Maryland Window Tint Laws (2026): Legal VLT Limits

In Maryland, all windows (front side, back side, and rear) on a standard passenger car must allow at least 35% visible light transmission (VLT). SUVs and vans with dual side mirrors may go darker on rear windows. Red, yellow, and amber tint colors are prohibited statewide.

What is the legal tint limit in Maryland?

Maryland's window tint rules are set out in Md. Code, Transportation 22-406. For standard passenger cars, the 35% VLT rule applies uniformly to the front side windows, back side windows, and the rear window. VLT stands for visible light transmission, the percentage of visible light a window allows through. A higher VLT percentage means lighter tint; a lower VLT percentage means darker tint. At 35%, Maryland sits in the middle range nationally.

SUVs and vans have a partial exception. If a multipurpose vehicle is equipped with dual side mirrors that give the driver an adequate rear view, the windows behind the driver may be tinted darker than 35%. The front side windows remain at the 35% minimum for all vehicle types without exception.

No measurement tolerance is specified in the Maryland statute, so the 35% figure should be treated as an exact floor.

Windshield tint rules in Maryland

Maryland permits tint on the windshield only in the top strip: above the AS-1 line or within the top 5 inches, whichever applies to your vehicle. Below that line, the windshield must remain free of any tint film.

In addition to the positional rule, Maryland prohibits reflective and mirrored finishes on any window. The state also bans specific tint colors: red, yellow, and amber are not permitted anywhere on the vehicle's glazing. These color restrictions apply to all windows, not just the windshield.

There is no listed percentage cap on reflectance in the statute, but the flat ban on reflective and mirrored finishes means any film that creates a mirror-like appearance is non-compliant.

Medical exemptions

Maryland law allows a medical exemption under Md. Code, Transportation 22-406(d). A driver or vehicle owner whose medical condition requires protection from sunlight or UV radiation may obtain an exemption by having a licensed physician provide written certification of the medical necessity.

Once you have the physician's written certification, you must carry it in the vehicle at all times. Maryland distinguishes between temporary and permanent conditions. An exemption based on a temporary condition is valid for up to two years; if the condition is permanent, the exemption may be issued indefinitely. Having the paperwork in the vehicle is critical because an officer or inspector will need to see it if the tint appears darker than the standard limits.

How tint is measured and certified

Maryland does not require a compliance sticker on tinted windows by statute. When an officer measures your tint, they will use a calibrated VLT meter. The reading is taken through the film and glass together; it is the combined transmittance that must meet the 35% minimum.

Because no tolerance is specified in the statute, avoid cutting it close. A film nominally rated at 35% may measure slightly below that on some vehicles depending on the factory glass tint. Ask your installer to verify the combined reading on your specific vehicle before you leave the shop.

If you have a medical exemption, carry that paperwork in the glove box. The exemption document substitutes for compliance with the standard VLT numbers.

Penalties for illegal tint in Maryland

Non-compliant window tint in Maryland results in a safety equipment repair order rather than a straightforward fine. The enforcement mechanism is tied to your vehicle registration: your registration may be withheld or held until the violation is corrected and the vehicle is re-inspected.

Because the primary consequence is a registration hold, the practical impact is significant. You cannot legally operate a vehicle with a suspended or withheld registration. Address a tint violation promptly by either removing or replacing the non-compliant film and scheduling a re-inspection.

If you want to tint your windows in Maryland

If you are planning to have aftermarket tint applied in Maryland, take these steps to stay compliant.

First, plan your VLT targets. For the front side windows, you need at least 35% VLT through the film and glass combined for any vehicle type. For a sedan, plan the same 35% minimum for the back side windows and rear window as well. If you drive an SUV or van with factory-fitted dual side mirrors, you have flexibility on the rear windows to go darker.

Second, confirm your factory glass. Most modern vehicles have factory glass in the 70-80% VLT range, meaning you can typically apply a film rated around 35-50% and still clear the combined 35% threshold. Your installer should measure your actual glass before selecting the film.

Third, verify the color of the film you are choosing. Maryland bans red, yellow, and amber tints. Stick to gray, charcoal, carbon, or ceramic films to avoid a color violation.

Fourth, skip the mirrored or metallic look. Reflective and mirrored finishes are prohibited in Maryland. If you want a premium appearance, ceramic or nano-ceramic non-reflective films comply with the state's rules while still offering heat and UV rejection.

Fifth, if you have a qualifying medical condition, see your physician for written certification before you have the tint applied. Keep the original certification in the vehicle so it is available at any inspection or traffic stop.
