NHTSA Interpretation File Search

Overview

NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies. 

Understanding NHTSA’s Online Interpretation Files

NHTSA makes its letters of interpretation available to the public on this webpage. 

An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.

  • Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
  • Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
  • The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
  • Some combination of the above, or other, factors.

III P.O. Box 817 Mill Valley
CA 94942;

"Dear Mr. Zang: This responds to your letter asking about governmen rules applicable to your product, which you describe as an aftermarket child's car seat cover made out of a plastic-coated fabric. In particular, you were concerned about flammability restrictions that would be applicable to your product. I am pleased to have this opportunity to explain our requirements to you. After providing background information, I will answer the specific questions raised in your letter. By way of background information, NHTSA is authorized to issue Federal Motor Vehicle Safety Standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. 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. The agency periodically tests new vehicles and items of equipment for compliance with the standards. In response to your question, there are currently no Federal motor vehicle safety standards (FMVSS's) that directly apply to the product you wish to manufacture. Under the authority of the Safety Act, NHTSA has issued Standard No. 213, Child Restraint Systems, which specifies requirements for child restraint systems used in motor vehicles and aircraft. However, Standard No. 213 applies only to new child restraint systems and not to aftermarket components of a child restraint system, such as an aftermarket seat cover. I note, however, that there are other Federal requirements that indirectly affect your manufacture and sale of your product. Under the Safety Act, your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you are subject to the requirements in 151-159 of the Safety Act concerning the recall and remedy of products with safety related defects. I have enclosed an information sheet that briefly describes those responsibilities. In the event that you or NHTSA determines that your cover contains a safety-related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge. Manufacturers, distributors, dealers, and motor vehicle repair businesses are subject to 108(a)(2)(A) of the Safety Act, which states: '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 or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard ....' A child restraint has elements of design that could be rendered inoperative by a child seat cover. Standard No. 213 sets flammability resistance requirements for materials used in a child restraint system. (See S5.7 of Standard No. 213, referencing Standard No. 302, 'Flammability of Interior Materials.') While it appears unlikely that persons in the aforementioned categories would be installing your product, if they were to install it, they should ensure that they do not compromise the safety protection provided by the child restraint system. The 'render inoperative' prohibition of 108(a)(2)(A) does not apply to the actions of vehicle owners in adding to or otherwise modifying their vehicles or items of motor vehicle equipment. Thus, if your seat cover were placed on restraints by the restraint owners, your product need not meet any FMVSS's. Nevertheless, in the interest of safety, we suggest you consider conforming your product to a flammability resistance standard equivalent to Standard No. 302. I will now take this opportunity to answer your specific questions. Question One 1. Where can the fabric be tested? The agency does not recommend any test laboratory. However, the following laboratories have conducted similar tests for this agency. Commercial Testing Co Detroit Testing Laboratory 1215 S. Hamilton Street P.O. Box 869 Dalton, GA 30722-0985 Warren, MI 48090-0869 Phone: (404) 278-3935 Phone: (313) 754-9000 Fax: (404) 278-3936 Fax: (313) 754-9045 United States Testing Co. Engineering Services Division 291 Fairfield, NJ 07006 Phone: (201) 575-5252 Fax: (201) 575-8271 Question Two 2. What are the test specifications? As explained above, Standard No. 302 specifies the Federal motor vehicle safety standards applicable to flammability resistance. This standard does not directly apply to aftermarket products such as a seat cover for a child restraint. However, we have enclosed a copy of Standard No. 302 for your information. Question Three 3. Are these questions something that are already available from the factory? We are not certain what information you wished to obtain by this question. We assume that you were asking whether a manufacturer of a product subject to Standard No. 302 can rely on the assurances from the fabric manufacturer that the material meets the standard's flammability requirements. The manufacturer of the product (e.g., a new child restraint system) would be responsible for exercising due care in certifying that the product meets all applicable FMVSS's. The manufacturer of the product would thus be responsible for ensuring that its reliance on the fabric manufacturer's assurances were reasonable and that the assurances were bona fide. Question Four 4. Whether the packaging can state that the fabric has been tested and found to be within compliance with government regulations. Only motor vehicles and motor vehicle equipment that are subject to and that meet the FMVSS's may be certified as complying with those standards. NHTSA does not permit manufacturers of products that are not subject to the FMVSS's to certify to those standards because consumers might be confused or misled about a statement that a product complies with a standard when in fact no standard applied. Accordingly, since no FMVSS applies to an aftermarket child seat cover, you must not state on the packaging that the fabric of your product complies with the FMVSS's. Question Five 5. Seeks any other government regulations for children's products. We are not aware of any other Federal government agency that regulates items of motor vehicle equipment. More generally, please be aware that the United States Consumer Product Safety Commission regulates certain consumer products used by children. You may wish to contact that agency at (301) 492-6580 for information about their statutes and regulations related to children's products. I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel Enclosure";

"Dear Ms. Jones: This responds to your letter to Ms. Deirdre Fujita o my staff asking about safety regulations, particularly for flammability resistance, for a device you call a 'Toddler Traveler pillow.' According to promotional literature you sent with your letter, the Toddler Traveler pillow is used with a child booster seat to provide 'padded comfort and support' to a child sleeping in the booster. The pillow provides a surface the child could lean on while sleeping. By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the authority to issue Federal motor vehicle safety standards (FMVSSs) for new motor vehicles and new items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. Instead, Congress has established a 'self-certification' process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. The following represents our opinion based on the information set forth in your letter and promotional literature. Currently there are no Federal motor vehicle safety standards (FMVSSs) that directly apply to the Toddler Traveler pillow. Our standard for 'child restraint systems,' FMVSS 213, applies to 'any device except Type I or Type II seat belts, designed for use in a motor vehicle or aircraft to restrain, seat, or position children who weigh 50 pounds or less.' The standard does not apply to accessory items, such as a pillow that is used with a child booster seat. Our standard for flammability resistance, FMVSS 302, applies to new motor vehicles and to new child restraint systems. It does not apply to child restraint accessory items. While no FMVSS applies to the Toddler Traveler pillow, your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you are subject to the requirements of 49 U.S.C. 30118-30121 concerning the recall and remedy of products with safety related defects. I have enclosed a copy of those defect provisions, as well as an information sheet that briefly describes those and other manufacturer responsibilities. In the event you or NHTSA determines that your product contains a safety-related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge. In addition, while it is unlikely that the Toddler Traveler pillow would be installed by a motor vehicle manufacturer, distributor, dealer or repair business, 49 U.S.C. 30122 prohibits those businesses from installing the device if the installation 'makes inoperative' compliance with any safety standard. No commercial business listed in 30122 can install a Toddler Traveler pillow if the product undermines the vehicle's compliance with a safety standard, including Standard 302 for flammability resistance. The prohibition of 30122 does not apply to individual owners who install equipment in their own vehicles. Thus, individual owners may install any item of motor vehicle equipment regardless of its effect on compliance with Federal motor vehicle safety standards. However, NHTSA encourages vehicle owners not to degrade the safety of their vehicles. Before closing, we would like to comment on a further issue, one that you and Ms. Fujita discussed on the telephone. The advertising literature you enclosed with your letter described the Toddler Traveler pillow as being suitable for use with children ages '18 months to 4 years.' We believe this description is potentially confusing concerning the use of booster seats by young children. Booster seats are intended to be used as a transition to safety belts by older children who have outgrown convertible seats (ideally, over 40 pounds and 4 years). A booster seat is not designed to restrain young children, and under a requirement we recently adopted, cannot now be recommended for children under 30 pounds. Stating '18 months to 4 years' may be mistaken to imply that, with your pillow, a booster seat could be used to restrain a child as young as 18 months. To avoid any possible misunderstanding, we suggest that the phrase on recommended use of the pillow should refer to older children, such as those 'over 4 years.' One further note in closing. You said that a year ago, Ms. Fujita told you 'there are no codes to govern' your product. Ms. Fujita is concerned that you might believe you were given an oral interpretation of how our requirements apply to your product. Please note that we cannot give oral interpretations. Ms. Fujita provided you a copy of an interpretation we'd issued in the past on a child seat pillow accessory, while indicating that an interpretation of which requirements apply to your product must be from us in writing. (This letter comprises that interpretation.) We regret any confusion on this issue. I hope this information is helpful. If you have any other questions, please feel free to contact Ms. Fujita at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel Enclosures";

"Dear Mr. Sazio: This responds to your letter concerning th application of our regulations and Federal motor vehicle safety standards to your company's manufacture of 'convertible vinyl tops for Jeeps and similar vehicles.' I regret the delay in responding. You asked which Federal safety standards apply to these convertible tops that you sell in both the new vehicle market and the aftermarket. You were especially interested in standards for 'windows and door handles.' There are two Federal safety standards (copies enclosed) that would apply to your product: (1) Standard No. 205, Glazing Materials, and (2) Standard No. 302, Flammability of Interior Materials. While the brevity of the description of your product makes it difficult for us to determine whether our standard for door handles (Standard No. 206, Door Locks and Door Retention Components) applies, we believe that the standard does not apply to your product because the tops, which apparently incorporate doors, are readily removable. By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the authority under the National Traffic and Motor Vehicle Safety Act (copy enclosed) to establish Federal motor vehicle safety standards for new motor vehicles and items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment. 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. This process requires each manufacturer to determine in the exercise of due care that its products meet all applicable Federal requirements. The agency periodically tests vehicles and equipment for compliance with the standards, and also investigates other alleged safety-related defects. If you or the agency determines that a noncompliance or safety-related defect exists, you are obligated to notify purchasers of your product and remedy the problem without charge. Manufacturers who fail to provide notification of or remedy for a defect or noncompliance may be subject to a civil penalty of up to $1,000 per violation. (A general information sheet describing manufacturers' responsibilities under the Safety Act is enclosed.) The Safety Act defines the term 'motor vehicle equipment' as follows: 'Motor vehicle equipment' means any system, part, or component of a motor vehicle as originally manufactured or any similar part or component manufactured or sold for replacement or improvement of such system, part, or component or as any accessory or addition to the motor vehicle ...' (/102(4)) This definition includes the product your company manufactures since the convertible tops are components manufactured and sold either as a replacement or improvement of the convertible top or as an addition to vehicles that have no existing top. Since your product is considered an item of motor vehicle equipment, S.C. Manufacturing Inc., as the manufacturer of the equipment, must ensure that the convertible tops comply with all applicable Federal motor vehicle safety standards and contain no safety-related defects. If your product contains glazing material, Standard No. 205 (49 CFR /571.205, Glazing Materials) directly applies to that glazing material. Standard No. 205 is an equipment standard which sets performance requirements for glazing materials used in new motor vehicles and glazing materials sold as items of motor vehicle equipment, including glazing used in convertible tops. Any glazing in the convertible tops that your company manufactures for new or used vehicles must therefore conform to the applicable specifications set forth in Standard No. 205. The standard establishes both performance requirements, including those regulating the light transmittance and abrasion resistance of glazing, and labeling requirements applicable to the glazing used in your product. If your convertible top is added to a new vehicle, i.e., before the vehicle is sold for the first time to a consumer, then it must comply with Standard No. 302, Flammability of Interior Materials (49 CFR /571.302). Standard No. 302 applies to certain vehicle occupant compartment components, including convertible tops, on new completed motor vehicles. Persons selling new vehicles equipped with your convertible top must ensure that the vehicles, including your top, conforms to Standard No. 302. Generally speaking, while the requirements of Standard No. 302 apply to convertible tops incorporated in new vehicles, they do not apply to convertible tops added to used vehicles, i.e., vehicles which have been sold for the first time to a consumer. Under this general rule, you are permitted to sell aftermarket convertible tops that do not comply with Standard No. 302 to vehicle owners who will add them to their used vehicles even if the addition of the top by the vehicle owners caused the vehicles to no longer comply with Standard No. 302. This general rule is, however, limited by the application of the provisions of /108(a)(2)(A) of the Vehicle Safety Act. That section specifies: '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 or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard ...' This section requires manufacturers, distributors, dealers or motor vehicle repair businesses (i.e., any person holding him or herself out to the public as in the business of repairing motor vehicles or motor vehicle equipment for compensation) installing your top on new or used vehicles to ensure that the addition of the apparatus would not negatively affect the compliance of any component or design on a vehicle with applicable Federal safety standards. For example, the commercial entity must ensure that the addition of the top does not degrade from the safety provided by flammable-resistant materials in the vehicle's interior compartment which have been installed in accordance with Standard No. 302. Installation of rapidly burning materials could vitiate the compliance of the materials which were present in the vehicle at the time of its sale to the first consumer and were certified as meeting FMVSS No. 302. Section 109 of the Act specifies a civil penalty of up to $1,000 for each violation of section 108. You should note that section 108(a)(2)(A) is not limited to Standard No. 302, but applies also to any modification of Federally-required safety systems or devices on new or used vehicles. Section 108(a)(2)(A) prohibits rendering inoperative the compliance of devices or elements of design with any applicable Federal safety standard. Thus, a commercial entity would be permitted to install your product only if the modification would not destroy or degrade from a vehicle's compliance with any applicable Federal requirements, such as those for lamps and reflective devices (Standard No. 108). Standard No. 206 applies to new vehicles, but not to new aftermarket motor vehicle equipment. Therefore, the doors on aftermarket Jeep top covers would not have to meet the standard. Further, doors on new Jeep vehicles would not have to meet the standard if they are 'designed to be easily attached to or removed from' the vehicle, as provided in paragraph S4 of Standard No. 206. To summarize the above discussion, any glazing in the convertible tops you manufacture must meet applicable requirements of Standard No. 205 regardless of whether the tops are sold in the aftermarket or to new vehicle purchasers. The effect of Standard No. 302 on your product depends on the circumstances surrounding installation of the product in new and used motor vehicles. If the convertible top does not meet Standard No. 302, the top cannot be installed in vehicles by any commercial business listed in /108(a)(2)(A) of the Safety Act. However, these convertible tops may legally be installed in vehicles by the owners of the vehicles. Your company would still have the responsibility under the Vehicle Safety Act to recall and remedy its products which are determined to contain a defect relating to motor vehicle safety, even if the convertible tops were installed by vehicle owners themselves. I hope this information is helpful. In addition to the materials described above, I have also enclosed an information sheet describing generally your responsibilities under the Vehicle Safety Act. Please contact my office if we can be of further assistance. Sincerely, Stephen P. Wood Acting Chief Counsel Enclosures";

"Dear Mr. Peterson: This responds to your May 17, 1988 letter to m asking for 'information on petitions filed, concerning the safety problems on trucks.' You also enclosed for the agency's information materials on the product you manufacture called a 'Truk-Hedrest.' According to the brochures you sent, the Truk-Hedrest attaches to the rear window of a vehicle by means of velcro and 'is designed to help protect the head of the driver and passenger of a truck or van in an accident when their head is snapped back against the rear window or bulkhead of a vehicle.' You also enclosed a copy of an August 28, 1987 letter which Mr. Carl Clark of this agency sent you regarding your product. The latter part of this letter addresses statements in your brochures relating to our regulations and the Truk-Hedrest. The National Highway Traffic Safety Administration (NHTSA) shares your concern for light truck safety and is currently reviewing a number of actions intended to improve the protection for occupants of such vehicles. This review has been described in detail in the enclosed reports to Congress issued by NHTSA in May 1987 ('Light Truck and Van Safety') and April 1988 ('Safety Programs for Light Trucks and Multipurpose Passenger Vehicles'). Among the rulemaking activities considered by NHTSA for light trucks is a possible extension of Safety Standard No. 202, Head Restraints, to those vehicles. The agency is presently reviewing petitions for rulemaking on this subject from Mr. Dale T. Fanzo of Bethel Park, Pennsylvania and Mr. Mark E. Goodson of Lewisville, Texas. I have enclosed copies of these petitions for your information. With regard to the brochures and materials you sent on your product, I would like to first to make it clear that Mr. Clark's letter on the Truk-Hedrest only expressed his personal opinions and interests concerning your product. His letter does not represent any official agency position regarding light truck safety in general or regarding your product in particular. Mr. Clark's letter was neither an approval nor endorsement of your product by this agency. NHTSA does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products. In addition, the agency cannot as a matter of law and will not as a matter of policy determine the extent, if any, of the occupant protection provided by any commercial product apart from the context of an actual enforcement proceeding. Thus, the agency does not concur in any manner with Mr. Clark's assessement that the Truk-Hedrest 'does indeed provide excellent head protection' or with any other statement as to the effectiveness of your product. Second, your brochures imply that the Truk-Hedrest has been shown to help protect against possible neck and head injuries when tested to 'NHTSA guidelines.' NHTSA has neither adopted or even developed guidelines for testing the Truk-Hedrest. Again, in his letter to you Mr. Clark provided only his personal opinion on certain aspects of your product testing program. He expressed no agency recommendations or 'guidelines' for testing a product such as yours 'for rear end collisions up to 50 MPH,' or with bowling balls, since no such guidelines exist. My final clarification concerns the statements in your brochures that the Truk-Hedrest 'Passes MVSS-302 Test for fire and toxic fumes.' Please note that Standard No. 302, Flammability of Interior Materials, addresses only the flammability resistance of vehicle components and not the toxicity of gases from burning materials. With respect to your statement about meeting the FMVSS 302 requirements regarding fire, please note that if the Truk-Hedrest did not in fact meet those requirements and were installed in a vehicle by a motor vehicle manufacturer, distributor, dealer or repair business, there could be a violation of the National Traffic and Motor Vehicle Safety Act. Section 108(a)(2)(A) of the Act prohibits those persons from rendering inoperative any device or element of design installed pursuant to the Federal motor vehicle safety standards. Installation of rapidly burning materials could vitiate the compliance of the materials which were present in the vehicle at the time of its sale to the first consumer and were certified as meeting FMVSS 302. To repeat, in his letter to you Mr. Clark was only expressing his personal opinions and interests concerning your product and made no statements that should be construed as official agency positions. NHTSA does not endorse the Truk-Hedrest nor do we make any determination on the extent, if any, of the occupant protection provided by your product. I regret any confusion that may have resulted from Mr. Clark's letter to you on the Truk-Hedrest. Please contact my office if you have further questions. Sincerely, Erika Z.

"Dear Ms. Jones: This responds to your letter asking for ou concurrence that 103(d) of the National Traffic and Motor Vehicle Safety Act preempts a 'California flammability standard' as that standard applies to child restraint systems. The standard you enclosed is California Business and Professions Code, Division 8, Chapter 3, 19006 and 19161. I apologize for the delay in this response. Because it was not readily apparent from your letter that the California flammability standard applies to child restraint systems, Ms. Fujita of my staff contacted California state officials for more information about the standard. We were informed by Mr. Art Anderson, Chief of the California Highway Safety Office, that California does not have a flammability standard for child restraint systems. Mr. Anderson was aware that Federal Motor Vehicle Safety Standard (FMVSS) No. 302 applies to child restraints by way of S5.7 of FMVSS No. 213, 'Child Restraint Systems.' As you point out, Federal preemption issues would arise if California had a flammability standard for child restraint systems that covered the same aspect of performance as FMVSSs 213 and 302. However, in view of Mr. Anderson's statement that California has no flammability standard for child restraint systems, we need not address those issues today. We hope this information is helpful. Mr. Anderson of the California Highway Safety Office (telephone (916) 445-0527) said he will be happy to answer any questions you might have about California's requirements. If you any further questions about 103(d), please do not hesitate to contact us. Sincerely, John Womack Acting Chief Counsel cc: Art Anderson";

"Dear Ms. Pietra: This responds to your letter asking about safet regulations for a device you call a 'Cair Bag.' You describe the Cair Bag as a 'comfort pillow' for children to rest or sleep on while seated in their vehicle seat belt. You explain that the Cair Bag is an 'under-stuffed styrene pellet bag' that attaches to the lap portion of the vehicle's Type II seat belt with a reinforced velcro and nylon strap. You state that you will recommend the product for children over 50 pounds 'to prevent it from being used as a child restraint system.' By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the authority to issue Federal motor vehicle safety standards for new motor vehicles and new items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. You state in your letter that everyone you spoke to at NHTSA 'felt this was a great product.' To avoid any possible misunderstanding about what agency personnel said about your product, I wish to clarify that NHTSA and agency personnel can not and do not endorse any product, or make commendations about products. If you understood them to say NHTSA approves of or believes your product is 'great,' that is incorrect, and we apologize for any confusion. Turning now to your questions, there is currently no Federal motor vehicle safety standard (FMVSS) that directly applies to the Cair Bag. Our standard for 'child restraint systems,' FMVSS 213, applies to 'any device except Type I or Type II seat belts, designed for use in a motor vehicle or aircraft to restrain, seat, or position children who weigh 50 pounds or less.' (S4 of FMVSS 213) We do not consider the Cair Bag to 'position children' in a manner that a child seat positions children to better use a vehicle's belt system. Rather, the Cair Bag is simply a cushion that a child may lean on. Since your product does not 'restrain, seat, or position' children as a child restraint system, the product is not subject to Standard 213 regardless of the weight of the children for whom you recommend the product. However, we share your concern that the Cair Bag must not be used in place of a child restraint system. We recommend that the product be clearly labeled with information to the consumer that the product is not a child restraint system and must not be used as one. While no FMVSS applies to the Cair Bag, your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you are subject to the requirements of 49 U.S.C. 30118-30121 concerning the recall and remedy of products with safety related defects. I have enclosed an information sheet that briefly describes those and other manufacturer responsibilities. In the event you or NHTSA determines that your product contains a safety-related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge. In addition, while it is unlikely that the Cair Bag would be installed by a motor vehicle manufacturer, distributor, dealer or repair business, 49 U.S.C. 30122 prohibits those businesses from installing the device if the installation 'makes inoperative' compliance with any safety standard. Our FMVSS's require specific levels of performance for the belt system in a vehicle. For example, Standard 208 has requirements that ensure that a vehicle's lap and shoulder belts are installed to distribute the crash forces over the skeletal structure of the occupant. The FMVSS also have requirements for belts to automatically lock and retract, ensuring there is no excessive slack in the belt system. Since the Cair Bag attaches to the lap belt, any person listed in 30122 must ensure that compliance of the belt system with these requirements is not degraded. Also, FMVSS 302 specifies flammability resistance requirements for vehicle interiors. Any person listed in 30122 who installs a Cair Bag must ensure that the product does not vitiate the vehicle's compliance with those flammability resistance requirements. The prohibition of 30122 does not apply to individual owners who install equipment in their own vehicles. Thus, individual owners may install any item of motor vehicle equipment regardless of its effect on compliance with Federal motor vehicle safety standards. However, NHTSA encourages vehicle owners not to degrade the safety of their vehicles. I would like to make a further note in closing. The advertising literature you enclosed with your letter described the Cair Bag as 'The Portable `Air Bag'.' We believe this description could be misleading, because the term 'air bag' is widely recognized as describing an inflatable device that provides substantial occupant protection in frontal impacts. We are concerned that calling your device a 'portable air bag' could mislead some consumers into believing your device offers occupant protection similar to that of a vehicle air bag, which of course, is incorrect. To avoid this potential for confusion, please refrain from describing your device as an 'air bag.' I hope this information has been helpful. If you have any other questions, please contact Deirdre Fujita of my staff at this address or by phone at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel Enclosure";

Dear Ms. Sparks:

This responds to your May 7, 2020 email asking about adding “driver shields” to transit buses and vans. You explain that you are developing a driver’s shield assembly to provide to your customers in the transit industry in an effort to protect drivers from the Coronavirus Disease 2019 (COVID-19). You describe the shields as being constructed with plexiglass, stainless tubing and fasteners, with a swing out door to give drivers access to the stepwell entry platform and passenger cabin. You ask about the requirements that would apply when adding these shields to vehicles. We appreciate this opportunity to respond.

Background 

By way of background, the National Highway Traffic Safety Administration (NHTSA) is authorized by the National Traffic and Motor Vehicle Safety Act (“Safety Act,” 49 U.S.C. Chapter 301) to issue Federal motor vehicle safety standards (FMVSS) that set performance requirements for new motor vehicles and new items of motor vehicle equipment. NHTSA does not approve motor vehicles or motor vehicle equipment and does not determine whether a product conforms to the FMVSS outside of an agency compliance proceeding. Instead, the Safety Act requires manufacturers to self-certify that their products conform to all applicable FMVSS that are in effect on the date of manufacture. NHTSA also investigates safety-related defects.

Discussion

Our answer below is based on our understanding of the specific information provided in your email and attached documentation. Please note that this interpretation letter does not have the force and effect of law and is not meant to bind the public in any way. NHTSA will make determinations of conformance with the FMVSSs only in the context of an agency enforcement proceeding. This letter is intended only to provide clarity to the public regarding existing requirements under the law, and represents the opinion of the agency on the questions addressed in your email at the time of signature.

After reviewing the information you provided, NHTSA has concluded that the transparent material of the “shield assembly,” located immediately to the right of a driver, is an interior partition composed of motor vehicle “glazing” that must comply with FMVSS No. 205, “Glazing materials.” FMVSS No. 205 establishes minimum performance requirements for glazing materials for use in motor vehicles and motor vehicle equipment and incorporates by reference an industry standard, the American National Standards Institute American National Standard for Safety Glazing Materials for Glazing Motor Vehicles and Motor Vehicle Equipment Operating on Land Highways-Safety Standard (ANSI/SAE Z26.1-1996). FMVSS No. 205 and ANSI/SAE Z26.1 specify performance requirements for various types of glazing (called “Items”), and specify the locations in vehicles in which each item of glazing may be used. FMVSS No. 205 applies to glazing installed in motor vehicles1 prior to first purchase and to aftermarket glazing for use in motor vehicles.

As motor vehicle glazing, the transparent material of your barrier must meet the requirements of FMVSS No. 205 and be certified as meeting that standard by the prime glazing manufacturer, and, if applicable, the manufacturer or distributer who cuts the glazing into components for use in motor vehicles or items of motor vehicle equipment.2 If you, in assembling the barrier, cut the glazing, you must ensure the glazing meets the requirements of FMVSS No. 205, and must certify its compliance pursuant to S6.3 of FMVSS No. 205. On the other hand, if you only assemble the barrier using pre-cut glazing that has been certified by a glazing manufacturer, you are not required to certify the glazing. However, as the manufacturer of the aftermarket barrier, you are responsible for ensuring your product is free from safety-related defects. If you or this agency finds your product to contain a safety-related defect after you market the product, you are responsible for conducting a notice and recall campaign as required under 49 U.S.C. §§ 30118- 30120.

As described in your email, the barrier would be located to the right of the driver. In that location, and for every vehicle type, portions of the glazing would be requisite for driving visibility. Any portion of the glazing that the driver would see through in order to view windows requisite for driving visibility would also be considered requisite for driving visibility. For buses and multipurpose passenger vehicles (MPVs), this would include any window to the immediate right or left of the driver and the front windshield.3 (For passenger cars, all windows are considered requisite for driving visibility.)

 

1 Requirements for glazing vary by vehicle type. You state that the barriers will be installed in buses and “vans.” NHTSA does not use the term “van” when classifying motor vehicles for purposes of FMVSS applicability. If the vehicle in which the barriers will be installed carry more than 10 persons, the vehicle would be classified as a bus under NHTSA’s FMVSS. If the vehicle carries 10 or fewer persons, it would be classified as either a multipurpose passenger vehicle (MPV) or passenger car, depending on whether the vehicle is built on a truck chassis or with special features for occasional off-road operation (49 CFR 571.3). Based on your email, we assume that the vehicles in which the barriers would be installed are not passenger cars. Thus, we assume the vehicles are “buses” or “MPVs.” We assume the vehicles are not trucks. This classification is important for determining the application of the glazing standard to the vehicles.

2 49 CFR 571.205, S6.

3 In a letter to Cris Morgan, NHTSA concluded that low-level glazing on doors to the right or left of the driver are considered windows that are requisite for driving visibility. Therefore, glazing through which the driver would view

Glazing for interior partitions in areas requisite for driving visibility must be of one of the following types of glazing: Item 1, Item 2, Item 4, Item 4A, Item 10, Item 11A, Item 11C,4 Item 14, Item 15A, or Item 15B. Glazing for interior partitions in areas not requisite for driving visibility must be one of the following types of glazing: Item 1, Item 2, Item 3, Item 4, Item 4A, Item 5, Item 10, Item 11A, Item 11B, Item 11C, Item 12, Item 13, Item 14, Item 15A, Item 15B, Item 16A, or Item 16B.

Please note that there may be additional requirements depending on who installs the barrier. If the barrier is installed prior to first vehicle sale, the installer must ensure that, with the barrier installed, the vehicle complies with FMVSS No. 205 and all other applicable FMVSS, and must certify the vehicle as complying with all applicable FMVSS. If the barrier is installed as aftermarket equipment by a manufacturer, distributor, dealer, rental company, or motor vehicle repair business, that entity would be subject to 49 U.S.C. 30122, which prohibits the entity from knowingly making inoperative any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable FMVSS. In either case, the entity installing the barrier should pay particular attention to ensuring that installation of the barrier does not obstruct the driver’s view of the mirrors and/or rearview image required under FMVSS No. 111, “Rear visibility,” impact the vehicle’s compliance with FMVSS No. 302 “Flammability of interior materials,” prevent the driver from readily accessing emergency exits installed in compliance with FMVSS No. 217, “Bus emergency exits and window retention and release,” or impede the driver’s ability to see through the windows needed for driving visibility.5

Apart from requirements that NHTSA administers, the installation of the barrier may be subject to other Federal or State laws or regulations. For example, purchasers or lessees of the vehicles may be subject to the Americans with Disabilities Act (ADA) and the accessibility requirements found at 49 CFR Parts 37 and 38 and may need to ensure that the vehicle they purchase or lease continues to comply with the requirements after the barrier is installed.

these windows would be considered requisite for driving visibility. Letter to Cris Morgan (January 14, 2009), available at https://isearch.nhtsa.gov/files/08-004149--19%20Nov%2008--sa.htm.

4 If the partition is a bullet-resistant shield constructed using Item 11C glazing, the combined parallel luminous transmittance with perpendicular incidence through both the shield and the permanent vehicle glazing is to be at least 60 %.

5 To ensure that installation does not impact the vehicle’s compliance with applicable FMVSS, the installer should be familiar with FMVSS requirements for a vehicle of its type and weight. Please note that installation of a safety barrier in vehicles with a GVWR of 4,536 kg (10,000 pounds) or less may require additional considerations as there are different, and often more stringent, requirements for lighter vehicles.

I hope this information is helpful. If you have any further questions, please feel free to contact Callie Roach of my staff at this address or at (202) 366-2992.

Sincerely,

JONATHAN CHARLES MORRISON

"Dear Mr. Thies: This responds to your letter asking about Federa rules, particularly those for flammability resistance, applicable to your aftermarket product. I apologize for the delay in responding. You state that your product is a sheet of clear vinyl that inhibits the air flow in a van, thus reducing the amount of air to be heated or cooled. You further state that your product does not impair visibility and that it is easily detached and removed by the vehicle owner. This response is based on our understanding of the facts presented in your letter. By way of background information, NHTSA is authorized to issue Federal Motor Vehicle Safety Standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. NHTSA does not, however, approve or certify any vehicles or items of equipment. 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 all applicable safety standards. The agency periodically tests new vehicles and items of equipment for compliance with the standards. In response to your question, you are required to certify that your device complies with Standard No. 205, Glazing Materials (49 CFR 571.205), based on our understanding of your letter. Standard No. 205 applies to new, completed vehicles as well as to glazing sold in the aftermarket. The standard establishes performance requirements for various types of glazing (called 'items') and specifies the locations in vehicles in which each item of glazing may be used. The standard also incorporates by reference 'ANSI Z26,' the American National Standards Institute's 'Safety Code for Safety Glazing Materials for Motor Vehicles Operating on Land Highways.' It appears that your device may be considered an 'interior partition,' which is considered under ANSI Z26 to be item 6 glazing. In addition, if your product were manufactured for a new vehicle, the vehicle would have to be certified as complying with Standard No. 111, Rearview Mirrors and Standard No. 302, Flammability of Interior Materials, in addition to Standard No. 205. However, Standards No. 111 and No. 302 apply only to new vehicles, and not to items of aftermarket motor vehicle equipment. Thus, they do not apply to your product. I note, however, that there are other Federal requirements that indirectly affect the manufacture and sale of your product. Under the Safety Act, your product is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you are subject to the requirements in 151-159 of the Safety Act concerning the recall and remedy of products with safety related defects. I have enclosed an information sheet that briefly describes those responsibilities. In the event that you or NHTSA determines that your product contains a safety-related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge. Manufacturers, distributors, dealers, and motor vehicle repair businesses are subject to 108(a)(2)(A) of the Safety Act, which states: '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 or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard ....' Your vinyl sheet could render inoperative the rearward visibility requirements set forth in Standard No. 111, or the light transmittance requirements set forth in Standard No. 205. In addition, your product could have elements of design that could render inoperative a vehicle's compliance with Standard No. 302, the FMVSS for flammability resistance for materials used in the occupant compartment of motor vehicles. While it appears unlikely that persons in the aforementioned categories would be installing your product, if they were to install it, they must not compromise the rearward visibility or flammability resistance provided by the motor vehicle. The 'render inoperative' prohibition of 108(a)(2)(A) does not apply to the actions of vehicle owners in adding to or otherwise modifying their vehicles or items of motor vehicle equipment. Thus, if your products were placed in vehicles by the vehicle owners, they would not need to meet any FMVSSs. Nevertheless, NHTSA urges vehicle owners not to tamper with or degrade the safety of their vehicles. I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992.

"Dear Mr. Schroeter: This responds to your letter asking fo information about the application of Federal safety standards to a head restraint that attaches to the rear window of pickup trucks. I regret the delay in responding. I hope the following information is helpful. By way of background information, the National Highway Traffic Safety Administration (NHTSA) is authorized by the National Traffic and Motor Vehicle Safety Act to issue Federal motor vehicle safety standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. NHTSA is not authorized to certify or approve motor vehicles or motor vehicle equipment for compliance with our Federal motor vehicle safety standards. Instead, under the National Traffic and Motor Vehicle Safety Act (copy enclosed), each manufacturer of a motor vehicle or item of motor vehicle equipment is responsible for certifying that its products meet all applicable safety standards. The following represents our opinion based on the information provided in your letter. There is currently no Federal motor vehicle safety standard that is directly applicable to the product you wish to manufacture and sell. Our standard for head restraints (Standard No. 202) applies only to completed new passenger cars and not to a head restraint device sold as an item of 'aftermarket' equipment for pickup trucks. However, there are other Federal laws that indirectly affect your manufacture and sale of the head restraint device. Under the Safety Act, your device is considered to be an item of motor vehicle equipment. As a manufacturer of motor vehicle equipment, you are subject to the requirements in sections 151-159 of the Safety Act concerning the recall and remedy of products with defects relating to motor vehicle safety. I have enclosed an information sheet that briefly describes those responsibilities. In the event that you or NHTSA determines that your head restraints contain a safety related defect, you would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge. Safety Standard No. 302, Flammability of Interior Materials (copy enclosed), would also affect your head restraint if your product is installed by a commercial business on either new or used vehicles. A manufacturer installing your head restraint device on a new truck prior to certifying the truck as complying with all applicable Federal motor vehicle safety standards, as required by the Safety Act, has certain responsibilities relating to that obligation to certify. Standard No. 302 establishes flammability resistance requirements for trucks that must be met by certain vehicle components, including head restraints. The new vehicle manufacturer that installs your product on the new vehicle would have to certify the vehicle's compliance with Standard No. 302, and thus would be required to ensure that the head restraint device conforms to the flammability resistance requirements of the standard. A commercial business that installs the head restraint on new or used vehicles would be subject to statutory considerations that affect whether the business may install your product on a vehicle without violating the Safety Act. Section 108(a)(2)(A) of the Act states: '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 or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard ...' This section requires manufacturers, distributors, dealers or motor vehicle repair businesses (i.e., any person holding him or herself out to the public as in the business of repairing motor vehicles or motor vehicle equipment for compensation) installing your head restraint device on new or used vehicles to ensure that the addition of the apparatus would not negatively affect the compliance of any component or design on a vehicle with applicable Federal safety standards. For example, the commercial entity must ensure that the addition of the device does not degrade from the safety provided by flammable-resistant materials in the vehicle's interior compartment which have been installed in accordance with Standard No. 302. Installation of rapidly burning materials could vitiate the compliance of the materials which were present in the vehicle at the time of its sale to the first consumer and were certified as meeting FMVSS No. 302. Section 109 of the Act specifies a civil penalty of up to $1,000 for each violation of /108. However, the prohibitions of /108(a)(2)(A) do not apply to the actions of a vehicle owner in adding to or otherwise modifying his or her vehicle. Thus, a vehicle owner would not violate the Safety Act by installing the head restraint, even if doing so would negatively affect some safety feature in his or her vehicle. In addition to the materials described above, I am also enclosing a Federal Register notice (53 FR 50047) that NHTSA issued on December 13, 1988, proposing to extend the applicability of Standard No. 202 to light trucks and vans. NHTSA has proposed to make this extension effective September 1, 1991. We expect to announce the agency's next step in the rulemaking proceeding by this fall. Please feel free to contact us if you have further questions. Sincerely, Stephen P. Wood Acting Chief Counsel Enclosures";
