Understanding the Terminology Regarding Tint Laws

The most important part of the legislation is understanding what VLT is and how law enforcement services check or test the percentage.

What is VLT

VLT, or Visible Light Transmission, is a measure of the amount of visible light that can pass through a window tint or film. It is commonly used to determine the darkness or opacity of window tints, and it’s an important factor in window tinting laws and regulations.

VLT is typically expressed as a percentage. For example, a window tint with a VLT of 20% allows only 20% of visible light to pass through, making it relatively dark and less transparent. Conversely, a window tint with a VLT of 70% allows 70% of visible light to pass through and is much lighter and more transparent.

How do Law Enforcement services test the VLT percentage?

Window tinting laws vary by jurisdiction, and they often specify the maximum allowable VLT for different types of windows on a vehicle, such as the front windshield, front side windows, rear side windows, and rear window. These laws are designed to ensure that drivers have adequate visibility and that law enforcement can see into vehicles for safety and identification purposes. The manner that they go about testing the VLT is by using a VLT gauge/meter.

Here is a YouTube Short from @TrafficServices and @TorontoPolice showcasing the device and how it works. Even though it is in Canada, it still is helpful to understand how the tint darkness is measured.

Window Tint Darkness in Massachusetts:

The basis for Massachusetts’ regulations revolves around Visible Light Transmission (VLT), indicating the percentage of visible light that must be allowed through car windows. These specifications vary for sedans and SUVs/vans.

Massachusetts Car Tint Laws For Sedans:

  • Windshield: Non-reflective tint is permissible on the AS-1 line or the top 6 inches of the windshield. However, the law does not specify a particular VLT percentage.
  • Front Side Windows: These windows must allow more than 35% of light in, ensuring sufficient visibility.
  • Back Side Windows: The law requires back side windows to permit more than 35% of light, balancing privacy and safety.
  • Rear Window: Similar to back side windows, the rear window must allow more than 35% of light transmission.

Tint Laws For SUVs and Vans in Massachusetts:

  • Windshield: Non-reflective tint is permitted on the AS-1 line or the top 6 inches of the windshield, but the law does not specify a particular VLT percentage.
  • Front Side Windows: Front side windows on SUVs and vans must allow more than 35% of light, maintaining visibility and safety.
  • Back Side Windows: The law allows “any darkness” on back side windows without specifying a particular VLT percentage.
  • Rear Window: SUVs and vans can also use “any darkness” on the rear window as long as it complies with the law.

Window Tint Reflection in Massachusetts:

Tinted windows can reduce glare and heat by reflecting incoming light. Massachusetts law allows a specific level of light reflection.

Tint Reflection for Sedans and SUVs/Vans:

  • Front Side Windows: The law mandates that front side windows must not be more than 35% reflective, although it does not provide a specific definition of “reflective.”
  • Back Side Windows: Similar to front side windows, back side windows must not be more than 35% reflective without further clarification.

Additional Massachusetts Window Tint Rules and Regulations:

Massachusetts’ regulations encompass various other important aspects:

Side Mirrors

Dual side mirrors are obligatory if the back window is tinted, ensuring drivers maintain proper visibility.

Restricted Colors

Massachusetts does not explicitly prohibit specific auto tint colors, allowing flexibility in tint color choice.

Certificates

Film manufacturers are not required to certify the film they sell in the state, but vehicle owners should confirm that their film complies with state law.

Stickers

While not obligatory, state law recommends the use of stickers to identify legal tinting.

Medical Exceptions

Massachusetts permits medical exemptions for special tint. The terms and conditions of these exemptions are detailed in state law.

Regulations for Out-of-State Drivers

The same regulations apply to out-of-state drivers as those for drivers living in the State.
If you are from States such as Rhode Island, Connecticut, New York, Vermont, and New Hampshire, you are expected to abide by these laws and regulations.

Penalties

Non-compliance with tint regulations may result in fines of up to $250. Third or subsequent convictions can lead to a 90-day driver’s license suspension.

It’s essential to recognize that interpretations of Massachusetts’ tinting laws may differ depending on your county or local jurisdiction. For complete compliance, always double-check the information with your local Department of Motor Vehicles (DMV) or consult with law enforcement authorities.
