When you’re cruising down the Massachusetts Turnpike in your newly tinted ride, you might think you’re all set – but are you actually compliant with the state’s window tinting laws? For instance, did you know that sedans, SUVs, and vans require at least 35% light transmission through front, back, and rear side windows?

That’s just the tip of the iceberg, as there are also rules about reflection limits, certification stickers, and medical exemptions. You’ll want to get familiar with these regulations to avoid fines and penalties – but where do you even start?

Massachusetts Window Tinting Laws

Window Tint Darkness Regulations

In regards to window tint darkness regulations in Massachusetts, there are specific rules regarding the visible light allowed through your vehicle’s windows.

For sedans, SUVs, and vans, you’re required to have more than 35% of light transmission through your front, back, and rear side windows. This means you can’t have extremely dark tints, like a 5% VLT, which would block most of the light.

Instead, you should opt for tints with higher VLT numbers, like 95%, which allow more light to pass through. Additionally, your windshield can have non-reflective tint on the AS-1 line or top 6 inches, but this doesn’t affect the overall tint darkness regulations.

Window Tint Reflection Limits

While verifying your vehicle’s window tint adheres to Massachusetts’ darkness regulations, it’s just as vital to comply with the state’s reflection limits.

Massachusetts window tint rules permit a maximum of 35% reflective window tint on front and back side windows to reduce glare and heat. This limit is in place to guarantee safe driving conditions and prevent excessive glare, which can impede your visibility and compromise road safety.

Failure to comply with window tint reflection limits can result in fines up to $250 for non-compliance with window tint laws. As you navigate Massachusetts roads, it’s essential to prioritize window reflection limits to avoid penalties and maintain a safe driving environment.

Other Massachusetts Window Tint Rules

You’ll need to comply with additional requirements in Massachusetts, including the use of dual side mirrors if your window tint is too dark.

You’ll also need to obtain certification for your window tint, which involves getting a sticker that proves your tint meets the state’s standards.

Dual Side Mirrors Required

Massachusetts drivers must equip their vehicles with dual side mirrors if they plan to install window tints with a VLT (visible light transmission) of less than 35% on the back windshield and rear side windows.

This regulation guarantees you have an unobstructed view of the road behind you, as the tinted windows may reduce your reflection visibility. The dual side mirrors provide an additional means of checking your blind spots, allowing you to drive safely.

Failure to comply with this law may result in fines or penalties. Make certain to install dual side mirrors before applying dark window tints to avoid any issues with Massachusetts window tint laws and regulations.

Certification and Stickers

In addition to meeting the dual side mirror requirement, Massachusetts drivers must also guarantee their window tints comply with certification and sticker regulations.

You’re required to obtain a certification sticker from the installer or manufacturer, which must be placed on the driver’s side window. This sticker identifies the window tint as legal in Massachusetts.

You won’t need a permit, but you must verify the tint reflects no more than 35% of visible light. Certain exemptions apply, such as for medical conditions, but you’ll need to provide documentation to prove your eligibility.

It’s essential to understand that only permitted window tints are legal in Massachusetts, so make sure to certify compliant products and installers to avoid any issues.

State of Massachusetts Information

Since 1985, Massachusetts has enforced strict regulations on window tinting, aiming to guarantee road safety while allowing for some level of customization.

As a Massachusetts resident, you should be aware of these laws to verify your car windows, including those on your SUV, comply with the state’s regulations.

The Visible Light Transmission (VLT) percentage is vital, as it determines how much light can pass through your window tint. You’re allowed a VLT of 35% on the front side windows and 25% on the rear and back side windows.

Medical exemptions are available, but you’ll need to obtain a written statement from a medical professional.

Law enforcement takes these regulations seriously, so it’s essential to follow Massachusetts’ window tint laws to avoid penalties.
