP has historically been pretty inconsistent about enforcement, especially in LA. You can drive around Hollywood, Koreatown, or DTLA for years with 35% on the fronts and never get pulled over. Washington is not that. Seattle PD, Bellevue PD, and WSP all take tint enforcement more seriously, and the cultural expectation is that windows are lighter. If your car shows up in a Whole Foods parking lot in Kirkland with limo tint on the front doors, you stand out. You will be the darkest car in the lot by a wide margin. That visibility itself increases the chance of a stop.

I had a client last March, a producer who works out of an office near Sunset and Vine, who took a six-month assignment in Seattle and drove his blacked-out G-Wagen up. He had 20% all around, which is normal-dark by LA standards, almost stealthy by Beverly Hills standards. He got pulled over twice in his first three weeks, once in Tacoma and once on the way to Bellevue from the airport. We ended up stripping the front two and reinstalling at 35% which still measures around 27-28% combined on his factory glass, which is comfortably above the 24% Washington floor. Problem solved. He kept the rear and back at 20% because the G-Wagen is an SUV under Washington's classification, so the dark rear is fully legal.

Enforcement also matters at vehicle inspection if you move and register the vehicle in Washington. The state does not have annual safety inspections the way some states do, but if you get an emissions check in certain counties or if the car comes in for any service at a dealer who flags non-compliant tint, you can be required to bring the vehicle into compliance before reregistration. We've had clients get caught at that step too.

Section 3: The reflectivity rule nobody mentions until you get pulled over

Here's the rule almost nobody talks about, and it's the one that catches LA drivers off guard the most because we love a clean chrome look on certain builds. Washington caps tint reflectivity at 35% on every window. That means your film cannot reflect more than 35% of light back. In practical terms, no chrome film, no mirror finish, no overly metallic look. The old-school metalized films from the 90s and early 2000s frequently exceeded this. Modern ceramic films, including the XPEL PRIME lineup we install, are well under the 35% reflectivity cap because they don't use metal layers, they use ceramic nanoparticles for heat rejection. That's one of the reasons I steer dual-state clients toward ceramic.

Reflectivity matters more than people realize because at dawn and dusk, especially in the gray, low-angle light of a Seattle or Olympia winter, a reflective film can throw glare back at other drivers and at oncoming headlights. That's the safety reason the rule exists. The enforcement reality is that a trooper can ticket you on visual reflectivity even without a meter reading, because the chrome look is obvious. I've never seen a trooper carrying a reflectivity meter, but I've seen plenty of tickets written based on the visual call. If your windows look like sunglasses from the outside, you're in the gray zone.

California, for comparison, has a similar reflectivity rule but it's enforced almost never. Up in Washington, again, they actually do enforce it. If you've got a chrome-look film on a Tesla Model S that you put on at a shop in Mid-City or Echo Park three years ago and you're moving north, plan to have it replaced. We can spec out a non-reflective ceramic equivalent that gives you the same heat rejection without the legal exposure. Our installers in the shop typically recommend the XPEL PRIME XR Black for this scenario because the look is dark, sleek, and matte without any mirror tendency.

Section 4: Windshield, AS-1 line, and the strip at the top

The windshield rules are different from the side window rules in pretty much every state, including Washington. Washington allows non-reflective tint above the AS-1 line, which is a small etched marking near the top corner of every windshield manufactured for use in the US. If you've never noticed it, look at your windshield from inside the car right where the top edge meets the A-pillar. You'll see a tiny set of letters and numbers and one of them will say AS-1. That marking shows where the manufacturer has determined the boundary between the upper visor area and the main driver visibility zone.

In practical terms, that means you can put a tinted visor strip across the top of your windshield, typically four to six inches deep, and as long as it stays above the AS-1 line, it's legal in Washington. If the AS-1 line is not visible or your windshield does not have one for some reason (rare but it happens with certain replacement glass), the rule defaults to the top six inches of the windshield. The tint in that visor area still needs to be non-reflective, which again rules out chrome or mirror look films.

What you cannot legally do in Washington is run a full windshield tint, even a very light one like 70% ceramic. California allows clear ceramic on the windshield (the kind we install on a lot of our Hancock Park and Santa Monica clients' cars to cut heat without affecting visibility), but Washington's law does not have the same explicit clear-ceramic carve-out. If you ask me what I'd recommend for a dual-state owner, I'd skip the full windshield tint and stick with the legal visor strip. The trade-off is small and the risk of a citation is zero. For pricing on different VLT options, see our XPEL PRIME XR PLUS ceramic window tint page.

A quick note on heat. Most LA drivers who tint their windshield are doing it for thermal reasons, not for the look. The summer dashboard temperature in Koreatown or Mid-City can hit numbers that warp leather and crack screens. Washington doesn't have that problem outside of maybe two weeks in late July in Spokane and the inland east side. For most Seattle, Bellevue, Tacoma, and Olympia driving, the windshield can stay untinted and you won't notice a heat difference, especially with a quality ceramic on the side windows that handles the lateral sun load.

Section 5: Medical exemptions, what your doctor needs to write

Washington does provide a medical exemption from the 24% VLT rule. This is the route some of our clients take when they have lupus, severe photosensitivity, certain skin cancers, or eye conditions where direct sunlight causes real harm. The exemption is not automatic. You need a signed letter from a licensed physician, an optometrist, or an ophthalmologist that specifically states the medical necessity for darker than legal tint on the vehicle. The letter should reference the condition and explain why standard 24% VLT is insufficient.

You're required to keep the original signed letter in the vehicle at all times. If a trooper pulls you over and measures your tint at, say, 15% on the front sides, you present the medical exemption letter on the spot. The trooper will typically verify the doctor's signature and credentials and let you go. We've seen this work cleanly for many of our clients who relocate north with existing medical conditions. The letter does not need to be reissued annually unless the condition or doctor changes, though some troopers will look closely at the date so I'd suggest a renewed copy every two years for peace of mind.

California has its own medical exemption process and the two are not interchangeable. If you have a California medical exemption and you're moving to Washington, you need to get a Washington-recognized letter from a licensed practitioner. Your California letter does not transfer. Some doctors who practice in both states (we have a couple of dermatologists in Beverly Hills who actually maintain Washington licenses for telehealth purposes) can issue both, but most cannot. Plan ahead. We can recommend a couple of practices we've worked with that handle this paperwork cleanly.

The film we install on a medical exemption case is still ceramic, still non-reflective, just at a darker VLT. Usually 20% or 15% on the front sides with a medical exemption, sometimes 5% for the most severe cases. We label the install with a small sticker on the lower corner of the driver window indicating the medical install and we keep records of the install in case a trooper or insurance adjuster ever needs verification.

Section 6: California vs Washington at a glance

Here's the side by side that I draw on the whiteboard in our consultation area at the shop almost every week. California requires 70% VLT on the front two side windows. Yes, 70. That is what the California Vehicle Code 26708 spells out, and you can dig deeper into California window tint laws on our dedicated page. The rear side windows and back glass on a California car can be any darkness, including limo black. The windshield can have a four-inch strip of non-reflective tint at the top, or you can run clear ceramic across the whole windshield as long as it tests at 70% or higher. California also restricts reflectivity but enforces it loosely.

Washington requires 24% VLT on every window of a passenger car. Period. The SUV exception lets you go dark on the rear of a truck or SUV, but a sedan is locked at 24% front to back. Reflectivity is capped at 35% and enforced more strictly. Windshield strip is allowed above the AS-1 line, no full windshield tint. Medical exemption process exists but requires Washington practitioner letter kept in the vehicle.

The practical upshot for someone bouncing between LA and Seattle. Your sedan needs front-side tint between 24% and 35% to satisfy both states reasonably. Technically California wants 70% on the fronts, but the enforcement reality in LA for ceramic non-reflective film at 35% is functionally no problem in most neighborhoods, and 35% will pass cleanly in Washington. For an SUV or truck, you can run 24-35% front and any darkness on the rear and back, and you're legal in both states across the board.

I want to be honest here about the California front-window thing. Strict reading of the California Vehicle Code says 70% VLT minimum on the front sides. In practice, throughout our 30 years on Sunset Blvd, the enforcement of that 70% rule in Los Angeles has been inconsistent, especially when the film is non-reflective ceramic and the install is clean. We do, however, always recommend our clients install a California medical exemption when applicable and we install our standard front-window package at a VLT that is unambiguously legal in California for vehicles that have a documented exemption. For dual-state owners we discuss the full picture during consultation.

Section 7: XPEL film choices that work in both states

XPEL makes three main automotive window films we install at the Sunset Blvd shop. PRIME CS is the entry-level dyed ceramic, PRIME XR Black is the mid-tier carbon-ceramic hybrid, and PRIME XR PLUS is the flagship multi-layer nano-ceramic. All three come in 5%, 15%, 20%, 25%, 35%, 45%, 55%, and 70% VLT options. All three are non-reflective and well under the Washington 35% reflectivity cap. The differences are in heat rejection, infrared rejection specifically, clarity, and warranty.

For a dual-state passenger car (a Tesla Model 3, an Audi A4, a BMW 3 series, a Camry, an Accord), my recommendation is XPEL PRIME XR PLUS at 35% on all four side windows and the rear glass. That spec measures around 27 to 30 percent combined on most factory glass, which is above the Washington 24% floor with margin, and it's a non-reflective ceramic that looks great in LA and won't draw a trooper's eye in Seattle. The XR PLUS rejects around 98% of infrared heat, which matters more in Hollywood than in Olympia but doesn't hurt either way.

For a dual-state SUV or truck (a Tahoe, a Tacoma, a 4Runner, an X5, a Rivian R1S), I go XPEL PRIME XR PLUS at 35% on the front two and 20% or 15% on the rear sides and back glass. The front spec stays Washington-legal, the rear goes as dark as the owner wants because the SUV classification allows it. This is the build I do most often for clients who keep a primary residence in Pasadena or Glendale and a second home somewhere on the Eastside of the lake.

For someone who only drives in California and doesn't plan to cross the border, XPEL PRIME CS at 20% on the rear and 35% on the fronts is the affordable champion. It's not what I'd recommend for someone who needs to satisfy Washington law because the CS line has slightly less infrared rejection than XR PLUS, but it's still non-reflective and a strong value play for an LA-only daily driver in Echo Park or Koreatown.

One thing worth mentioning. All three XPEL automotive films carry a lifetime warranty against bubbling, peeling, fading, and delamination. We've had clients come back ten years after install with a perfect-looking install and a warranty claim on a minor edge issue, and XPEL stood behind it. That warranty transfers if you sell the car, which matters for resale value. If you want to see our XPEL services in full, that page covers everything from tint to PPF.

Section 8: What we recommend at our Sunset Blvd shop

When a client walks into the shop at 5300 Sunset Blvd and tells me they split time between LA and somewhere in Washington, my first question is always about the vehicle classification. Sedan or SUV. That single answer determines the recommendation more than anything else. The second question is about windshield. Do you want a heat-rejection strip at the top, or do you want a full clear ceramic? If they say full clear ceramic, I explain the Washington problem and we usually settle on the visor strip plus the clear ceramic only being installed if the car stays in California more than 80% of the time.

The third question is about timeline. We offer same-day window tinting in Los Angeles for most standard installs, which matters for the clients who fly in for a long weekend, drop the car off Saturday morning, and want to drive it back to Bellevue or Seattle Sunday afternoon. Our bay capacity on Sunset can handle four cars at a time for tint, and on a typical Saturday we'll process eight to twelve vehicles through the tint side of the shop. We also handle full XPEL paint protection film installs on the same site, so if you're doing both tint and PPF on the same visit, we coordinate that as one job.

Fourth question is about the daily driving environment. If you commute on the 405 between West LA and the Valley five days a week, your sun exposure is brutal and you need maximum infrared rejection. If you commute on I-5 between Tacoma and Seattle, your needs are completely different, more about glare management in low light and a film that doesn't get hazy in constant rain conditions. The XR PLUS handles both environments well, which is why I default to it for dual-state clients. The cheaper CS line is fine for the LA-only situation but starts to feel like a compromise once you're driving in Pacific Northwest gray weather a lot.

Last thing I always cover is what happens if you sell the car. The XPEL warranty transfers. The film typically adds resale value if it's been maintained, because the next buyer doesn't have to install. We give every client a printed install record with the film line, VLT percentages on each window, install date, and warranty registration. That paperwork lives in the glovebox and matters at resale time, especially in the Washington market where buyers are noticeably more conscious of tint legality.

Section 9: Pricing reality May 2026 in Los Angeles

Let me give you the actual price ranges as of May 2026 at our shop and at most reputable XPEL-authorized dealers across LA. For a standard four-door sedan, full XPEL PRIME CS install (four side windows plus rear glass) runs roughly $449 to $549. PRIME XR Black on the same sedan runs $649 to $799. PRIME XR PLUS, the flagship, runs $849 to $1,049 depending on glass complexity. Tesla Model 3 and Model Y, because of the panoramic rear glass and the larger surface area, are typically $100 to $150 above those base numbers.

For a two-row SUV like a 4Runner or a Tahoe, the surface area is bigger so the price scales up. Expect $549 to $649 for PRIME CS, $749 to $899 for XR Black, and $999 to $1,199 for XR PLUS. Three-row SUVs and full-size vans run higher, sometimes in the $1,300 to $1,500 range for the XR PLUS flagship build. We quote every job after a quick walk-around inspection so you get an exact number, not a range, before we touch the car. The fastest way to lock in a slot is to book your appointment online.

Windshield strip add-on, that legal four-to-six-inch visor we discussed earlier, is typically $99 to $149. Full clear ceramic windshield (California-only, not Washington-legal) runs $349 to $449 depending on glass curvature and rain sensor cutouts. We also offer commercial window tinting in Los Angeles for storefronts, offices, and warehouses, which is a different pricing structure entirely, but we mention it because we get questions from owners who have both a vehicle and a small business location in places like Highland Park, Atwater Village, or DTLA.

How does this compare to Washington shops? Honestly, prices in Seattle and Bellevue for the same XPEL lineup tend to run 10 to 20 percent higher than LA, partly because there are fewer XPEL-authorized dealers up there and partly because shop overhead is higher. We've had clients fly down to LA specifically to get tint done because the price difference more than covers the flight and hotel, especially on a higher-end vehicle getting both tint and PPF in one visit. Not for everyone, but it pencils for some.

Is 20% tint legal in Washington state?

No, 20% tint is not legal on the front side windows of any vehicle in Washington, and it is not legal anywhere on a passenger sedan. Washington requires 24% VLT minimum on the front sides of every vehicle and on every window of a passenger car. The only situation where 20% is allowed is on the rear side windows or back glass of an SUV, pickup truck, van, or multi-purpose vehicle, and only because the law permits any darkness on those rear positions for those vehicle classes. If you have 20% on a sedan in Washington, you are illegal and you will eventually get pulled over.

What's the darkest legal tint in Washington 2026?

The darkest legal tint on the front side windows of any vehicle in Washington in 2026 is 24% VLT. On the rear of an SUV, truck, van, or MPV, you can go as dark as you want, including 5% limo tint, with no legal upper limit on darkness. On the windshield, you can run a non-reflective tinted strip above the AS-1 line or the top six inches. With a valid medical exemption letter from a Washington-licensed physician or eye doctor kept in the vehicle, you can go darker than 24% on the front sides for documented medical reasons.

Do I need a medical exemption to tint front windows in Washington?

You only need a medical exemption if you want to go darker than 24% VLT on the front windows. If you stay at 24% or lighter, no exemption is required and you can install any non-reflective ceramic film at that VLT or above. If you have a condition like lupus, severe photosensitivity, certain skin cancers, or an eye disorder that requires darker tint, your doctor can write a signed letter stating the medical necessity. You keep that letter in the vehicle at all times and present it if a trooper measures your tint and finds it below 24%.

Can I keep my California 70% front-side tint when I move to Seattle?

Yes, you can absolutely keep California-spec 70% front side tint when you move to Seattle because 70% VLT is well above Washington's 24% minimum. In fact, lighter tint is always legal in Washington as long as reflectivity stays below 35%. The issue only arises if your California tint is darker than 24%, like a 20% or 15% spec, in which case you'll need to strip and replace the front-side film before driving in Washington. Many California drivers actually run 35% on the front sides for heat rejection, which is also Washington-legal and a clean dual-state spec.

How much does XPEL window tint cost in Los Angeles in 2026?

XPEL window tint in Los Angeles in 2026 runs from about $449 for a basic XPEL PRIME CS install on a standard sedan up to around $1,049 for the flagship XPEL PRIME XR PLUS install on the same sedan. SUVs and larger vehicles run $549 to $1,199 depending on the film tier. Add-ons like a windshield visor strip add $99 to $149, and full clear ceramic windshield runs $349 to $449 for California-only builds. At our shop on Sunset Blvd, we provide an exact written quote after a quick walk-around so you know the number before any work starts.

Final recommendation: stop guessing, book a consult

If you've read this far you already know more about Washington tint law than 90% of the drivers on I-5. The hard part is matching the law to your actual vehicle, your driving pattern, your sun exposure, and your aesthetic preference. That's a 20-minute conversation we have with every client at the shop, and you don't need to commit to anything to come in and have it. Bring your car, bring your questions about whether you split time between LA and the Pacific Northwest, and we'll spec out a film build that satisfies both states cleanly. We can also tell you what's not worth spending money on, which sometimes matters more than the upsell.

For LA-only drivers, we'll help you pick between PRIME CS for budget builds and XR PLUS for the highest heat rejection. For dual-state owners, we'll walk you through the 35% front, dark rear strategy on SUVs or the all-35% strategy on sedans. For anyone with a medical condition that warrants exemption documentation, we have referral relationships with practitioners in both states who handle the paperwork cleanly. We've been doing this on Sunset Blvd for three decades and we've seen every variant of the LA-to-Seattle, Bellevue, Tacoma, Spokane, Olympia, Redmond, and Kirkland migration story you can imagine.
