window tint laws accept tints up to 6 inches from the top of your windshield. For additional windows—like the front sides, rear sides, and rear—tints may be applied up to 35%.

Tinted windows are an excellent way for drivers to personalize their vehicle, adding extra privacy and style. Too much tint can affect your visibility and the safety of other drivers, though, so each state has limits when it comes to darkening your windows.

What is the visible light transmission percentage?

The visible light transmission (VLT) percentage demonstrates how much light can pass through a window tint film. Each state has its own rules on this percentage.

A higher VLT means more light can pass through the window’s film. For example, a 45% VLT means 45% of the light can pass through your tint, while a 5% VLT only allows 5% of the light to pass through—meaning you can’t see into the vehicle whatsoever.

What is the Massachusetts window tint law?

The Massachusetts window tint law limits the degree to which you can tint your window—and is the same across most civilian vehicles. Here are the limits for Massachusetts:

Front windshield: Non-reflective (or metallic) at AS-1 line or up to 6 inches from the top of the windshield

Front-seat side windows: Up to 35% VLT

Back-seat side windows: Up to 35% VLT

Rear window: Up to 35% VLT

Reflective tint is allowed up to 35% VLT, but only on the front-side and back-side windows.

The Massachusetts window tint law has no requirements for what colors you tint your windows. Massachusetts drivers are also not required to have film certified by the manufacturer or identify their tint via a sticker—though having either can save you the hassle of explaining a questionable tint job if you’re pulled over.

This app is great, but the customer service is even better! Not to mention convenient! My husband and I got the lowest rate (much lower than the rates I was finding online through my own searches), quickly, and pretty much all through text message! Thank you so much for a hassle free experience👍

Medical exemptions

Massachusetts allows higher VLTs on the grounds of medical exemption. Applications are initially-determined and signed by a physician, then sent to the Massachusetts Medical Advisory Board—where exceptions are processed and decided.

If accepted, those granted the exemption will be sent a large sticker that must be displayed on the driver side window (directly next to the driver) at all times.

Penalties for violating the window tint law

If you’re pulled over for violating Massachusetts Window Tint Law, you’ll be charged a $250 fine.
