Dear Mr. Kallman:

This responds to your letter asking for further clarification of a March 1, 1985 letter to you from the Chief Counsel of this agency. Your company is marketing a process in which parallel grooves are ground into the lower portion of the windshield of vehicles. In our March 1, 1985 letter to you, we set forth a general description of the requirements that would apply if the process were used on new vehicles or new windshields sold as an item of replacement equipment, and those requirements that would apply if the process were used on vehicles that had already been sold to the first purchaser or windshields that were already installed in vehicles. Your letter explains that your company now uses this process only on vehicles that have already been sold to a first purchaser and windshields already installed in vehicles. You asked for clarification of several issues in your letter.

1. Your company has obtained test reports from two laboratories on the process of grinding these parallel grooves into the lower portions of windshields. One of these reports specifically states that windshields with these grooves fully comply with all requirements of Standard No. 205, Glazing Materials (49 CFR /571.205). You asked whether the steps your company has taken are "sufficient to show compliance with Standard No. 205."

Response: The National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq.) does not permit this agency to assure any person or entity that its products or processes comply with all applicable requirements or to "approve" some product or process. Instead, section 114 of the Safety Act (15 U.S.C. 1403) requires the manufacturer itself to certify that its products comply with all applicable safety standards.

Standard No. 205 requires that the windshields installed in new vehicles and new windshields sold as replacement equipment to meet certain performance requirements, and requires the windshield to be certified as complying with those requirements. You have stated that your company's process of grinding grooves into windshields will not be used on new vehicles or new windshields. Standard No. 205 does not require that windshields be certified as continuing to comply after being treated by aftermarket processes, such as your company's grooving process. Accordingly, if your grooving process is used only in aftermarket applications, your company is not required to certify that those windshields continue to comply with Standard No. 205 after grooves have been ground into the windshield. However, continued compliance with Standard 205 is important, for a different reason, discussed below.

Even though Standard No. 205 does not directly apply to your process, and your company does not have to certify continued compliance with Standard No. 205, section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)) does impose an obligation on manufacturers, distributors, dealers, and repair businesses, including your licensees, with respect to aftermarket processes. That section provides: "No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle ... in compliance with an applicable Federal motor vehicle safety standard ..."

In this case, a number of elements of design have been installed in the windshield of motor vehicles in compliance with Standard No. 205, including impact and penetration resistance, optical deviation limitations and limitations on visual distortion. If grinding grooves into the windshield by means of your company's process would cause the windshield to no longer comply with these or some other requirements of Standard No. 205, grinding the grooves into the windshield would be a violation of the "render inoperative" provision of the Safety Act.

The Safety Act imposes a responsibility on manufacturers, distributors, dealers, and repair businesses to ensure, in the first instance, that none of the aftermarket operations they perform will result in a violation of the "render inoperative" provision. NHTSA reexamines the initial determinations made by any of these parties only in the context of an enforcement proceeding. If your company has concluded that the test reports enclosed with your letter show no "rendering inoperative" when grooves are ground into windshields, NHTSA will not express any view on that conclusion unless and until the agency begins some enforcement proceeding to examine this grooving process.

In keeping with this statutory scheme, neither our March 1, 1985 letter nor this letter expressed any agency opinion as to whether dealers using your company's process to grind grooves into windshields of vehicles would or would not render inoperative the windshield's compliance with Standard No. 205. Instead, both these letters are intended only to alert your company to the elements of design that might be rendered inoperative by grinding grooves in windshields by your process.

2. Would it be possible for your company to indicate on the windshields in which you grind these grooves that your company has "shown compliance with Standard No. 205," for example, by affixing a clear sticker to that effect?

Response: As explained above, only new windshields or windshields installed in new vehicles must be certified as complying with Standard No. 205. There is no requirement that windshields subjected to aftermarket processes be certified as still complying with the standard. If your company voluntarily chooses to provide some indication of continuing compliance, it is free to do so. NHTSA has long said that the only restriction on voluntary markings is that those markings must not obscure or confuse the meaning of any required markings on the product. Assuming that your voluntary markings will not obscure or confuse the meaning of the required markings on the windshield, the voluntary marking would not violate any Federal requirements. You should be aware, however, that some State laws restrict stickers and other items placed on automobile windshields.

3. Is your company required to show continuing compliance with Standard No. 212, Windshield Mounting (49 CFR /571.212) for vehicles whose windshields have grooves ground in accordance with your company's process?

Response: The vehicle manufacturer is responsible for certifying that each of its new vehicles complies with the requirements of Standard No. 212. There is no obligation for any person that performs aftermarket operations on the vehicle or its windshield to certify continuing compliance with Standard No. 212.

As explained above, the only requirement applicable to aftermarket operations on a vehicle is that manufacturers, distributors, dealers and repair businesses are prohibited from "rendering inoperative" a vehicle's compliance with any safety standard, including Standard No. 212. Standard No. 212 requires a vehicle to retain a specified percentage of the windshield periphery. To avoid violating the "render inoperative" prohibition, I suggest that you carefully examine the process by which grooves are ground into windshields and determine whether the installation of those grooves in accordance with your company's process would result in the vehicle no longer complying with Standard No. 212. Your company is obliged to determine that this grooving process will not result in a rendering inoperative violation with respect to Standard No. 212. As explained above, NHTSA will not express any views about your company's determination except in the context of an enforcement proceeding.

I hope this information is helpful. Please let me know if you have any further questions on this subject.

Sincerely,

Erika Z. Jones Chief Counsel
