Maryland's legal tint limits for passenger vehicles
Maryland allows window tinting on passenger cars, but the law sets specific darkness limits for each window. The darkness of tint is measured by Visible Light Transmission (VLT), which is the percentage of light allowed through the glass and tint combined. A lower VLT percentage means darker tint.
For passenger vehicles in Maryland, the front side windows must allow at least 35% of light through, the rear side windows can be any darkness, and the rear windshield can be any darkness. The windshield itself cannot have tint except for a non-reflective strip along the top, typically no more than 5 inches down from the top of the glass. These rules explore to sedans, coupes, and most standard cars registered in Maryland.
Reflective or mirrored tint is not permitted on any windows. The tint must also be a single color and cannot have patterns or designs. If your windows are tinted darker than the legal limit, you can be stopped by law enforcement and issued a citation.

Medical exemptions for darker tint
Maryland allows medical exemptions for window tint that exceeds the standard legal limits. If you have a medical condition that requires protection from sunlight — such as lupus, porphyria, or severe photosensitivity — you may be able to have darker tint on your vehicle.
To obtain a medical exemption, you must have a letter from a licensed physician stating that you have a medical condition requiring UV or light protection. You then submit this letter along with your vehicle registration to the Maryland Motor Vehicle Administration (MVA). The MVA will issue you a medical exemption certificate that you keep in your vehicle.
With a valid medical exemption certificate, you can have tint darker than the 35% front window limit. However, you must still follow all other rules: no reflective tint, no patterns, and the windshield strip limit remains the same. Law enforcement can ask to see your exemption certificate if they stop you, so keep it accessible in your vehicle.
Tint rules for SUVs and trucks
SUVs and trucks have different tint rules than passenger cars in Maryland. For these vehicles, the front side windows must allow at least 35% of light through, just like passenger cars. However, the rear side windows and rear windshield can be any darkness without restriction.
This difference exists because SUVs and trucks typically have rear windows that do not face other drivers on the road in the same way passenger car windows do. The windshield rules remain the same for all vehicles: no tint except for a non-reflective strip at the top, no more than 5 inches down.
What happens if your tint is too dark
If a police officer stops you and determines your window tint is darker than Maryland law allows, you will receive a citation. The violation is typically classified as a non-moving violation, similar to an equipment violation. The fine amount varies but is generally between $50 and $100, though the exact amount can depend on the officer's jurisdiction and whether you have prior violations.
You have the option to contest the citation in court if you believe your tint is within legal limits. You can bring documentation of your tint's VLT percentage if you had it professionally measured. Some people choose to have the tint removed or lightened to comply with the law rather than go to court.
If you receive multiple citations for illegal tint, the fines can accumulate, and you may face additional penalties. It is generally less expensive to have your tint adjusted to meet legal requirements than to pay repeated citations.
How to measure your tint darkness
If you are unsure whether your current tint meets Maryland's legal limits, you can have it professionally measured. Many window tint shops and some automotive service centers have a tint meter that measures the VLT percentage of your windows. This measurement tells you exactly how much light is passing through your tinted windows.
You can also request that a tint shop measure your windows before you have new tint installed. This ensures that the new tint will be within legal limits. Professional tint installers in Maryland are familiar with state law and can install tint that meets the 35% front window requirement.
If you are having tint installed, ask the shop to provide documentation of the VLT percentage. This documentation can be helpful if you are ever stopped by law enforcement, as it proves your tint is legal. Keep this paperwork in your vehicle along with your registration.
Tint rules for commercial vehicles
Commercial vehicles registered in Maryland have the same tint rules as passenger cars and trucks. The front side windows must allow at least 35% of light through, and the rear windows can be any darkness. The windshield rules are identical: no tint except for a non-reflective strip at the top.
If you operate a commercial vehicle in Maryland, you should verify that your tint meets these requirements. Commercial vehicles are subject to the same enforcement as personal vehicles, and citations can affect your driving record and insurance rates.
Frequently Asked Questions
Can I have completely dark tint on my rear windows in Maryland?
Yes. Maryland law allows rear side windows and rear windshields to be tinted to any darkness level. Only the front side windows are restricted to a minimum of 35% light transmission. Many people choose to have darker tint on rear windows for privacy while keeping front windows within the legal limit.
What is the penalty for having illegal window tint in Maryland?
A citation for illegal window tint is typically a non-moving violation with a fine between $50 and $100, depending on your jurisdiction. You can contest the citation in court if you believe your tint is within legal limits. Repeated violations can result in higher fines and may affect your driving record.
Do I need a medical exemption letter from a specific type of doctor?
The letter must come from a licensed physician. This includes MDs and DOs (doctors of osteopathic medicine). The letter should state that you have a medical condition requiring UV or light protection. Once you submit the letter to the MVA, you will receive an exemption certificate to keep in your vehicle.
Can I have tint with a design or pattern on my windows?
No. Maryland law requires that tint be a single solid color with no patterns or designs. Reflective or mirrored tint is also illegal. Your tint must be uniform across the window and cannot have any decorative elements.
What if I move to Maryland with a vehicle that has legal tint in another state?
You must comply with Maryland's tint laws once you register your vehicle in the state. If your tint is darker than Maryland allows, you will need to have it removed or lightened to meet the 35% front window requirement. Law enforcement can cite you for illegal tint regardless of where the tint was originally installed.
