Since window tint laws vary from state to state, it is important to know the specific rules that apply to the state you live in. The state of Massachusetts window tint laws includes factors such as the level of tint darkness and which windows can be tinted. Being aware of the current MA tint laws can help you avoid costly fines that come with violations.

Purpose of MA window Tint Laws

The window tint laws for Massachusetts were passed in 1985. This type of law is in effect to assure the driver’s ability to see properly and for law enforcement to be able to see inside vehicles. Waivers are available for those who have a doctor’s certification that states that the driver needs added protection from the light. The laws only apply to aftermarket tint jobs since factory installed tinted windows meet federal standards. Coincidentally, these laws provide the benefit of protecting drivers and their car from hot weather, less glare and less damage to the car’s interior.

How Dark the Tint Can Be

The visible light transmission percentage is the measurement that determines how much light must be allowed to pass though the windows. Massachusetts law requires at least 35% of visible light must pass the rear, front side and back side windows. There has to be a couple of side mirrors on the vehicle if the rear window is tinted. Only the top 6 inches of the windshield can be tinted with non-reflective tint. The medical exemption is the only legal way to go above the set 35%.

How Reflective the Tint Can Be

Some tint jobs have small metal particles in them that can reflect some of the incoming light. While these particles reduce the amount of light that gets in the car, the mirror-like affect they can have is potentially dangerous for other drivers. To keep the tint at safe levels, there are regulations for how reflective they can be. The front side and back side windows cannot be more than 35% reflective.

Related Tint Standards and Rules

Unlike some other states, Massachusetts does not regulate what color tint you can have on car windows. You will also be able to have tint without sticker or certification proof of its legality. The state of Massachusetts does recommend you place a sticker on the car that identifies the tint as being legal. Manufactures of window tint film do not have to certify the film they sell in Massachusetts. Overall, this is one of the more lenient states in regard to tint regulations. The laws that are in place still need to be followed in order to protect others.

Massachusetts window tint laws help keep your fellow drivers and law enforcement safe, while allowing you to have tint on your windows for style or defense from the sun. The rules are easy to understand and do not place excessive restrictions on your tinting options. Your aftermarket tint can be as done as creatively as you would like, just as long as the appropriate amount of light is allowed to pass through it.
