Suggested Model Legislation for Automotive Window Tinting

Model legislation that is applicable to each and every jurisdiction is not possible because most jurisdictions amend existing safety or glazing statutes to restrict window film. Generally, the law that sets the standard for window film also specifies the restriction for signs, decals, and stickers.

New Law for Big Rig Truckers (Press Release)

The summary chart of state aftermarket tint law information is not a legal document.It is the result of independent research, using several sources of public state documents. Window tinting laws vary from state to state and province to province. Before applying any window tinting materials, installers should thoroughly review the appropriate state regulations as well as local enforcement policies to insure compliance with all applicable standards.

FilmVLT%: Refers to the film itself 

Net VLT%:  Refers to the combined film & glass

Vague: The language of the law is unclear, legislative intent is unclear, or interpretation is uncertain.

Windshield: Presumably, NR tinting is permitted above the AS-1 line. If the law specifies only the AS-1 line, AS-1 appears. If AS-1 or specified inches appears, the AS-1 is assumed and only the number of inches down appears.(Note: NR is used in lieu of “No, Any, or a specific percentage” when the law permits unspecified “nonobstructive” or “Transparent” tinting materials. In these cases, the legality of tinting inevitably depends upon each officer’s discretion.

Front Sides: No film, or the actual percentage of VLT permitted. (Note: Because they may vary from state to state, manufacturer’s tolerances (i.e. + / - 3% VLT) are not listed on this chart, not are they included in these VLT numbers.)

MPV: Multi Purpose Vehicle, a vehicle with motive power, except a trailer, designed to carry ten people or less that is constructed either on a truck chassis or has special features for occasional off-road operation.

Back Sides: No film, or the actual percentage of VLT permitted.

Rear: No film, or the actual percentage of VLT permitted.

% of Reflectivity: NR No metallic or mirrored appearance

NE: Not excessive (not specific)

MNIR: Must not increase reflectivity

MBNR: Must be non-reflective (not specific)

NMMA: No metallic or mirror

Texas Senate Bill 589 - April 19, 2010

Senate Bill 589 (House Bill 4523)

The Legislative Alert dated December 11, 2009, provided updated information to members relative to the implementation of Senate Bill 589 which became effective on September 1, 2009. It was noted that the actual language of the legislation did not seem to represent the original intent of the legislative leadership, and it was suggested that members carefully consider retaining the 25 percent standard to avoid installing products that may have been considered illegal in the future.
