Find your state’s tint rules.

Measured through the tinted window. The statute provides a measurement tolerance of at least 3%; do not use it as a lower installation target.

The ordinary rule measures the entire window, including glazing. Do not assume an SUV qualifies for an exception without checking its manufacturer classification.

The statute specifies 33% light transmission, plus or minus 3 percentage points, for film and glazing together. Do not treat the tolerance as the installation target.

The ordinary numerical provisions cover model year 1994 onward; older vehicles have transitional rules.

The official text retrieved requires clear, colorless, transparent UV-blocking material with at least 88% VLT, plus at least 70% VLT through the glass and material together. Other safety-standard and certificate requirements also apply. This is not permission to install ordinary 70%-rated tint film.

The 27% rule addresses Colorado-registered vehicles. Rear windows below 27% require front sides and windshield at least 70% under the stated exception.

Use the finished glass-and-film reading. The statutory three-point allowance is not a recommendation to install darker film.

The amended statute describes the tint or other material’s VLT. The older posted regulation instead measures glass plus film at 70%; no updated official inspection interpretation was found.

Confirm that the vehicle actually falls within the statutory mini-van category before using its different limit.

For ordinary non-exempt installations, the front side windows must transmit at least 28% of visible light when the material is applied to and tested on the specific vehicle's glass. Front-side reflectance cannot exceed 25%.

Section 3 of 2026 Act 640; statutory ±3% tolerance is not an installation target.

The law specifies at least 35% light transmittance, plus or minus 6 percentage points, through film and glazing together. Select film to meet the standard rather than aiming at the variance.

Section 49-944 specifies 35%, with a 3-percentage-point tolerance. Ask the installer to check the finished window as well as the film specification.

The complete current statute could not be verified. Rear treatment and factory glazing affect the options; see the guide’s source limitations.

Section 9-19-19-4(c) joins reflectance above 25% and transmission below 30% with “and.” Agency guidance recommends at least 30% transmission and at most 25% reflectance; do not treat the wording as permission for darker film.

Effective July 1, 2026; windshield remains 70%.

Total transmission includes the glazing and installed screening material.

KRS 189.110 specifies testing the film on 1/8-inch clear glass; do not describe this simply as 35% through every installed window.

Glass and film together; all tolerances are already included in the stated minimum.

The statute expressly measures transmission through both the glass and the added material.

Heavy trucks, buses, limousines and specified larger multipurpose vehicles have stricter rules; check class and weight.

The official inspection guideline expressly measures glass plus film and rejects a reading below 35%; a film labeled 35% may read lower once installed.

Ordinarily the top four inches; full front-side film needs an applicable exception.

Ordinary nonexempt windows; the statutory ±3% tolerance is not a recommended tint target.

The inspected window must meet the requirement; a film’s package percentage is not the finished-window reading.

Glass and screening together; ±3% statutory tolerance is not a recommended installation target.

For vehicles required to be registered in Montana, front side windows must transmit at least 24% and reflect no more than 35%, unless a valid exception applies.

Rear-window vehicle-class exceptions do not relax the front-side limit.

The statute explicitly measures the combined transparent material and safety glazing and supplies a 7-percentage-point tolerance. Use 35% as the planning standard.

This is the tinted-window reading; film labeled 70% may yield a lower reading when applied to factory glass.

Retailers must see the required medical certificate before applying front tint to a New Jersey-registered vehicle. No ordinary numerical front VLT limit or guaranteed traffic-stop outcome is established.

The current statute calls for nonreflective sun screening material with at least 20% light transmission and both outside mirrors. It does not expressly resolve the enforcement testing basis for film versus the finished window.

Seventy percent must pass through the finished window; a film’s standalone rating is not the installed reading.

The statute presumes compliance for an approved-meter reading above 32%; that testing rule is not a 32% film recommendation.

Effective August 1, 2025; includes factory glass and added film.

Combined glass and film; the rule includes ±3% tolerance, not a darker installation target.

The statute includes glazing, coating and sunscreening material in its definition of a window.

Both transmission tests matter, along with the film’s maximum 13% reflectance. A product called 35% film does not satisfy the ordinary 50% film rule.

Use the vehicle’s model year and legal class. The table’s ±3% accuracy statement is not an installation target.

Rhode Island DMV expressly describes total transmission through the installed window, not the tint film alone.

For ordinary front-side aftermarket tint, the added device and factory material together must meet the limit.

The statute separately states a 9% enforcement tolerance; target the stated minimum.

Confirm the regulated pane and finished installation; do not rely on the percentage printed on film packaging.

For ordinary non-commercial aftermarket front side tint. The statute's limited measurement variance is not a darker installation target.

A peace officer’s metering observation has a maximum 5-percentage-point variance. This is separate from the 35% standard used when choosing an installation.

A medical exemption requires DMV approval and applies only to the authorized front-side/vent windows.

Total transmission includes glass and film. The minus-seven-point law-enforcement measurement tolerance is not an installation target.

Net film screening includes manufacturer-applied material and aftermarket film. Only one sheet of aftermarket sunscreening film may be installed on a window.

The front-side rule applies to the sunscreen device used with automotive safety glazing; check the completed window.

Measured through glass and film together; the 3% testing tolerance is not a darker tint target.

Section 31-5-962 expressly measures total light through both sunscreening material and glazing. A 28%-rated film alone does not establish compliance.
