SC 20394;
Dear Mr. Davenport: This is to follow up on your phone conversation with Stephen Oesch o my staff concerning the effect of Federal regulations on the tinting of motor vehicle windows. I hope the following discussion answers your questions.; Some background information on how Federal motor vehicle safety law and regulations affect the tinting of vehicle windows may be helpful. Our agency is authorized, under the National Traffic and Motor Vehicle Safety Act, to issue safety standards applicable to new motor vehicles and certain items of motor vehicle equipment. We have 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% in areas requisite for driving visibility, which includes all windows in passenger cars).; You first asked if the Federal motor vehicle safety standards apply t foreign vehicles sold in the United States. As with all our standards, Standard No. 205 applies to any new vehicle, whether made by a foreign or domestic company, manufactured for sale in the United States. Thus, no manufacturer or dealer is permitted to install solar films and other sun screen devices, such as the one described in your letter, in *new* vehicles without certifying that the vehicle continues to be in compliance with the light transmittance and other requirements of the standard. Violation of Standard No. 205 can result in Federal civil penalties of up to $1,000 for each violation. In addition, a manufacturer of a vehicle that does not comply with our standards is required to remedy any noncompliances in its vehicles.; You also asked how Federal law affects businesses that tinted th windows of used vehicles. After a vehicle is first sold to a consumer, modifications to a vehicle are affected by section 108(a)(2)(A) of the Vehicle Safety Act. That section prohibits commercial businesses from tampering with safety equipment installed on a vehicle in compliance with our standards. Thus, no dealer, manufacturer, repair business or distributor can install a sun screen device for the owner of the vehicle, if the device would cause the window not to meet the requirements of Standard No. 205. Violation of the section 108(a)(2)(A) can result in Federal civil penalties of up to $1,000 for each violation.; Section 108(a)(2)(A) does not affect vehicle owners, who may themselve alter their vehicles as they please, so long as they adhere to all State requirements. Under Federal law, the owner may install sun screening 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 using sun screens in their vehicles.; If you need further information, please let me know. Sincerely, Erika Z. Jones, Chief Counsel
