Dear Ms. Tsujishita: Thank you for your letter requesting an interpretation of th requirements of three of our safety standards. This letter responds to your questions concerning Standard No. 201, *Occupant Protection in Interior Impact*. I have previously responded to your requests for interpretations of the other two standards. I regret the delay in this response.; Your questions concern the requirements of S3.5.1(b) of the standard which provides that 'Along not less than 2 continuous inches of its length, the armrest shall, when measured vertically in side elevation, provide at least 2 inches of coverage within the pelvic impact area.' You expressed concern about determining whether several different armrest designs comply with that requirement. Specifically, you provided three examples and asked how the requirement would apply to each example. Your example I11.1 is an armrest that, when viewed in side elevation (i.e., a view in which a person is looking from in front or behind an armrest to determine how the armrest projects from the door surface) has a flat surface. Example I11.2 is an armrest that has a slightly curved surface. Example I11.3 is an armrest with a surface that is steeply angled inward toward the door. Because of the angling of the armrest, it has a sharp projection at its top.; You believe that examples I11.1 and I11.2 comply with the requiremen of S3.5.1(c). You also believe that example I11.3 would not comply because of its sharp projection. However, you expressed concern about what criteria should be used to distinguish example I11.2 from example I11.3.; S3.5.1(c) of Standard No. 201 does not set any radius of curvatur requirements for armrest surfaces. Thus, a manufacturer is not required to provide an armrest with a flat surface. The only requirement is that the armrest provides at least two inches of coverage within the pelvic impact area. The purpose of the requirement is to reduce potential injuries to an occupant by ensuring that the armrest has a minimum surface area that will spread the force resulting from an occupant impacting the armrest in a crash. Thus, for this requirement to have a meaningful effect, an armrest should be designed to ensure that there is at least two inches of contact between the surface of the armrest and the pelvic impact area of an occupant. If your examples I11.1 and I11.2 provide two inches of coverage within the pelvic impact area, they would appear to comply, since they present an essentially flat surface. Based on your drawing, it appears that the steep inwardly sloping angle of the armrest shown in example I11.3 may not contact a minimum of two inches of the pelvic impact area. One method of determining the degree of occupant contact would be to measure the amount of contact between a test dummy and the armrest in a static push test or in a dynamic side impact test. We share your concern that an armrest not have sharp projections which could concentrate potentially harmful forces on an occupant striking the armrest.; Finally, you provide a drawing of an additional armrest. Briefl described, the armrest has a slightly curved surface with a decreasing radius within the pelvic impact area. At the top of the portion of the armrest within the pelvic impact area there is a small indentation. The agency has previously said, in an interpretation letter of July 1, 1893 to MMC Services, Inc., that bezels and other indentations are not precluded by the standard. However, the area of the indentation will not be measured in determining whether the armrest provides two inches of coverage if the indentation is so deep that it cannot be contacted. Based on your drawing, the indentations shown in your proposed armrest is shallow and would be contactable by an occupant. Thus, the surface area of the indentation would be counted in determining whether the vehicle complied.; Finally, I would point out that S3.5.1(c) is one of three optiona means of compliance that manufacturers may choose. A manufacturer may also meet the requirements of Standard No. 201 by complying with either S3.5.1(a) or S3.5.1(b), in which case it is not necessary to provide two inches of coverage with the pelvic impact area.; If you have any further questions, please let me know. Sincerely, Erika Z. Jones, Chief Counsel

"Dear Mr. Snyder: This is in response to your letter of May 11, 1995 asking whether a client of yours is a 'final stage manufacturer' within the meaning of the National Traffic and Motor Vehicle Safety Act and implementing regulations on manufacturer identification and vehicle certification found in 49 CFR Parts 566, 567, and 568. You have described this client as being engaged in the manufacture of completed heavy duty dump trucks, vans, and road tractors from used chassis-cabs. The term 'manufacturer' is defined in 49 U.S.C. 30102(a)(5) (formerly section 102(5) of the National Traffic and Motor Vehicle Safety Act) as 'a person- (A) manufacturing or assembling motor vehicles or motor vehicle equipment . . . ' (emphasis added). Based on your description of your client as being engaged in the assembly of completed motor vehicles, it would appear to meet this definition. Because the manufacturer identification requirements of 49 CFR Part 566 apply to 'all manufacturers of motor vehicles,' as stated in section 566.3 of that Part, your client would be required to submit to the National Highway Traffic Safety Administration (NHTSA) the identifying information specified in 49 CFR 566.5. The term 'final stage manufacturer' is defined at 49 CFR 568.3 as 'a person who performs such manufacturing operations on an incomplete vehicle that it becomes a completed vehicle.' An 'incomplete vehicle' is defined in that section as 'an assemblage consisting, at a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system . . . that requires further manufacturing operations . . . to become a completed vehicle.' The term 'completed vehicle' is in turn defined in section 568.3 as 'a vehicle that requires no further manufacturing operations to perform its intended function . . . .' Based on your description of your client as being engaged in the manufacture of completed heavy duty dump trucks, vans, and road tractors from chassis-cabs, it would qualify as a final stage manufacturer, as that term is defined in section 568.3. Requirements for final stage manufacturers are specified at 49 CFR 568.6. This section provides that a final stage manufacturer shall complete each vehicle 'in such a manner that it conforms to the Federal motor vehicle safety standards in effect on the date of manufacture of the incomplete vehicle, the date of final completion, or a date between those two dates,' and shall affix a label to the vehicle attesting to that conformance in accordance with 49 CFR 567.5, which specifies certification requirements for vehicles manufactured in two or more stages. These certification requirements are in implementation of 49 U.S.C. 30115, which requires the manufacturer of a new motor vehicle to certify to the dealer or distributor at delivery that the vehicle complies with applicable motor vehicle safety standards. NHTSA has long taken the position, however, that a vehicle is used if it is assembled by adding a new body to the chassis of a vehicle previously registered for use on the public roads. As a consequence, your client would not be required to certify the vehicles that it manufactures in this fashion. Your client would nevertheless be subject to 49 U.S.C. 30122(b), which provides that ' a manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle . . . in compliance with an applicable motor vehicle safety standard . . . .' NHTSA has interpreted this provision as requiring any of the specified entities that remove an old body from a vehicle in order to install a new one to ensure that the newly completed vehicle meets the standards that the vehicle was originally required to meet. For example, a vehicle consisting of a body manufactured in 1995 mounted on a used 1989 chassis must meet all standards that applied to 1989 vehicles. Your client would be liable for any violation of this requirement on vehicles that it manufactures, regardless of whether it removed the body from the old vehicle itself, or directed another entity to do so. Additionally, as a vehicle manufacturer, your client would be required under 49 U.S.C. 30118 to furnish owners with notification of, and a remedy for, any safety-related defect or any noncompliance with an applicable Federal motor vehicle safety standard that is found to exist in a vehicle that it assembles. If you have any further questions regarding this matter, feel free to contact Coleman Sachs of my staff at the above address, or by telephone at (202) 366- 5238. Sincerely, John Womack Acting Chief Counsel";

"Dear Mr. Jackson: This is in response to your letter which requeste our interpretation of the applicability of certification requirements to your company. You indicate that you attached a new body to a truck chassis that has been in service for a number of years. Your customer believes that Trailmaster Tanks, Inc., (Trailmaster) should have issued a new final-stage manufacturer certificate at the time of the mounting of the new body. Trailmaster, on the other hand, is of the opinion that the final-stage manufacturer certificate is only issued when the chassis is new. You asked me whether your company was required by Federal law or regulations to certify that the new body on the used truck chassis complies with all applicable safety standards. The answer to your question depends on whether the used chassis consisted of any new components and, if not, whether the used components of the chassis came from different vehicles, as explained below. As a general matter, our safety standards and certification requirements apply to vehicles only before the first sale of the vehicle in good faith for purposes other than resale. Generally speaking, vehicles that are produced from a chassis that has already been sold to the public are not considered new vehicles, and are not subject to our safety standards or certification requirements. However, there is a special provision in our regulations for vehicles that are produced by combining new and used components. This provision is in 49 CFR 571.7(e), which provides: (e) Combining new and used components. When a new cab is used in the assembly of a truck, the truck will be considered newly manufactured for purposes of paragraph (a) of this section, the application of the requirements of this chapter, and the Act, unless the engine, transmission, and drive axle(s) (as a minimum) of the assembled vehicle are not new, and at least two of these components are from the same vehicle. This regulation means that a party attaching a new body to an old chassis is not required to attach a new certification label or make any certification under Federal law if that party simply uses the engine, transmission, and drive axle that are installed on the old chassis at the time the party receives the old chassis. Based on your statement that the truck 'was not modified in any way' at the time the new body was installed on the old chassis, this would appear to be the case in your situation. If this is true, you were not required to make any certification in connection with this vehicle. On the other hand, if you substituted a new engine, transmission, or drive axle in the old chassis when you attached the new body, the vehicle was considered newly manufactured under 571.7(e) and your company was required to certify the vehicle in accordance with Part 567. Similarly, if you substituted used components on the old chassis at the time you attached the new body, the vehicle was considered newly manufactured unless at least two of the three specified components (engine, transmission, and drive axle) were from the same vehicle. It should be noted that, even if the vehicle created when you attached a new body to a used truck chassis did not result in a newly manufactured vehicle pursuant to 49 CFR 571.7(e), your company was still subject to the provisions of section 108(a)(2)(A) of the Safety Act. This section prohibits any manufacturer, distributor, dealer or motor vehicle repair business from 'knowingly rendering inoperative' any equipment or element of design installed on a vehicle in compliance with our safety standards. In other words, no manufacturer, dealer, distributor, or repair business can modify used vehicles by removing or defeating any of the systems or devices that were installed on the vehicle to comply with an applicable safety standard. The modifier in the first instance must determine if the modifications constitute a prohibited 'rendering inoperative' violation. However, the agency can reexamine the modifier's determination in the context of an enforcement proceeding. I believe you can use the information presented in this letter to determine whether or not the vehicle your company made was considered a newly manufactured vehicle, subject to our safety standards and certification regulations. If you have any further questions or need additional information, please feel free to contact us. Sincerely, Erika Z. Jones Chief Counsel";

Dear Ms. Hartman: Thank you for your letter of February 27, 1986, asking how ou regulations affect a product you are considering. In your letter, you asked the agency not to disclose your idea for this product. In a phone conversation of April 28, 1986, with Stephen Oesch of my staff, you waived your request for complete nondisclosure and agreed to the disclosure of a generic description of your product. As you requested, we will not disclose the specific details of your product or the sketches you enclosed with your letter.; Your product is designed to reduce the possibility that a young chil could unbuckle a vehicle safety belt. The product would enclose the buckle of the safety belt, so that it is difficult for a child to operate the buckle release.; We have significant reservations about your product. I hope th following discussion explains our reservations and the effect of our regulations on your product.; Our agency has the authority to issue safety standards applicable t new motor vehicles and certain items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. Instead the National Traffic and Motor Vehicle Safety Act establishes a 'self-certification' process under which each manufacturer is responsible for certifying that its products meet our safety standards. The agency periodically tests vehicles and equipment items for compliance with the standards, and also investigates other alleged safety-related defects.; Although we do not have any standards that directly apply to you product, we do have several statutory provisions that could affect it. Manufacturers of motor vehicle equipment such as your product are subject to the requirements in sections 151-159 of the Vehicle Safety Act concerning the recall and remedy of products with defects related to motor vehicle safety. The agency does not determine the existence of safety defects except in the context of a defect proceeding, and thus is unable to say whether your product might or might not contain such a defect. However, the agency has reservations about your product because of our concern that people be able to easily and quickly operate a safety belt in an emergency. As the agency said last year on the related topic of the force level necessary to operate buckles in child restraints:; >>>The agency's safety concerns over child restraint buckle forc release and size stem from the need for convenient buckling and unbuckling of a child and, in emergencies, to quickly remove the child from the restraint. This latter situation can occur in instances of post-crash fires, immersions, etc. A restraint that is difficult to disengage, due to the need for excessive buckle pressure or difficulty in operating the release mechanism because of a very small release button, can unnecessarily endanger the child in the restraint and the adult attempting to release the child. (50 FR 33722, August 21, 1985).<<<; In addition, use of your product can be affected by sectio 108(a)(2)(A) of the Vehicle Safety Act. That section prohibits commercial businesses from knowingly tampering with devices or elements of design installed in a vehicle in compliance with the Federal motor vehicle safety standards. One requirement of Standard No. 209, *Seat Belt Assemblies*, is that the pushbutton release for a safety belt must have a a (sic) minimum area for applying the release force. Installation of your device by a commercial business could be prohibited since it apparently would substantially reduce the minimum area available for applying the release force to the safety belt pushbutton. In addition, Standard No. 302, *Flammability of Interior Materials*, requires new safety belts to meet a flammability resistance requirement. Thus, although Standard No. 302 does not directly apply to aftermarket equipment, commercial businesses could not install your device if it would mean that the safety belt no longer meet (sic) the flammability resistance requirements of Standard No. 302.; The prohibition of section 108(a)(2(A) (sic) does not apply t individual vehicle owners who may install or remove any items of motor vehicle equipment regardless of its effect on compliance with Federal motor vehicle safety standards. However, our policy is to encourage vehicle owners not to remove or otherwise tamper with vehicle safety equipment. Installation of your product by any person could be inconsistent with that policy.; If you have any further questions, please let me know. Sincerely, Erika Z. Jones, Chief Counsel

Dear Senator Miller: Thank you for your letter of August 13, 1968, calling my attention t Mr. Paul Johnston's comments and suggestions on the requirements for school bus signal lamps as specified in Motor Vehicle Safety Standard No. 108.; As Mr. Johnston pointed out, Standard No. 108, effective January 1 1969, provides for optional use of either the eight-lamp or four- lamp signal system. This optional provision was adopted after careful consideration of the comments and recommendations which were received in response to the Notice of Proposed Rule Making as published in the *Federal Register* on February 3, 1967. The 'Minimum Standards for School Buses', as published by the National Conference on School Transportation, and the regulations governing minimum standards for school buses in various states were also considered during development of the optional provision for signal lamp systems. Results of our studies and investigations indicated that approximately forty states were using either the four-lamp or eight-lamp signal system. Other states were using the adopted system with only minor variations in the installation and operational requirements.; Standard No. 108, effective January 1, 1969, was published in th *Federal Register* on December 16, 1967. Under the procedural rules of the Federal Highway Administration, any person adversely affected by this order may petition the Administrator under Part 216, Subchapter B, Section 216.31 or Section 216.35, published in the *Federal Register* on November 17, 1967, a copy of which is enclosed. No petition of the adopted requirements for school bus signal lamps has been filed.; Although we do not dispute the safety benefits which Mr. Johnsto claims for a six-lamp system, I must emphasize that our long-range objective is the adoption of one nationwide system. Even with the presently adopted systems, a motorist could be faced with the problem of interpreting two sets of signals during a very short time period. This problem will become more prevalent with the anticipated increase in rapid interstate traffic. To permit the use of a third optional system, six-lamp or other, would further complicate the situation.; Standard No. 108 applies only to new school buses manufactured on o after January 1, 1969. Retrofitting of buses presently in operation is not required. Since Iowa's fleet of buses is presently equipped with a six-lamp system, it appears that considerable data on the effectiveness of this system could be accumulated from this fleet during the next several years, or until such time that a single nationwide system is proposed. We will be pleased to carefully review and consider any such data which Mr. Johnston can provide in the future.; In summary, it is the position of this Bureau that the provision o Standard No. 108 permitting optional use of either the four-lamp or eight-lamp signal system is reasonable, practicable and in the interest of highway safety. Therefore, we do not believe that a change in this provision to permit optional use of a third or six-lamp system is justified.; We have reviewed our files with respect to the written and persona contacts Mr. Arthur Roberts, Director of Pupil Transportation, has had with this Bureau.; This review indicates that the correspondence from Mr. Roberts wa submitted in response to the Notice of Proposed Rule Making on Standard No. 112 (subsequently combined with Standard No. 108) as published in the *Federal Register* on February 3, 1967. It is not the practice of the Bureau to reply individually to the numerous responses received from published rule making notices, which often run to thousands of pages. However, a summary of the comments represented by the responses and the disposition of these comments is presented in the preamble to Standard No. 108 as published in the *Federal Register* on December 16, 1967. With respect to Mr. Roberts' visit on May 7, 1968, the topics of discussion related primarily to the technical requirements of Standard No. 108 and other information relative to the merits of converging Iowa's school buses to either the four-lamp or eight- lamp system. Our understanding was that Mr. Roberts received the information he was seeking at the time of his visit and that no follow-up correspondence was necessary on our part.; Sincerely, William Haddon, Jr., M.D., Director

"Dear Mr. Littler: This responds to your FAX and phone call of July 30 1993 to Mary Versailles of my office. Your FAX enclosed information on a vehicle, the AMF Invader, which is built on a remanufactured MCI chassis, and advertised and sold as a new vehicle. You do not believe that such a vehicle should be considered a new vehicle. As Ms. Versailles explained on the phone, we can explain whether such a vehicle would be considered a new vehicle for purposes of laws and regulations administered by this agency, and the implications of such a determination. I suggest you also contact the Federal Trade Commission concerning whether it is appropriate to advertise this vehicle as new. To determine whether this vehicle can be titled and registered as new, you would have to contact the various states concerning their laws. By way of background information, the National Highway Traffic Safety Administration (NHTSA) is authorized under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq., Safety Act) to issue Federal motor vehicle safety standards that apply to the manufacture and sale of new motor vehicles and new items of motor vehicle equipment. Section 108(a)(1)(A) of the Safety Act (15 U.S.C. 1397(a)(1)(A)) prohibits any person from manufacturing, introducing into commerce, selling, or importing any new motor vehicle or item of motor vehicle equipment unless the vehicle or equipment item is in conformity with all applicable safety standards. NHTSA, however, does not approve motor vehicles or motor vehicle equipment, nor does it endorse any commercial products. Instead, the Safety Act establishes a self-certification process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. After a vehicle's first retail sale, a provision affecting its modification is section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1397(a)(2)(A)) which 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. It is possible that modifications on an existing vehicle may be so substantial that the resulting vehicle would be a new vehicle for purposes of compliance with the safety standards. In this case, the new vehicle would be required to be certified by its manufacturer as complying with all applicable safety standards in effect on its date of manufacture, just like every other new vehicle. This date would be the date such modifications were completed. The agency has stated that a bus built with a new body is not considered a 'new' vehicle if, at a minimum, the engine, transmission, and drive axle(s) are not new and at least two of these three listed components are taken from the same used vehicle (see, for example, August 11, 1987 letter to Mr. Ernest Farmer). The agency has also stated that a bus constructed from an old body and a new chassis is a new vehicle (see, for example, July 17, 1981 letter to Mr. Larry Louderback). When neither the body nor the chassis are completely new, the agency looks to see if the vehicle has so deviated from the original components and attributes that it may be considered a new vehicle, and one for which compliance with the safety standards is legally required, or whether it has retained a sufficient number of components and characteristics to be considered a used vehicle (see, for example, April 22, 1991 letter to Mr. Kent Morris). You enclosed an article titled 'The New Invader' from the August 1993 issue of National Bus Trader magazine. The manufacturing process for the Invader is described beginning on page 14. Page 16 of this article states, 'the Invader is supplied with a new engine,' but the article does not contain enough information to determine whether the vehicle, which includes both new and old parts, would be considered new. If the Invader has a new body, NHTSA would considered the vehicle to be new if the chassis lacks the used components referenced in the Farmer letter. Any new vehicle must be certified as complying with all applicable safety standards in effect on the date of manufacture before the vehicle can be sold in the United States. I hope you find this information helpful. If you have any other questions, please contact Mary Versailles at this address or by phone at (202) 366-2992.

Dear Mr. Westlake: This is in reply to your letter of February 25, 1985, to Mr. Stephe Wood of this office asking the following three questions about rebuilding and remanufacturing heavy duty trucks.; >>>'1) When rebuilding a used truck with a glider kit, it is ou understanding that the process is considered 'rebuilding' when the three major components (engine, transmission and rear axle) are reused in the rebuilding process. If one or more of these major components is new, does the production of the truck chassis change its legal character from 'rebuilding' to 'first stage manufacturer'?'<<<; Neither the National Traffic and Motor Vehicle Safety Act ('the Act' nor the Federal Motor Vehicle Safety Standard ('safety standards') contain the terms 'rebuilding' and 'first stage manufacturer'. Your question, however, is clear: when new and used components are used in rebuilding a heavy truck, at what point does the truck become a 'new' vehicle which must comply with all safety standards that apply to trucks.; The agency's regulation on *Combining new and used components*, 49 CF 571.7(e), provides:; >>>'When a new cab is used in the assembly of a truck, the truck wil be considered newly manufactured for purposes of compliance with the safety standards and other provisions of the Act unless the engine, transmission, and drive axle(s) (as a minimum) of the assembled vehicle are not new, and at least two of these components were taken from the same vehicle'.<<<; Thus, in terms of your question, if the three major components ar reused in the rebuilding process and at least two of the three came from the same vehicle, the Federal motor vehicle safety standards do not apply even if a new cab is used. But if one of the three components is new, or if all are used and came from three different motor vehicles, then the standards apply and the truck must meet them, and be certified as meeting them, upon final assembly.; Your reference to 'first stage manufacturer' implies that there may b rebuilding fact situations in which the process is completed by a person other than the manufacturer who initiated it. If the rebuilt truck is 'new', then its assemblers are subject to 49 CFR Part 568 *Vehicle (sic) Manufactured in Two or More Stages*. If the truck meets the definition of 'incomplete vehicle', then the 'incomplete vehicle manufacturer' is required to furnish the specified compliance information necessary for certification to the 'intermediate stage manufacturer' or the 'final stage manufacturer' as the case may be (sec. 568.3).; >>>'2) When a truck chassis is built by a dealer and legally classifie as 'new manufacturing' what federal regulations must be complied with that do not apply when the vehicle is considered rebuilt?'<<<; As indicated above, the truck must be completed to comply with al safety standards that apply to trucks and be certified by its assembler as so conforming in accordance with Part 567 *Certification*. If more than one party is involved in the remanufacturing process, each party is subject to Part 568. In addition, any party remanufacturing a truck that must be certified as conforming is required to file a statement in the form prescribed by Part 566 *Manufacturer Identification*.; >>>'3) What penalties exist for failing to comply with these Federa regulations?'<<<; As provided by section 109(a) of the act, any person violating an provision of the Act or a regulation issued thereunder is subject to a civil penalty of up to $1000 for each violation, up to $800,000 for any related series of violations. In addition, under Section 110(a) of the Act, the agency may seek to restrain the manufacture, sale, offer for sale, introduction, or delivery for introduction into interstate commerce of any rebuilt truck that should have met Federal motor vehicle safety standards but in fact did not do so. Also, section 154 of the Act requires manufacturers to conduct recall campaigns and remedy any non-compliances with applicable safety standards.; I hope this information is helpful. Sincerely, Jeffrey R. Miller, Chief Counsel

Ms. Linda B. Kent
Senior Account Executive
Market Development
Fasson Specialty Division
250 Chester Street
Painesville, OH 44077

Dear Ms. Kent:

Thank you for your letter requesting an interpretation of whether the use of a product on motor vehicles would violate Standard No. 205, Glazing Materials (49 CFR /571.205). This product, called "Contra Vision," is designed to display messages or advertising materials on windows and other clear surfaces, so that viewers on one side of the clear surface will see the message displayed, while viewers on the other side of the surface will see an essentially transparent surface without any message visible. According to your letter, this product "will be used for promotional signage in store windows, but also has application in rear taxicab windows, as well as rear and side windows of city buses." You asked for our opinion of whether this product complies with Standard No. 205.

Some background on how Federal motor vehicle safety laws and regulation affect this product 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 new items of motor vehicle equipment. NHTSA, however, does not approve or certify any vehicles or items of equipment, nor do we endorse any commercial products or processes. Instead, the Safety Act specifies that each manufacturer itself must certify that its products meet all applicable safety standards. The agency periodically tests vehicles and items of equipment for compliance with the standards, and also investigates alleged defects related to motor vehicle safety and alleged violations of other statutory provisions.

Your letter indicates that you are already aware that NHTSA has issued a safety standard that applies to the windows installed in motor vehicles. Specifically, Standard No. 205 requires that all new vehicles and all new glazing materials for use in motor vehicles must comply with certain performance requirements. Among the requirements set forth in Standard No. 205 are specifications for minimum levels of light transmittance. A minimum of 70 percent light transmittance is required in glazing areas requisite for driving visibility, which includes all windows in passenger cars. In trucks and buses, the windshield and windows to the immediate right and left of the driver and the rearmost window, if the latter is used for driving visibility, are considered to be requisite for driving visibility, and therefore subject to the 70 percent minimum light transmittance requirement.

Your letter did not provide any information on the light transmittance that would be measured through glazing with Contra Vision installed on it. The combination of the glazing material and the Contra Vision must allow at least 70 percent light transmittance to comply with the requirements of Standard No. 205. No manufacturer or dealer is permitted to install Contra Vision on the glazing materials on new vehicles, unless the manufacturer or dealer certifies that the vehicle continues to comply with the 70 percent minimum light transmittance and other requirements of Standard No. 205.

After a vehicle is first sold to a consumer, modifications to the vehicle are affected by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits any manufacturer, dealer, distributor, or repair business from "rendering inoperative" any device or element of design installed in a vehicle in compliance with any safety standard. This provision of the law means that no manufacturer, dealer, distributor, or repair business could install Contra Vision if the addition of Contra Vision to the glazing would result in a light transmittance of less than 70 percent, or otherwise cause the vehicle to no longer comply with the applicable requirements of Standard 205. Violations of this "render inoperative" prohibition can result in Federal civil penalties to the manufacturer, dealer, distributor, or repair business of up to $1000 for each noncomplying installation.

Section 108(a)(2)(A) of the Safety Act does not affect vehicle owners. Hence, vehicle owners themselves may install Contra Vision or any other product on the glazing of their vehicle, regardless of whether the installation causes the vehicle to no longer comply with Standard No. 205. Individual States have the authority to regulate the operational use of vehicles by their owners, and, therefore, have the authority to regulate or preclude individual owner modifications to the glazing of their vehicles.

I have enclosed an information sheet that summarizes the relationship between Federal auto safety laws and motor vehicle window tinting. I hope this information is helpful. If you have any further questions or need any additional information about this topic, please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.

Sincerely,

Stephen P. Wood Acting Chief Counsel

TEXT: Dear Ms. Kent:

Thank you for your letter requesting an interpretation of whether the use of a product on motor vehicles would violate Standard No. 205, Glazing Materials (49 CFR @ 571.205). This product, called "Contra Vision," is designed to display messages or adver tising materials on windows and other clear surfaces, so that viewers on one side of the clear surface will see the message displayed, while viewers on the other side of the surface will see an essentially transparent surface without any message visible. According to your letter, this product "will be used for promotional signage in store windows, but also has application in rear taxicab windows, as well as rear and side windows of city buses." You asked for our opinion of whether this product complies with Standard No. 205.

Some background on how Federal motor vehicle safety laws and regulation affect this product 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 n ew items of motor vehicle equipment. NHTSA, however, does not approve or certify any vehicles or items of equipment, nor do we endorse any commercial products or processes. Instead, the Safety Act specifies that each manufacturer itself must certify th at its products meet all applicable safety standards. The agency periodically tests vehicles and items of equipment for compliance with the standards, and also investigates alleged defects related to motor vehicle safety and alleged violations of other statutory provisions.

Your letter indicates that you are already aware that NHTSA has issued a safety standard that applies to the windows installed in motor vehicles. Specifically, Standard No. 205 requires that all new vehicles and all new glazing materials for use in moto r vehicles must comply with certain performance requirements. Among the requirements set forth in Standard No. 205 are specifications for minimum levels of light transmittance. A

minimum of 70 percent light transmittance is required in glazing areas requisite for driving visibility, which includes all windows in passenger cars. In trucks and buses, the windshield and windows to the immediate right and left of the driver and t he rearmost window, if the latter is used for driving visibility, are considered to be requisite for driving visibility, and therefore subject to the 70 percent minimum light transmittance requirement.

Your letter did not provide any information on the light transmittance that would be measured through glazing with Contra Vision installed on it. The combination of the glazing material and the Contra Vision must allow at least 70 percent light transmit tance to comply with the requirements of Standard No. 205. No manufacturer or dealer is permitted to install Contra Vision on the glazing materials on new vehicles, unless the manufacturer or dealer certifies that the vehicle continues to comply with th e 70 percent minimum light transmittance and other requirements of Standard No. 205.

After a vehicle is first sold to a consumer, modifications to the vehicle are affected by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397 (a)(2)(A)). That section prohibits any manufacturer, dealer, distributor, or repair business from "rendering inoperative" any device or element of design installed in a vehicle in compliance with any safety standard. This provision of the law means that no manufacturer, dealer, distributor, or repair business could install Contra Vision if the addition of Cont ra Vision to the glazing would result in a light transmittance of less than 70 percent, or otherwise cause the vehicle to no longer comply with the applicable requirements of Standard 205. Violations of this "render inoperative" prohibition can result i n Federal civil penalties to the manufacturer, dealer, distributor, or repair business of up to $ 1000 for each noncomplying installation.

Section 108(a)(2)(A) of the Safety Act does not affect vehicle owners. Hence, vehicle owners themselves may install Contra Vision or any other product on the glazing of their vehicle, regardless of whether the installation causes the vehicle to no longe r comply with Standard No. 205. Individual States have the authority to regulate the operational use of vehicles by their owners, and, therefore, have the authority to regulate or preclude individual owner modifications to the glazing of their vehicles.

I have enclosed an information sheet that summarizes the relationship between Federal auto safety laws and motor vehicles window tinting. I hope this information is helpful. If you have any further questions or need any additional information about thi s topic, please fee free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.

Sincerely,

Mr. Doug Cole Director of Public Relations and Membership National Van Conversion Association, Inc. 2 West Main Street, Suite 2 Greenfield, IN 46140

Dear Mr. Cole:

Thank you for your letter of December 2, 1985 to Stephen Oesch of my staff concerning how our regulations would affect the placement of a national Van Conversion Association (NVCA) certification decal on vehicle windows by a van conversion company. The material enclosed with your letter explains that the NVCA certification program is a voluntary effort by the van conversion industry to set minimum safety and quality standards for its products. You explained that the decal, which has a diameter of 2 1/2 inches, would be placed on the lower corner of the passenger's side of the windshield by a manufacturer whose products conform to the NVCA program.

Placement of the decals on a vehicle's windshield would be affected by 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 the windshield in motor vehicles).

Part 567, Certification, of our regulations requires each vehicle manufacturer to place a plate within the vehicle certifying that the vehicle conforms to all applicable Federal motor vehicle safety standards. A person, such as a van converter, who makes significant modifications to a vehicle prior to its first sale to a consumer is considered a vehicle alterer under our regulations. Under Part 567.7, an alterer must also add a plate to the vehicle certifying that the vehicle, as altered, still continues to conform to all applicable Federal motor vehicle safety standards. Thus, no manufacturer or alterer is permitted to install solar films and other sun screening devices or other opaque materials in new vehicles without certifying that the vehicle continues to be in compliance with the light transmittance and other requirements of the standard.

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 or other opaque material for the owner of the vehicle, if the device would cause the window not to meet the requirements of Standard No. 205. Violation of section 108 (a) (2) (A) can result in Federal civil penalties of up to $1,000 for each violation.

We have not previously ruled on whether these prohibitions apply to the installation of State vehicle inspection and private industry regulatory decals by commercial businesses. In general, these decals are small in size and placed in locations which minimize the obstruction, if any, to the driver's vision. In contrast, tinting films and other sun screening devices are generally applied to the entire window and thus can substantially obscure the driver's vision if they do not meet the light transmittance and other performance requirements of the standard. As with State regulatory decals, your proposed decal is small in size and would be placed in the lower right corner of the vehicle windshield, an area which should minimize any possible obstructing of the driver's vision. Given these considerations, we would consider the placement of the NVCA decal in the lower right hand corner of the windshield to be merely a technical violation of Standard No. 205, and would exercise our prosecutorial discretion and not bring an enforcement action.

I hope this information is of assistance to you. If you have any further questions, please let me know.

Sincerely,

Erika Z. Jones Chief Council

December 2, 1985

Mr. Steve Oeshe NHTSA, Office of the Chief Council 400 7th Street South West Washington, D.C. 20590

Dear Steve:

Will you please provide me a written statement, from your department, that the placement of our Certification decals are not in violation of any Federal Safety Standards?

I have enclosed a rough drawing showing the placement of the decal, on the inside lower passenger side of the windshield. Also enclosed is our information packet about National Van Conversion Association's Van Conversion Manufacturer Certification program.

If you have any questions about the program, or if I can be of service, please call on me.

Sincerely,

Doug Cole Director of P.R. and Membership
