Dear Ms. Soodek: This responds to your recent letter asking whether Federal Safet 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*, i 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 Federa 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 fo 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 safet 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 Hug Oates of my office if you have any further questions.; Sincerely, Joseph J. Levin, Jr., Chief Counsel
