Understanding the Tinting Laws in Massachusetts

The Darkness Limit for Window Tinting

Regarding the maximum level of window tinting darkness, Massachusetts has specific regulations. The amount of light that can travel through the tint film is used to gauge compliance with these rules.

To preserve visibility and guarantee the safety of both motorists and pedestrians, it is important to follow these limitations.

Massachusetts law mandates that the tint film on the front side windows let at least 35% of light flow through. This indicates that no more than 35% of the color should be dark.

On the other hand, the rear window and the rear side windows may both have any shade of dark tint.

Windshield Tinting Regulations

The particular rules for windshield tinting are likewise detailed in the Massachusetts window tinting laws. The only exception allowed by the law is a non-reflective strip running along the top of the windshield.

This strip shall not extend more than six inches below the AS-1 line or the top of the windshield, whichever comes first. It is important to remember that this strip should be clear and not hamper the driver’s vision.

Medical Exemptions for Window Tinting

For those who need window tinting for medical reasons, Massachusetts law offers several exemptions. You can be qualified for a medical exemption if your health requires more protection from the sun’s damaging UV rays or hot weather.

You need a certificate from a qualified doctor, ophthalmologist, or optometrist to be eligible for a medical exemption.

The appropriate amount of darkness and the medical condition that required window tinting should be included in this document. When asked by law enforcement, the certificate must always be kept in the automobile and produced.

Penalties for Non-Compliance

Penalties and fines may apply if Massachusetts window tinting regulations are broken. You risk receiving a penalty and being forced to remove or adjust the tint film if the windows of your car don’t satisfy the legal requirements for darkness or if they break any other legal rules.

The severity of the breach and past offenses may affect the penalties for non-compliance. It’s important to remember that businesses or people that tint windows illegally risk punishment as well.
