Ms. Linda Morrow 2908 Eastway Drive Statesville, NC 28677

Dear Ms. Morrow:

This responds to your letter inquiring about the Federal safety standards that would apply to a product you are planning to sell. You stated that the product is a sheet of 1/8 inch tinted acrylic that is held on a side window of a vehicle by four suction cups. The purpose of the sheet is to shield vehicle occupants from the sun. The following discussion explains the applicability of our safety standards to your sun screen.

Pursuant to the National Traffic and Motor Vehicle Safety Act, 15 U.S.C. 1392(a), we have promulgated Federal Motor Vehicle Safety Standard No. 205, 49 CFR 571.205, Glazing Materia1s, which specifies performance and location requirements for glazing used in vehicles. These requirements include specifications for minimum levels of light transmittance (70% in areas requisite for driving visibility, which includes all windows in passenger cars).

No manufacturer or dealer is permitted to install solar films and other sunscreen devices, such as those described in your letter, in new vehicles without certifying that the vehicle continues to be in compliance with the light transmittance requirements of the Standard.

After a vehicle is sold to the consumer, he may alter his vehicle as he pleases, so long as he adheres to all State requirements. Under Federal law, the owner may install the devices regardless of whether the installation adversely affects the light transmittance. Individual States govern the operational use of vehicles by their owners and therefore it is within the authority of the States to preclude owners from applying sun screens on their vehicles.

If a dealer, manufacturer, repair business or distributor installs the sun screen device for the owner of the vehicle, then a violation of S108(a)(2)(A) of the Vehicle Safety Act may result. That section provides that none of those persons may knowingly render inoperative any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable motor vehicle safety standard. Violation of the "render inoperative" provision can result in Federal civil penalties of up to $1,000 for each violation.

If you need further information, the agency will be glad to provide it.

Sincerely,

Frank Berndt Chief Counsel
