TITLE: FMVSS INTERPRETATION

TEXT: This responds to your recent letter asking whether Federal Safety Standard No. 205 specifies requirements limiting the reflectivity of glazing materials. You are concerned with the lack of uniformity in state laws that prohibit nontransparent or reflective windows in motor vehicles.

The stated purpose of Safety Standard No. 205, Glazing Materials, is to reduce injuries resulting from impact to glazing surfaces, to ensure a necessary degree of transparency in motor vehicle windows for driver visibility, and to minimize the possibility of occupants being thrown through the vehicle windows in collisions. The standard does not prohibit reflective glazing, nor does it specify requirements that would limit the degree of reflectivity of glazing materials.

Since reflectivity is not an aspect of performance governed by Federal safety standards, state laws concerning glazing reflectance would not be preempted by Standard No. 205. Safety Standard No. 205 does, however, specify requirements for the luminous transmittance of glazing materials for use in motor vehicles. Therefore, state laws prohibiting nontransparent windows would be preempted if they attempted to regulate the glazing manufacturer or the vehicle manufacturer (15 U.S.C. 1392(d)). State regulations applicable to the vehicle owner or user would not be preempted, on the other hand, since the Federal regulation is only applicable to the manufacturer. Therefore, a state law could prohibit the application of a nontransparent decal on a window by a vehicle owner, for example.

I am enclosing a copy of the California Highway Patrol petition for rulemaking regarding glazing abrasion requirements and glazing reflectivity. A notice concerning this petition will be issued at some time in the near future.

I must point out that our statutory authority requires all safety standards to be reasonable, objective and to meet the need for motor vehicle safety. The agency cannot, therefore, regulate an aspect of motor vehicle performance or design if there is no data or evidence indicating that a safety problem exists.

I hope this has been responsive to your inquiry. Please contact Hugh Oates of my office if you have any further questions.

SINCERELY,

AUTOMOTIVE PARTS & ACCESSORIES ASSOCIATION

Joseph Levin Chief Counsel National Highway Traffic Safety Administration Dear Mr. Levin:

This letter is to request a formal interpretation of FMVSS #205, Glazing Materials, as to the permissibility of reflective material. In addition, we have posed specific questions under #205 regarding federal jurisdiction and applicability of the Standard. Our desire is to prevent the possible emergence of fifty varying state laws governing reflectance.

May we provide an explanation of our interest, and previous communication with the NHTSA on the subject.

APAA is a national trade association representing nearly 1400 manufacturers, retailers, wholesale distributors, and independent sales agents doing business in the volume aftermarket industry. Among our members are manufacturers of a variety of window covering materials, including screens, reflective materials, and tinted materials.

As a service to these manufacturers and our retailers, we attempt to keep abreast of state laws bearing upon the sale and use of various window covering materials. The following states have enacted regulations prohibiting nontransparent or reflective windows: Colorado, Florida, Kansas, Nebraska, Ohio, Utah, and Virginia. The states of California and Pennsylvania are considering the same. Lesser restrictions exist in Maryland, New Mexico, and Texas. With only two exceptions, the terms "nontransparent" and "reflective" are undefined and enforcement is left to the judgement of police, the Highway Patrol, or an inspection official. (See enclosed APAA prepared summary bulletin). This lack of definition has resulted in violations for windows which actually complied with federal visibility requirements as defined by ANSI Z26.

Yet, some of the states have demanded recall of reflective windows, the related costs and logistical problems of which severely disrupt interstate commerce and can drive a small manufacturer out of business. Uniformity, through federal preemption, would allow our manufacturers to comply in "good faith" with reflectance requirements.

On March 13, Mr. Guy Hunter (engineer) and Mr. Hugh Oates (legal adviser) to FMVSS # 205 met with Mr. Russ Simmons of West Custom Windows, an APAA-member company, Mr. Julian C. Morris, APAA President, and myself to discuss the association's request for an amendment to the standard to address reflectance levels.

We were advised the NHTSA may be considering the reflectance issue in response to a petition filed last year by the California Highway Patrol. May we be furnished with a copy of the CHP's petition and be apprised of rulemaking status?

Presumably, the Administration has not previously addressed reflectivity in FMVSS #205 because reflective windows have not created an established safety hazard. However, could not an amendment be made on the basis of benefits in safety from filtering out glare or benefits in fuel economy from the insulation properties of reflective material? What type of data is acceptable to demonstrate that establishing an acceptable percentage reflectance level would result in safety and fuel economy benefits?

A legal opinion from your office would provide clarification that the federal standard does not prohibit reflective material. The crux of the problem, it would appear, lies in applicability of FMVSS #205. At the March 13 meeting at NHTSA headquarters, staff advised us that the standard applies to the vehicle manufacturer, not the motorist. Are the states then on sound legal ground to regulate the vehicle owner, even a state's interpretation of "nontransparency" is stricter than the visibility definition incorporated by #205?

Your response to these questions will, hopefully, provide reasonable guidelines for dealing with the existing ambiguities.
