Other MASS Window Tint Rules and Regulations:

When it comes to window tinting in Massachusetts, the state has established a comprehensive set of rules and regulations to ensure safety on the roads. In addition to adhering to specific darkness and glare percentages for each window, there are several other guidelines you’ll need to follow as well. From the positioning of the tint to the types of materials allowed, it’s important to be well-informed to avoid any potential fines or legal issues. So, before you move forward with tinting your vehicle’s windows, make sure to review all of the applicable rules and regulations. Read on to learn more about the additional requirements for window tinting in Massachusetts.

Side Mirrors: In MA, it is mandatory for vehicles to have dual side mirrors if the rear window is tinted. This regulation is in place to ensure the safety of all drivers on the road. The side mirrors are an important safety feature as they provide the driver with a clear view of the vehicles behind and on the sides of the car. Without this view, it would be difficult for the driver to gauge the distance and speed of the other vehicles, making it challenging to make safe lane changes or merge onto the highway. Additionally, side mirrors are also crucial in helping drivers to safely back up and park their vehicles. By requiring dual side mirrors, Massachusetts is ensuring that all drivers on the road have the necessary tools to drive safely and avoid accidents.

Restricted Colors: In MA, there are no restrictions on the specific colors that can be used for auto tint. This means that drivers are free to choose any color they prefer for their car’s tint, as long as it adheres to the state’s laws regarding the amount of tint that is allowed on the windows. The state regulates the amount of light that can pass through the tinted windows, rather than the color of the tint itself. This allows for more flexibility for drivers and allows them to personalize their vehicles to their preferences without worrying about breaking the law. However, it’s important to note that even though the state does not restrict the color of the tint, it’s still important to comply with the laws regarding the amount of tint allowed on the windows, as it’s put in place to ensure the safety of the drivers on the road.

Certificates: In MA, manufacturers of film are not required to certify the film they sell in the state. This means that there is no requirement for manufacturers to provide any documentation or proof that their film meets the state’s standards for legal tinting.

Stickers: Massachusetts State law recommends but does not require stickers to identify legal tinting. This means that manufacturers or installers may choose to apply a sticker to the tinted windows to indicate that the tint has been installed in compliance with the state’s laws. This can serve as a helpful reference for law enforcement officers, but it is not mandatory.

Medical Exceptions: MA does permit medical exemptions for special tint. These exemptions are intended for individuals with certain medical conditions that require a specific level of tint on their car windows. For more details about the specific terms of the exemption, consult your state law.

Penalties For Non-Compliance: Penalties for violating tinting laws in Massachusetts can include fines of up to $250 for a first offense. Third or subsequent convictions will result in 90-day driver’s license suspension. It’s important to comply with the state’s laws regarding tinting to avoid penalties and ensure the safety of all drivers on the road.
