The Honorable Robert A. Young Member of Congress 4150 Cypress Road St. Ann, MO 63074

Dear Mr. Young:

Thank you for your letter of October 13, 1983, concerning the potential hazards posed to law enforcement officials by the use of opaque glass in automobiles. Through the exercise of its motor vehicle safety authority, the agency has addressed a part of this potential problem. However, given the limitations on the agency's authority, additional State action is needed to eliminate this potential problem.

Pursuant to the National Traffic and Motor Vehicle Safety Act, the agency has issued Federal Motor Vehicle Safety Standard No. 205, Glazing Materials, which specifies performance and location requirements for glazing used in vehicles. These requirements include specifications for minimum levels of light transmittance (70 percent in areas requisite for driving visibility, which includes all windows in passenger cars) and abrasion resistance. The specification for light transmittance precludes darkly-tinted windows in new automobiles.

In past interpretation letters, the agency has said that solar film and other materials used to make windows opaque are not glazing materials themselves and would not have to comply with Standard No. 205. However, installation of such films on new motor vehicles would be prohibited if the vehicle glazing no longer complied with the light transmittance or abrasion resistance requirements of the standard. If a manufacturer or a dealer places the film on glazing in a vehicle prior to the first sale of the vehicle, that manufacturer or dealer has to certify that the glazing continues to be in compliance with the requirements of Standard No. 205.

After a new vehicle has been sold to the consumer, he may alter the vehicle as he pleases, so long as he adheres to all State requirements. Under Federal law, the owner could install the tinting or other film on glazing in his vehicle whether or not the installation adversely affected the light transmittance and abrasion resistance of the glazing. Section 108(a)(2)(A) of the Vehicle Safety Act provides that no manufacturer, distributor, dealer or motor vehicle repair business shall knowingly render inoperative any device or element of design installed on or in a motor vehicle in compliance with an applicable motor vehicle safety standard. "Render inoperative" means to remove, disconnect or degrade the performance of a system or element of design installed to comply with a Federal safety standard. Thus, none of those persons may knowingly install a tinting or other film on a vehicle for an owner if that action would render inoperative the light transmittance or abrasion resistance perfomance of the vehicle's glazing. Violation of the render inoperative provision can result in Federal civil penalties of up to ,000 for each violation.

State law, rather than Federal law, governs the operational use of vehicles by their owners. Thus, it is up to the States to preclude owners from applying tinting or other films to their vehicle windows. A number of States have already adopted such laws. The agency would be glad to provide technical assistance on glazing requirements to the appropriate Missouri highway safety officials working on this problem.

I hope this explains the agency's authority to address the potential problems posed by tinting and other films. If you need further information, the agency will be glad to provide it.

Sincerely,

Diane K. Steed

Dear Ms. Steed,

Enclosed is a letter from Mr. James Stewart, Director of the National Institute of Justice, in regard to potential safety hazards posed to law enforcement officials by the presence of opaque glass in automobiles. As you will note, Mr. Stewart feels your Agency might be of some assistance in this matter.

I would appreciate your review of the potential dangers of this situation. Please advise me of your findings by writing my district office in St. Ann, Missouri.

With best regards,

Sincerely,

Robert A. Young Member of Congress

Enclosure

The Honorable Robert A. Young House of Representatives Washington, D.C. 20515

Dear Congressman Young:

This is in response to your letter on behalf of Overland Police Chief Eddy Williams concerning the problem of opaque glass in automobiles.

As a former chief of the detective division of the Oakland, California, Police Department, I can appreciate Chief Williams' concern about this possible hazard to law enforcement officers. At present, the National Institute of Justice has no information on this problem. However, I have asked my staff to look into the matter and will keep you apprised of our findings.

Meanwhile, I would suggest that Chief Williams contact the Department of Transportation's National Highway Traffic Safety Administration, Washington, D.C. 20590, regarding this growing danger. The NHTSA conducts programs relating to the safety of motor vehicles and provides Federal matching funds to assist States with their motor vehicle safety programs. Perhaps the NHTSA could help in alerting States and automobile manufacturers to the danger opaque glass in autos presents to police officers who must stop and approach such vehicles without being able to see the persons inside.

Thank you for your interest in the well being of the Nation's public safety officers. If I can be of further assistance, please do not hesitate to contact me.

Sincerely,

James R. Stewart Director National Institute of Justice
