Maryland Window Tint Laws 2026: Legal Limits by Window and Vehicle
Maryland window tint laws set a 35% light transmission limit, and it covers every window on a passenger car. SUVs, vans, and light trucks face that limit only beside the driver, so rear windows can go darker. The exceptions decide which films pass inspection.
At Capital Wrappers in Rockville, MD, drivers ask these questions before choosing a shade. This guide checks each rule against the Transportation Article and COMAR, covering windshields, colors, repair orders, and waivers. Each limit names its legal source, so drivers can verify it themselves.
What Is the Legal Window Tint in Maryland in 2026?
Maryland requires at least 35% light transmission through any window covered by the rule, after the film is applied. The legal source is Transportation Article §22-406(i), and the same 35% figure appears in COMAR 11.14.04.16.
Which windows the rule covers depends on how the vehicle is registered. The table below shows the result for the most common vehicle types.

How Does the 35% Rule Work on Each Window?
The 35% figure is the final reading on the finished window, not the rating printed on the film. Factory glass already blocks some light, so a 35% film often reads lower once it is installed.
Inspection stations measure each regulated window with a state-approved tint meter. The statute says at least 35%, so a reading of exactly 35% is legal.
Before recommending a shade, Capital Wrappers takes a glass reading so the final result stays inside the legal limit.
What Are the Rules for Passenger Cars and Station Wagons?
Passenger cars and station wagons, registered as Class A vehicles, must keep at least 35% light transmission on every window. That includes the front sides, rear sides, and rear window.
No window on these vehicles can read below 35%, so 5% and 20% films are illegal on every window.
What Are the Rules for SUVs, Vans, and Light Trucks?
Multipurpose passenger vehicles, which include most SUVs and minivans, register as Class M. For these vehicles, the 35% rule applies only to the windows beside the driver, meaning the front side windows.
Rear side windows and the rear window may go to any darkness, provided outside mirrors sit on both sides. Light trucks of ¾ ton or less register as Class E, and the statute applies the same beside-the-driver rule.
COMAR sets separate rules for trucks, buses, and limousines, so pickup owners should confirm their registration class before ordering film. Capital Wrappers can review the registration and recommend a legal shade.
Can Drivers Tint the Front Windshield in Maryland?
Maryland allows film on the windshield only above the AS-1 line or within the top 5 inches, whichever is smaller. The AS-1 line is a marking printed near the top of the windshield glass.
Full-windshield tint is not legal, and a medical exemption does not change that boundary. A sun strip above the line is the legal way to cut glare.
Are 5%, 20%, 35%, 50%, and 70% Tint Legal in Maryland?
Film ratings describe the film alone, while the law measures the finished window. A 35% film on factory glass often reads below 35%, so 50% and 70% films often pass where 35% fails.

Pickups and other light trucks depend on registration class, so a meter reading and a registration check come first.
A glass reading shows which shade will pass Maryland’s 35% rule before any film goes on. Rockville drivers can call (301) 417-5977 for a reading and a vehicle-specific shade recommendation. The quote lists the film, the expected reading, and the legal limit.
Which Tint Colors and Finishes Are Illegal in Maryland?
Maryland bans red, yellow, and amber film on any window or windshield, along with film that changes to those colors. Mirrored, one-way, and sparkling finishes are also prohibited under COMAR 11.14.04.16.
Ceramic and carbon films are not exempt. Both are legal when the finished window meets the limit and the finish is not mirrored.
Neither the statute nor COMAR sets a reflectivity percentage. Older guides cite a 35% reflectivity allowance, and that figure does not appear in current Maryland law.
Is Window Tint a Primary Offense in Maryland?
Tint can be enforced on sight. An officer who observes a violation may stop the driver and issue a citation and a repair order.
A stop still requires a likely violation the officer can see. Borderline film carries more risk than film that clearly passes. Fine amounts vary by charge, and the statute sets no single figure.
What Happens After a Tint Repair Order?
A safety equipment repair order, or SERO, gives the owner 10 days to correct the defect. Tint violations are recorded as defect #61 on Maryland State Police forms.
After the correction, an authorized inspection station tests each regulated window with a state-approved meter and records pass or fail.
Maryland’s rules call for registration suspension when an owner misses the 30-day compliance deadline. The registration is restored once satisfactory evidence shows the equipment was corrected.
How Does a Maryland Tint Waiver Work?
A Maryland tint waiver is a medical exemption for people who must be protected from the sun. It requires a written physician certification on the Maryland State Police form, and the certification must stay in the vehicle. The person who needs the protection does not have to be in the car, as long as the certification is.
Since October 1, 2025, temporary certifications last as long as the physician sets, with no two-year cap. A certification for a permanent condition is valid indefinitely.
The waiver does not override windshield, color, or equipment rules, and it covers only the listed owner. Some older summaries still cite the two-year limit that the 2025 law removed. The form is issued by the Maryland State Police Automotive Safety Enforcement Division.
Is Removable Tint for a Child Under 10 Legal?
Maryland exempts easily removable tint used to protect a child under 10 from the sun. Static-cling shades are a common example.
Permanent film does not qualify, so aftermarket tint still has to meet 35% unless a waiver applies.
Are Tinted Tail Lights Illegal in Maryland?
Tail light covers are a lighting equipment question, separate from the window tint rules above.
Covers that dim or change the color of required lamps can draw a repair order or fail inspection. Drivers should confirm with Maryland State Police or an inspection station before installing any cover.
Does Maryland-Legal Tint Stay Legal in D.C. and Virginia?
Maryland-legal tint can fail in D.C. or Virginia, because each sets its own limits. Drivers who cross the line should check both before choosing a shade.
A shade chosen at the Maryland minimum may leave little margin elsewhere. Commuters should compare rules before installation.
How Can Drivers Choose Legal Film Without Giving Up Heat Rejection?
Heat rejection comes from the film technology, not only from darkness. Ceramic and carbon films can reject infrared heat at lighter shades, and both follow the same 35% rule.
Drivers should ask for the film’s published heat and UV numbers at the installed shade. A written final reading for each regulated window is also worth requesting.
Where Do These Maryland Tint Rules Come From?
Every limit in this guide comes from official sources. The Maryland Transportation Article §22-406 sets the 35% rule, the enforcement process, and the medical exemption.
COMAR 11.14.04.16 adds the vehicle-class details, banned colors, and mirror requirements. Chapter 452 of the 2025 laws, effective October 1, 2025, changed how long medical certifications last.
Maryland State Police forms and inspection reports provide the inspection and exemption procedures. This guide is general information, not legal advice, and laws can change.
Final Thoughts on Maryland Window Tint Laws in 2026
Maryland window tint laws come down to a 35% final reading, with the vehicle class deciding which windows it covers. Passenger cars follow it on every window, while SUVs, vans, and light trucks follow it beside the driver. Windshield, color, and medical rules apply on top.
Drivers who cross into D.C. can compare D.C.’s window tint laws before choosing a shade. Capital Wrappers serves Rockville, Gaithersburg, North Bethesda, Potomac, Aspen Hill, and Derwood, and checks the glass reading on every vehicle.
Choosing a legal shade starts with the vehicle class and the glass reading. Capital Wrappers will measure the glass, explain which films pass Maryland’s 35% rule, and quote the install. Call (301) 417-5977 to book a window tint consultation in Rockville.
Frequently Asked Questions
What is the darkest legal window tint for a passenger car in Maryland?
The darkest legal tint for a passenger car in Maryland is whatever reads at least 35% light transmission on the finished window. That limit applies to every window, so 5% and 20% films are illegal. Factory glass lowers the reading, so 50% or 70% film often passes where 35% film fails.
Is 20% window tint legal on an SUV in Maryland?
Twenty percent film is illegal on the front side windows of an SUV, because those windows must read at least 35%. It can be legal on the rear side windows and rear window of a multipurpose vehicle, provided outside mirrors sit on both sides. Confirm the vehicle’s registration class first.
Can Maryland police pull a driver over only for dark window tint?
An officer who observes a tint violation may stop the driver and issue a citation and a repair order. The stop still depends on what the officer can reasonably observe, so borderline film carries more risk. The owner then has 10 days after the repair order to correct the defect and pass inspection.
How do I get a medical window tint exemption in Maryland?
A physician completes the Maryland State Police certification form, and the original stays in the vehicle. Since October 1, 2025, temporary certifications last as long as the physician sets, and permanent conditions are indefinite. The waiver never allows tint below the AS-1 line.
Is 5% tint legal on the back windows of an SUV in Maryland?
Five percent film can be legal on the rear side windows and rear window of an SUV, because the 35% rule applies only beside the driver. COMAR requires outside mirrors on both sides when side or rear tint is present. Front side windows must still read at least 35%, so confirm the class first.
Are tinted tail lights legal in Maryland?
Tail light covers fall under vehicle lighting equipment rules, not the 35% window tint rule. Covers that dim or change the color of required lamps can draw a repair order or fail inspection. Check with Maryland State Police or an inspection station before installing any tail light cover.
