The direct answer
Massachusetts generally requires regulated side and rear glass with aftermarket tint to maintain at least 35% total visible light transmission, or VLT. It also limits visible light reflectance to no more than 35%. Standard windshield material is limited to the uppermost six inches and may not enter the driver's direct forward viewing area.
Rhode Island generally requires at least 70% total VLT on the windshield, side windows, and rear window of a passenger vehicle. Eligible trucks, buses, campers, multipurpose passenger vehicles, and other listed classes can use sunscreen material on windows behind the driver when two compliant outside mirrors provide a clear rear view.
Most important: The percentage printed on the film is not the final legal reading. The glass and film are measured together.
Two states. Different rules.
| Question | Massachusetts | Rhode Island |
|---|---|---|
| Standard passenger-vehicle VLT | At least 35% total VLT on regulated side and rear glass | At least 70% total VLT on windshield, side windows, and rear window |
| Windshield | Transparent material limited to uppermost 6 inches and direct-view limits | At least 70% total VLT, plus a transparent uppermost 6-inch strip exception |
| Rear glass on SUVs and trucks | No broad SUV or truck darkness exception stated in Section 9D | Eligible listed vehicles may use sunscreen material behind the driver with two compliant outside mirrors |
| Medical exemption | RMV waiver for eligible private passenger vehicles; windshield remains restricted below AS-1 | DMV exemption may allow darker windows; it does not apply to the windshield |
| Maximum statutory fine | Up to $250; third or later conviction carries a license-suspension provision of up to 90 days | Up to $250 for the vehicle owner |
This comparison is a starting point. Registration, vehicle classification, glass position, factory equipment, mirror configuration, measured VLT, and approved exemptions can change the answer.
Understand the meter
VLT is the percentage of visible light passing through the tested glass and film. Factory automotive glass already reduces visible light, so adding film produces a lower combined reading than the film's nominal percentage.
The formula is an estimate. Manufacturing tolerance, film batch, glass construction, coatings, meter calibration, curved glass, and test conditions can change the reading. A calibrated VLT meter on the vehicle is the practical compliance check.
A film labeled 35% will normally measure below 35% when installed on automotive glass. A light or near-clear film can also reduce a Rhode Island window below the state's 70% total threshold.

Massachusetts General Laws Chapter 90, Section 9D prohibits window treatments that make regulated glazing nontransparent or obscure the view, then provides exceptions for compliant sunscreen material and listed vehicles.
35% minimum total VLT on regulated side and rear glass.
35% maximum visible light reflectance. Reflectance and light transmission are different measurements.
Massachusetts does not inherit Rhode Island’s behind-driver vehicle-class exception.
| Glass Position | Standard Massachusetts Rule | Important Detail |
|---|---|---|
| Windshield | Transparent material only within uppermost 6 inches | Cannot enter the driver's direct forward viewing area; RMV guidance also references the AS-1 line |
| Front side windows | At least 35% total VLT | Glass and film are measured together |
| Side windows behind front seats | At least 35% total VLT under the standard film exception | Do not assume an SUV or truck receives Rhode Island's broad rear-glass class exception |
| Rear window | At least 35% total VLT under the standard film exception | Two outside mirrors must provide a clear view behind |
| Visible light reflectance | No more than 35% | Mirror-like appearance can create a separate issue |
Section 9D also contains exceptions for qualifying factory glazing, certain law-enforcement and security vehicles, out-of-state registrations, specified public-livery rear glass, approved medical waivers, and certain rear-window treatments when mirror requirements are met.
Read Massachusetts General Laws, Chapter 90, Section 9D ↗Massachusetts · Windshield
Not under the standard Massachusetts rule. Section 9D allows transparent material limited to the uppermost six inches, provided it does not enter the driver's direct forward viewing area. RMV guidance refers to the AS-1 line in this upper area.
The Massachusetts RMV states that a tinted-glass medical waiver permits additional tinting on front side, rear side, and rear windows only. It does not authorize windshield tint below the AS-1 line or uppermost six inches.
Quick answer: A light or near-clear full-windshield film is still not automatically legal in Massachusetts. Film darkness does not replace the glass-location rule.
Massachusetts · Medical waiver
The Massachusetts RMV may issue a tinted-glass waiver for an eligible private passenger vehicle when a physician certifies that the owner or insured operator is photophobic or photosensitive and needs additional tinting.
Massachusetts · Inspection & penalties
Yes. Massachusetts requires registered vehicles to pass a yearly inspection, and licensed inspection stations are required to have a tint meter. Noncompliant aftermarket tint can result in an inspection rejection and may need to be removed or replaced before the vehicle passes.
Official MA vehicle inspection information ↗Massachusetts General Laws Chapter 90, Section 9D authorizes a fine of up to $250. On a third or subsequent conviction, Section 9D provides for license suspension for up to 90 days.

Rhode Island · Passenger vehicles
Rhode Island General Laws Chapter 31-23.3 generally prohibits aftermarket sunscreen material on regulated glazing unless an exception applies. The standard passenger-vehicle exception requires at least 70% total VLT measured through the glass and film together.
70% minimum total VLT through passenger-vehicle windshield, side windows, and rear window.
The printed film percentage is not the final reading.
Glass and film are measured together.
| Glass Position | Standard Rhode Island Passenger-Vehicle Rule | Important Detail |
|---|---|---|
| Windshield | At least 70% total VLT | A separate transparent uppermost 6-inch strip exception also exists within direct-view limits |
| Front side windows | At least 70% total VLT | Near-clear film can still lower factory glass below the threshold |
| Rear side windows | At least 70% total VLT | Passenger cars do not receive the multipurpose-vehicle behind-the-driver exception |
| Rear window | At least 70% total VLT | Two outside mirrors must provide a clear rear view when sunscreen material is used |
The Rhode Island DMV warns that stock glass is often already close to 70% VLT. Adding almost any aftermarket film can reduce the combined reading below the minimum on a standard passenger vehicle.
Read official Rhode Island DMV Window Tint Laws ↗Rhode Island · Behind the driver
Rhode Island provides a behind-the-driver exception for listed vehicle classes, including trucks, buses, trailers, mobile homes, campers, multipurpose passenger vehicles, charter buses, funeral-service vehicles, and limousines. The vehicle must have two outside mirrors meeting federal standards and adjusted to provide a clear rear view.
A multipurpose passenger vehicle is defined as a powered vehicle designed to carry ten people or fewer and constructed on a truck chassis or with special features for occasional off-road operation. Marketing language such as 'SUV' does not by itself resolve the statutory classification.
An informational decision aid. This does not determine installation eligibility.
Follow the standard passenger-vehicle rule.
70% total VLTWindshield, side glass, and rear glass, subject to the specific exceptions.
| Glass Position | Eligible Rhode Island Listed Vehicle | Verification Needed |
|---|---|---|
| Windshield | At least 70% total VLT or qualifying uppermost 6-inch strip | Actual meter reading and windshield location |
| Front side windows | At least 70% total VLT | Glass and film combined |
| Windows behind driver | Behind-the-driver sunscreen exception may apply | Registration and statutory vehicle class |
| Mirror requirement | Two compliant outside mirrors with clear rear view | Both mirrors present, compliant, and adjusted |
Important: Do not apply the exception to every crossover, hatchback, or vehicle commonly called an SUV without confirming its legal classification.
Review the official RI vehicle definitions & exceptions ↗Rhode Island · Windshield
Rhode Island's standard exception requires at least 70% total VLT through the windshield. The law separately permits transparent material limited to the uppermost six inches, provided it does not enter the driver's direct forward viewing area.
Because factory windshield glass is often already close to the threshold, a film marketed as 70% can produce a combined reading below 70%. A nominal film percentage is not proof of compliance.
Official RI windshield guidance ↗Rhode Island · Medical exemption
A Rhode Island resident may apply when a Rhode Island-licensed physician or optometrist states that a physical condition makes darker vehicle windows medically necessary. The DMV reviews the application and may issue an exemption sticker for the driver's side window.
Approval is not automatic. Do not assume an exemption is permanent, transferable, or valid for a vehicle that the DMV has not listed.
Rhode Island · Inspection & penalties
Yes. Rhode Island inspections follow the state's official motor-vehicle inspection manual, and a vehicle used for a driving skills test may have only the legal amount of tint described in Rhode Island General Laws Chapter 31-23.3.
A vehicle rejected at inspection is entitled to one free reinspection at the same station within the 30-calendar-day reinspection period. The inspection manual states that this period is not an extension of time to have the vehicle inspected or blanket permission to operate a noncompliant vehicle.
Official RI inspection manual (PDF) ↗Rhode Island General Laws Section 31-23.3-5 authorizes a fine of up to $250 for the owner of a vehicle with noncompliant material.
Official Rhode Island statutory penalties ↗Registration & cross-border driving
Registration status matters, but cross-border operation should not be reduced to a one-line guarantee. Massachusetts Section 9D lists vehicles registered in another state, territory, country, or province as an exception. Rhode Island defines covered motor vehicles as vehicles registered or required to be registered there and separately exempts vehicles not required to be registered there.
Drivers remain responsible for registration, equipment, inspection, and operation. If cross-border use, commercial registration, an unusual vehicle class, or enforcement interpretation matters to the decision, confirm it with the appropriate agency or qualified legal counsel.
Where is the vehicle registered? Our intake asks about the vehicle’s registration, not just where its owner lives. A plate from another state does not guarantee immunity from every jurisdiction’s equipment or operation rules.
Federal & state context
Federal Motor Vehicle Safety Standard No. 205 establishes glazing requirements for new vehicles and motor-vehicle equipment, including a 70% light-transmittance requirement in areas required for driving visibility. State laws separately regulate registered vehicles, owner modifications, inspection, and operation.
These legal layers are not interchangeable. A state VLT allowance does not automatically resolve every federal obligation that may apply to a manufacturer, distributor, dealer, or motor-vehicle repair business.
Official NHTSA interpretation: federal glazing & state operation rules ↗A thoughtful review before film selection
Identify the state where the vehicle is registered or required to be registered.
Review registration and construction rather than relying only on sedan, SUV, truck, or crossover marketing language.
Separate windshield, front doors, windows behind the driver, fixed glass, rear window, and roof glass.
Check factory glass and existing film with a calibrated VLT meter when the threshold matters.
Review the current state-issued waiver or sticker before treating a vehicle as exempt.
Compare the exact XPEL product, nominal VLT, estimated combined result, visibility, and eligible location.
Record product, glass coverage, readings, warnings, waiver status, and customer authorization.

Answers by state, glass & vehicle
Massachusetts generally requires at least 35% total VLT on regulated side and rear glass and limits visible light reflectance to no more than 35%. Windshield material is limited to the uppermost six inches and direct-view limits.
No. The meter reads the glass and film together. Nominal 35% film will normally produce a combined reading below 35% on automotive glass.
Massachusetts Section 9D does not contain Rhode Island's broad listed-vehicle behind-the-driver exception. Review the exact vehicle, registration, glass position, and applicable exception.
Not under the standard rule. Transparent material is limited to the uppermost six inches and cannot enter the driver's direct forward viewing area. The RMV waiver does not authorize tint below the AS-1 line.
An eligible private-passenger owner or insured operator who is medically certified as photophobic or photosensitive may submit the original physician-certified RMV application to Medical Affairs.
Rhode Island generally requires at least 70% total VLT through the windshield, side windows, and rear window of a passenger vehicle.
A 70% film is not automatically compliant. Factory glass is often already close to 70%, so added film can reduce the combined reading below the minimum.
Eligible listed vehicles may use sunscreen material on windows behind the driver when the statutory classification and two-mirror requirements are met.
No. Rhode Island defines the class by seating capacity and construction on a truck chassis or special features for occasional off-road use.
The standard rule requires at least 70% total VLT through the windshield. Because factory glass may be near that level, added film can make the combination noncompliant. A separate uppermost six-inch strip exception exists.
No. The Rhode Island DMV states that medical exemptions do not apply to the windshield.
Yes. Aftermarket tint can be reviewed during inspection, and correction or removal may be required before the vehicle passes.
Massachusetts authorizes a fine up to $250 and license suspension of up to 90 days on a third or later conviction. Rhode Island authorizes a fine up to $250 for the vehicle owner.
No. We can review official sources, inspect and measure the vehicle, document film and coverage, and verify waiver paperwork, but future meters, inspections, enforcement decisions, interpretations, and law changes cannot be guaranteed.
