Senate Bill 589

To: Texas Manufacturers, Distributors, and Installers

From: Lynwood Butner, Legislative Consultant

Date: April 19, 2010

Subject: 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.

There have been no legislative initiatives to amend the adopted language during the 2010 Legislature; and the adopted language, Senate Bill 589, which is now the law, has been published as the regulatory standard on the Department of Public Safety Inspection website (http://www.txdps.state.tx.us/vi/Misc/faq/tint.htm).

The specific language contained in the regulation for rear side and a rear window is as follows: Side Windows to the Rear of the Driver
(Revised September 1, 2009)
These windows are completely exempted from regulation under the Texas Transportation Code. Reference Legislation: Senate Bill 589.

Rear Window
A sunscreening device can be applied to the rear window of the vehicle if the following conditions are met.If a motor vehicle is equipped with an outside mirror on each side of the vehicle that reflects to the vehicle operator a view of the roadway for a distance of at least 200 feet from the rear of the vehicle then there are no restrictions regarding the sunscreening devices applied to the rear window.

If a motor vehicle is not equipped with such mirrors then the rear window must meet the following standards: Sunscreening devices, when measured in combination with the original glass, must have a light transmittance value of 25% or more. Sunscreening devices, when measured in combination with the original glass, must have a luminous reflectance value of 25% or less.

All members should fully comply with the adopted standards unless changes are made during the current legislative session at which time members will be advised.
