Massachusetts Tint Law

Massachusetts is among the first U.S. states to enforce window tint laws. These laws were first enacted in 1985.

Getting your windows tinted surely adds to the visual appeal of your car. But it also offers several other advantages, such as temperature control, blocking out UV rays; and protecting your interior from fading and cracking.

But window tinting comes along with certain restrictions that help keep drivers and other drivers safe. These rules and regulations are stipulated by the Massachusetts tint laws.

So, before you go ahead and get your vehicle’s windows tinted, it is a good idea to familiarize yourself with the tint laws of the state.

However, with new types of window tint films entering the market along with different installation techniques, the tint laws of Massachusetts have undergone several changes over the years.

With that in mind, it’s really important that you know and understand these laws. Below we go into some of the details.

Permitted Window Tint Darkness

The most regulated aspect of window tint is how dark your tint film can be. This is something that can be measured in terms of VLT or visible light transmission.

It’s a unit that refers to the amount of ambient light that can pass through the tint film. The lower the VLT, the darker the tint and vice versa.

For example, if a window tint has a VLT of 35%, it essentially means that only 35% of light coming to your window can pass through the tint film.

Below you’ll find the permitted window tint darkness in Massachusetts for different types of vehicles.


Windshield: The windshield can have a 6″ stripe of non-reflective tint above the AS-1 line.
Driver-side windows: 35% VLT required.
Passenger-side windows: 35% VLT required.
Rear window: 35% VLT required.

Acceptable Tint Reflection

Massachusetts also has laws governing how reflective your car windows should be.

Tint reflection is basically how much light is reflected by the window tint, whereas, window tint darkness or VLT is the amount of light that is allowed in by the tint.

Reflective window tints can help reduce the glare inside your car. However, if they’re overly reflective, it can be very distracting for other vehicles on the road.

Whether you drive a sedan, an SUV, or a van, your window tint should not be over 35% reflective.
