Dear Mr. Kallman: This responds to your letter of January 14, 1985, concerning wha regulations affect a process you intend to market for new and used cars. The process consists of grinding two parallel grooves into the lower portion of the windshield. The grooves are 2mm wide, 0.1-0.3mm deep, and are 2mm from each other. You stated that the purpose of the grooves is to improve the efficiency of the wipers and increase their life expectancy. The following discussions address the effect of our regulations on the process you described.; First, let me explain how our regulations apply to a new vehicle or t a new windshield sold as an item of replacement equipment. Our agency has issued Standard No. 205, *Glazing Materials*, which sets performance requirements for glazing materials used in new vehicles or sold as items of replacement equipment. I have enclosed a copy of the standard. If, before they are sold, the safety grooves are ground into either the windshield of a new vehicle or into a new windshield sold as an item of replacement of equipment, the person making the grooves would have to certify that the glazing continues to be in compliance with all of the requirements of Standard No. 205 for windshields. I note that the test results enclosed with your letter do not address whether the glazing would continue to comply with the requirements after it has had the safety grooves ground into it. In particular, we would urge you to determine whether the glazing would continue to comply with the requirements regarding impact and penetration resistance, optical deviation and visual distortion after the grooves have been ground into the windshield. Purchasers of a new vehicle may alter the vehicle as they please, so long as they adhere to all State requirements.; If the safety grooves are ground into the windshield of a used vehicle then Section 108 (a)(2)(A) of the National Traffic and Motor Safety Act may apply. That section provides that no manufacturer, distributor, dealer or motor vehicle repair business shall knowingly render inoperative any device or element of design installed on or in a motor vehicle in compliance with an applicable motor vehicle safety standard. Thus, none of those persons may knowingly grind the grooves into a vehicle's windshield if by so doing they would render inoperative the compliance of the vehicle's glazing with Standard No. 205. Violation of this section can result in Federal civil penalties up to $1,000 for each violation.; If you have any further questions, please let me know. Sincerely, Frank Berndt, Chief Counsel
