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.

Aurora, CO 80012

Dear Ms. Thomas:

This responds to your letter asking about safety regulations for a device you call a "CarMobile." The CarMobile is a type of strap to which three rings are sewn. The CarMobile attaches by "velcro" straps to the handrails located at the top of the interior rear car doors. You state that "Toys would be hung from the rings, so that babies and toddlers can play with them as they dangle in front of their carseats."

By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the authority to issue 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. Instead, each manufacturer is responsible for "self-certifying" that its products meet all applicable safety standards. The agency periodically tests vehicles and items of equipment for compliance with the standards.

In response to your question, there is currently no Federal motor vehicle safety standard (FMVSS) that directly applies to the product you wish to manufacture. However, 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 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 CarMobile 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. NHTSA's safety standard for built-in child restraint systems (Standard 213) specifies requirements that ensure that the area surrounding a child in a built-in restraint is free from objects that could injure a child's head in a crash. If the CarMobile's cord and rings cause the vehicle with the built-in restraint to no longer comply with Standard 213, any of the aforementioned parties installing the CarMobile may have violated '30122.

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, and would discourage them from hanging toys or other objects in front of a seated child that could injure the child in a crash. We also wish to point out that any kind of ribbon or line that can wrap around the neck of a child in a crash poses a potential risk of strangulation in a crash. You should consider these and any other relevant safety concerns when designing the CarMobile and when instructing consumers how to use the device.

I hope this is helpful. If you have any other questions, please contact Deirdre Fujita of my staff at this address or by phone at (202) 366-2992.

John Womack Acting Chief Counsel

Dear Ms. O'Cordan:

This responds to your question about whether any Federal motor vehicle safety standard (FMVSS) applies to glass used in a travel trailer. You stated that your law office was investigating an accident in which an individual was injured by glass of such a vehicle.

Please be aware that no FMVSS applies to the glazing (the term the agency uses for glass) in trailers. The agency has issued one standard, FMVSS No. 205, Glazing Materials, (49 CFR '571.205), which applies to glazing in some motor vehicles. However, this standard does not apply to glazing in trailers, which our regulations define as "a motor vehicle with or without motive power, designed for carrying persons or property and for being drawn by another motor vehicle" (49 CFR '571.3).

You may wish to contact the State of Wisconsin about the regulation of glass in trailers. The State has the authority to regulate the operation and modification of vehicles by their owners. Wisconsin may have used this authority to issue regulations about glazing in travel trailers.

I hope this information is helpful. Please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992 if you have any further questions or need additional information.

Sincerely,

John Womack Acting Chief Counsel

This responds to your letter asking about safety 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,

Dear Mr. Matsui:

This responds to your letter of June 23, 1995, asking questions about neon high mounted stop lamps.

The National Highway Traffic Safety Administration answered these questions in the preamble to a notice of proposed rulemaking that was published on June 19, 1995. We assume that you had not received it by the 23rd, and enclose a copy for your information.

You will see (center column, page 31940) that Federal Motor Vehicle Safety Standard (FMVSS) No. 108 allows neon tubes as light sources for the center highmounted lamp. Under our interpretation of paragraph S5.1.1.16, FMVSS No. 108 also allows testing of a neon lamp with or without its ballast, in accordance with the directions of that paragraph.

If you have any questions, you may refer them to Taylor Vinson of this Office.

Sincerely,

John Womack Acting Chief Counsel

Mr. C.H. Je
Doosan Corporation
Pusan Branch
5KA-50
Chungang-dong
Chungku, Pusan
KOREA

Dear Mr. Je:

This responds to your letter identifying your company as a "trading company" and asking for permission from the U.S. Department of Transportation to sell air bags in the United States. As I explain below, no such permission is necessary, but there are some requirements you should be aware of before you begin importing air bags.

I am pleased to have this opportunity to explain our laws and regulations to you. The National Highway Traffic Safety Administration (NHTSA) is authorized under Title 49, Chapter 301 of the U.S. Code to issue Federal Motor Vehicle Safety Standards for new motor vehicles and new items of motor vehicle equipment. NHTSA, however, does not approve motor vehicles or motor vehicle equipment, nor do we endorse any commercial products or conduct pre-sale testing of any commercial products. Instead, Chapter 301 establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards. I note that the term "manufacturer" is defined in 49 U.S.C. '30102(5)(B) as "a person . . . manufacturing or assembling motor vehicles or motor vehicle equipment [or] importing motor vehicles or motor vehicle equipment for resale." (Emphasis added.)

NHTSA has exercised its authority under Chapter 301 to establish Standard No. 208, Occupant Crash Protection (49 CFR '571.208). Standard No. 208 requires, among other things, that passenger cars provide automatic crash protection. Also, a phase-in of automatic crash protection requirements for light trucks is in progress. Vehicles equipped with automatic crash protection protect their occupants by means that require no action by vehicle occupants. Compliance with the automatic crash protection requirements of Standard No. 208 is

determined in a dynamic crash test. That is, a vehicle must comply with specified injury criteria, as measured on a test dummy, when tested by this agency in a 30 mph barrier crash test.

At this time, manufacturers are not required to use a specific method of automatic crash protection to meet the requirements of Standard No. 208. Instead, each automobile manufacturer is allowed to select the particular method for the automatic crash protection installed in its vehicles. The two types of automatic crash protection currently offered on new passenger cars are automatic safety belts (which help to assure belt use) and air bags (which supplement safety belts and offer some protection even when safety belts are not used). However, a recent amendment of Standard No. 208 makes air bags mandatory in all passenger cars and light trucks by the late 1990's.

Please note that the automatic crash protection requirement applies to the performance of the vehicle as a whole, instead of setting requirements for the air bag as an individual item of equipment. This approach permits vehicle manufacturers to "tune" the performance of the air bag to the crash pulse and other specific attributes of each of their vehicle models. However, this approach also means that the Federal standards do not specify specific performance attributes for air bags such as inflated dimensions, actuation time, and the like.

It is unclear from your letter if the air bags you wish to import will be sold to manufacturers for installation in new vehicles or if the air bags will be sold as replacement air bags or retrofit air bags for vehicles which do not have air bags as original equipment. If the air bags are sold to manufacturers for installation in new vehicles, the vehicle manufacturer is required to certify that the vehicle complies with all applicable safety standards, including Standard No. 208. If the air bag is added to a previously certified new motor vehicle prior to its first sale, the person who modifies the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify that, as altered, the vehicle continues to comply with all of the safety standards affected by the installation of the air bag. (See 49 CFR Part 567.7.)

While most of Standard No. 208's requirements are expressed in terms of the performance of the vehicle as a whole and apply only to new vehicles and not to aftermarket equipment, there is one exception to this. Pressure vessels and explosive devices for use in air bag systems must comply with section S9 of Standard No. 208 whether they are part of a new motor vehicle or are aftermarket equipment. Therefore, the manufacturer of these items must certify that they comply with the requirements of S9 of Standard No. 208.

Another Federal requirement that would affect the device if it were installed in a used vehicle, either as a replacement or retrofit air bag, is the "make inoperative" prohibition in U.S. Code Section 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 Federal motor vehicle safety standard . . .

The "make inoperative" provision would prohibit a commercial business from installing an aftermarket air bag in a manner that would negatively affect the vehicle's compliance with Standard No. 208.

You should also note that a replacement or retrofit air bag would be considered "motor vehicle equipment" within the meaning of the U.S. Code. Therefore, if the air bag contained a defect (either in manufacture, design, or performance) that relates to motor vehicle safety, the manufacturer would be required to conduct a recall campaign to notify owners and to remedy the defect free of charge. You should be aware that recently the manufacturer of an aftermarket air bag that did not provide crash protection benefits to vehicle occupants ceased offering its air bags following a NHTSA investigation. In addition, NHTSA provided information to the Federal Trade Commission concerning the claims made by the manufacturer in its advertising. We suggest you carefully review the manufacturer's test data on the devices you are considering importing to assure yourself that the air bag would afford adequate protection to vehicle occupants in crashes and that the claims made in the company's advertising are true.

I have enclosed an information sheet that identifies relevant Federal statutes and NHTSA standards and regulations affecting motor vehicle and motor vehicle equipment manufacturers, and explains how to obtain copies of these materials. Please note the regulations concerning manufacturer identification and designation of agent.

I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

Mr. Paul Frink
Engineering Manager
Avionic Structures, Inc.
1429 North State College Boulevard
Anaheim, CA 92806

Dear Mr. Frink:

This responds to your letter and telephone call asking several questions about Federal Motor Vehicle Safety Standard (FMVSS) No. 206, Door Locks and Door Retention Components (49 CFR 571.206).

Your letter stated that your company manufactures a door and frame system designed for installation on a "recreational motor home," which you described as a self-propelled, self-contained recreational vehicle seating six and with a gross vehicle weight rating of under 10,000 pounds. The door system is installed on the right front side of the vehicle and is the primary means of ingress/egress. You stated that the door's latch/striker assembly is purchased from Tri-Mark Corporation, and that Tri-Mark assures you that the latch/striker assembly conforms to the requirements of FMVSS No. 206. You ask what the classification of the vehicle would be and whether FMVSS No. 206 would apply to the door in question.

By way of background information, 49 U.S.C. 30101, et seq. authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal motor vehicle safety standards applicable to new motor vehicles and new items of motor vehicle equipment. The statute establishes a self-certification system in which manufacturers certify that their products comply with all applicable FMVSSs. This agency ensures compliance by purchasing vehicles and/or equipment in the retail market and testing them as set forth in the applicable standards. If the vehicle or equipment is found to meet the requirements of the standards, no further action is taken. If the vehicle or equipment fails to meet the standards, the manufacturer is responsible for correcting the noncompliance(s) at no cost to the purchaser. NHTSA also investigates defects relating to motor vehicle safety. If a manufacturer or NHTSA determines that a safety-related defect exists, the manufacturer must notify purchasers of its product and remedy the defect free of charge.

For the purposes of the FMVSSs, NHTSA classifies motor vehicles as passenger cars, multipurpose passenger vehicles (MPVs), trucks, buses, motorcycles, and trailers. From your description, the vehicle concerned would be classified as an MPV, which is defined in the definitions section of our FMVSSs (49 CFR 571.3; see enclosed) as a motor vehicle "designed to carry 10 persons or less which is constructed either on a truck chassis or with special features for occasional off- road operation."

You first ask about the classification of the vehicle and whether FMVSS No. 206 would apply. FMVSS No. 206 (copy enclosed) applies to passenger cars, MPVs and trucks. Since the vehicle on which your door and frame system will be installed is an MPV, the standard would apply to the vehicle. The standard requires that, with certain exceptions not applicable here, components on any side door leading directly into a compartment containing one or more seating accommodations must comply with the requirements of the standard (see S4 of FMVSS No. 206). The door in question meets this description of S4. According to your letter, there is a step area extending from the door opening into the coach and the passenger seat closest to the door is behind this step area. The presence of the step area does not negate the fact that the door in question leads directly into a compartment that contains passenger seating accommodations. Thus, the components of the door must comply with the requirements of FMVSS 206.

To clarify your understanding of the applicability of FMVSS No. 206, the standard applies to new completed vehicles. Therefore, it would be the vehicle manufacturer who would "certify" compliance with the standard, not the various manufacturers of the components of the door lock system. Sometimes the vehicle manufacturer will rely on the assurances of the suppliers, such as Avionic and Tri-Mark, that the components conform to the requirements of the applicable standards, in making the certification to FMVSS No. 206. However, the vehicle manufacturer is ultimately responsible for ensuring that the vehicle complies with FMVSS No. 206, and therefore must determine whether those assurances are bona fide.

Also enclosed for your information are fact sheets issued by this agency entitled "Information for New Manufacturers of

Motor Vehicles and Motor Vehicle Equipment" and "Where to Obtain NHTSA's Safety Standards and Regulations," respectively. I hope this information is helpful to you. Should you need any additional information or have any further questions, please feel free to contact Mr. Myers of my staff at this address or at (202) 366-2992.

Manager, Vehicle Regulations
Volkswagen of America, Inc.

Auburn Hills, MI 48326

Dear Mr. Haenchen:

This responds to your follow up request for an interpretation of marking requirements in 49 CFR part 541 Federal Motor Vehicle Theft Prevention Standard, for high theft vehicle lines' replacement parts. I apologize for the delay in our response. We reiterate our position in a July 1, 1994 letter to you, that Volkswagen is required to continue marking replacement parts of the Corrado line, in model year 1995 and thereafter. The reason for this position follows.

In your earlier request for an interpretation, you explained that the Volkswagen Corrado line, a high theft line, was parts marked (pursuant to 49 CFR part 541) in model years (MYs) 1990 through 1994. For MY 1995, NHTSA granted a part 543 exemption from parts marking for the Corrado line, based on the inclusion of an approved antitheft device as standard equipment on all models in the Corrado line. (58 FR 28434, May 13, 1993). However, you informed us in your letter that the Corrado will not be sold in the United States for MY 1995.

In a July 1, 1994 interpretation letter to you, we determined that since Volkswagen will not sell the exempted MY 1995 Corrado line with the antitheft device, in the United States, the part 543 exemption would not apply, and Volkswagen must continue to mark the replacement parts for the Corrado line.

In your follow up letter, you wrote that the MY 1994 Corrado line has, as standard equipment, the antitheft device that was the subject of the part 543 exemption for MY 1995. You state that since the Corrado line with the approved antitheft device was sold in the United States, replacement parts for the Corrado line should not be subject to marking in MY 1995 and thereafter.

We do not agree with your position. 49 CFR '543.7(d) specifies that part 543 exemptions apply only to lines that: (1) are the subject of the grant; and (2) are equipped with

the antitheft device on which the line's exemption was based. The MY 1994 Corrado line does not meet the first condition, i.e., it is not the subject of a grant of an exemption from parts marking. The part 543 exemption for the Corrado line begins with MY 1995. (See 58 FR 28434). You have earlier written that no MY 1995 Corrado line with the exempted device, will be sold in the U.S. As stated in our July 1, 1994 letter, since no exempted line, equipped with the antitheft device will be sold in the U.S., Volkswagen must continue to mark any Corrado replacement parts, subject to part 541, as long as the replacement parts are offered for sale in the U.S.

I hope that this information is helpful. If you have any further questions, please contact Dorothy Nakama of my staff at (202) 366-2992.

P.O. Box 981
Odessa, FL 33556-0981

Dear Mr. Winzkowski:

This responds to your letter about a manufacturer's certification responsibilities under Federal Motor Vehicle Safety Standard No. 205, Glazing materials (49 CFR '571.205; copy enclosed). You state that you are a United States-based subsidiary of a German automotive sunroof manufacturer. You are having problems explaining to the German authorities the differences between the certification requirements of the two countries and request a letter explaining that the U.S. uses a self-certification procedure.

I am pleased to provide this information. As you know, every item of glazing for use in motor vehicles that is sold in or imported into this country must be certified as complying with FMVSS No. 205. This standard sets forth both performance and labeling requirements that must be satisfied by the automotive glazing. In enforcing its safety standards, the National Highway Traffic Safety Administration (NHTSA), which is part of the U.S. Department of Transportation, does not follow the European practice of requiring the manufacturer of motor vehicle equipment to deliver an item of the equipment to specified institutes for testing before the product can be sold. Instead, as required by the U.S. Congress, the manufacturer "self-certifies" that each of its items of motor vehicle equipment fully satisfies all requirements of the applicable Federal motor vehicle safety standards.

Thus, each item of automotive glazing is self-certified by its manufacturer as complying with FMVSS No. 205. NHTSA does not require that the manufacturer's certification be based on a specified number of tests of the glazing or on any tests at all. Under the statute, the agency only requires that the certification be made with the exercise of "due care" on the part of the manufacturer. It is up to the manufacturer to determine what data, test results, or other information is needed to enable it to certify that the glazing complies with Standard No. 205. We do recommend, however, that a manufacturer selling its glazing

in the United States for the first time test those products, according to the test procedures specified in Standard No. 205. Once the manufacturer has determined that its glazing complies with the requirements of Standard No. 205, it certifies that compliance by marking the glazing with the symbol DOT, as specified in section S6 of Standard No. 205.

You specifically asked for verification that "no US DOT testing or certification is conducted when DOT numbers are assigned to manufacturers." The "DOT number" to which you refer is the manufacturer's code mark that is assigned by NHTSA on request of the glazing manufacturer (S6.2 of FMVSS No. 205). Your understanding is correct. NHTSA does not test glazing products or review manufacturers' compliance data prior to or as a condition for assigning a manufacturer's code mark pursuant to S6.2 of Standard No. 205.

I hope you find this information helpful. If you have any other questions, please contact Mr. Marvin Shaw of my staff at (202) 366-2992.

This responds to your letter asking about how this agency's regulations might apply to your product. I apologize for the delay in sending this letter. You explained in a telephone conversation with Paul Atelsek of this office that your product is an emergency kit the size of an "oversize notebook." The kit contains a radio. In completing your design, you are considering whether to attach it to the back side of the front seats or under those seats. You asked whether the National Highway Traffic Safety Administration (NHTSA) has any regulations as to the distance that must be kept clear between the back side of the driver's seat and the back seat. You are considering marketing the kit for passenger cars and light trucks through retail outlets, and possibly also through automobile dealerships as an optional accessory.

The short answer to your question is that, while there are no regulations concerning clearance between the front and back seats, there are Federal requirements that may affect the sale of this product. I am pleased to have this opportunity to explain our regulations. I am also enclosing a copy of a fact sheet titled "Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment."

By way of background information, NHTSA is authorized to issue Federal motor vehicle safety standards (FMVSS's) for new motor vehicles and new items of motor vehicle equipment. These are contained in title 49, part 571 of the Code of Federal Regulations. As you recognize in your letter, your safety kit is an accessory and thus an item of motor vehicle equipment.

While your emergency kit is an item of motor vehicle equipment, NHTSA has not issued any standards for such an item. Nevertheless, there are other provisions of law that may affect the manufacture and sale of your product. Installation of your product on the back of front seats could have an impact on compliance with Standard No. 201, Occupant

protection in interior impact. S3.2 of that standard basically requires that seat backs have a certain amount of cushioning to provide protection when struck by the head of rear seat passengers during a crash. If your emergency kit were installed so that a hard object (e.g., the radio) contained within it were to be struck by the head, the requisite amount of cushioning might not be achieved. We note that there are no safety standards regulating the underside of the seats, which you have said is another interior space where you are considering mounting the emergency kit.

Which legal requirements apply depends on how your product is marketed. If your product were installed by a vehicle manufacturer as original equipment, the vehicle manufacturer would have to certify that the vehicle with the emergency kit installed complies with all FMVSS's, including Standard No. 201.

A commercial business that installs your emergency kit would also be subject to provisions of the U.S. Code that affect modifications of new or used vehicles. Section 30122(b) of Title 49 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 Federal motor vehicle safety standard . . .

This means that a manufacturer, distributor, dealer, or motor vehicle repair business must not install your device if the system renders inoperative the vehicle's compliance with the FMVSS's. For instance, compliance with Standard No. 201 might be degraded if the emergency kit were mounted in front of rear seat passengers. Any violation of this "make inoperative" prohibition would subject the violator to a potential civil penalty of up to $1,000 for each violation.

The "make inoperative" prohibition does not apply to modifications that vehicle owners make to their own vehicles. Thus, Federal law would not apply in situations where individual vehicle owners install your emergency kit in their own vehicles, even if the installation were to result in the vehicle no longer complying with the safety standards. However, NHTSA encourages vehicle owners not to degrade any safety device or system installed in their vehicles. In addition, individual States have the authority to regulate modifications that individual vehicle owners may make to their vehicles, so you might wish to consult State regulations to see whether your device would be permitted.

You as the product's manufacturer are subject to the requirements in sections 30118-30122 of Title 49 of the U.S. Code concerning the recall and remedy of products with defects related to motor vehicle safety. In the event that the manufacturer or NHTSA determines that the product contains a safety related defect, the manufacturer would be responsible for notifying purchasers of the defective equipment and remedying the problem free of charge.

I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Mr. Atelsek at this address or by telephone at (202) 366-2992.

Sincerely,

Philip R. Recht Chief Counsel

Mr. Richard Kreutziger Executive Director New York School Bus Distributors Association 102 Grace Street Penn Yan, NY 14527

Dear Mr. Kreutziger:

This responds to your facsimile transmittal letter to me of July 19, 1994.

Your letter referred to Federal Motor Vehicle Safety Standard (FMVSS) No. 217, Bus Emergency Exits and Window Retention and Release (49 CFR 571.217), and asked whether emergency exits on school buses with a gross vehicle weight rating (GVWR) of less than 4,536 kilograms (10,000 pounds) and a passenger capacity of 2 to 16 seated and/or wheelchair positions, are required to be outlined with retroreflective tape as specified in paragraph S5.5.3(c) of the standard.

In 49 CFR 571.3, this agency defines a bus as a motor vehicle, except a trailer, designed to carry more than 10 persons, and further defines a school bus as

[A] bus that is sold, or introduced in interstate commerce, for purposes that include carrying students to and from school or related events, but does not include a bus designed and sold for operation as a common carrier in urban transportation.

Whether or not a vehicle is a school bus, therefore, depends on its use (transporting the specified students) and seating capacity (more than 10), and not GVWR. Accordingly, if the seating capacity of a vehicle is 10 or less, it is not a bus and likewise not a school bus, regardless of use or GVWR. Such a vehicle would not be required to comply with the requirements of FMVSS No. 217.

Vehicles meeting the definition of school bus would be subject to the requirements of FMVSS No. 217. Section S5.5 of the standard, Emergency Exit Identification, specifies the marking

requirements for emergency exits on all buses. Sections S5.5.1 and S5.5.2 apply to non-school buses, while section S5.5.3 applies to all school buses, without regard to GVWR.

Paragraph S5.5.3(c) provides:

Each opening for a required emergency exit shall be outlined around its outside perimeter with a minimum 3 centimeters wide retroreflective tape, either red, white, or yellow in color, that when tested under the conditions specified in S6.1 of 571.131, meets the criteria specified in Table 1.

We would like to emphasize two points with regard to your letter. The first is that only those emergency exits that are required by the standard are subject to this provision. Extra emergency exits added as options are encouraged, but not required, to be outlined with the tape. The other point is one that I made in a May 18, 1994 letter to you. A technical amendment is pending publication which will amend the size requirement for the width of the retroreflective tape, from a minimum of 3 centimeters (cm.) to a minimum of 2.5 cm. That amendment is necessary because retroreflective tape is not commercially available in 3 cm. widths. Until the correction is issued, NHTSA will not take enforcement measures regarding tape width size against a manufacturer who uses one inch wide (minimum 2.5 cm.) retroreflective tape.

In closing, bear in mind that all school buses are required to have a specified number of emergency exits, the number and location of which depend on the seating capacity of the vehicle, regardless of the GVWR, and all required emergency exits must be outlined with the retroreflective tape.

I hope this information is helpful to you. Should you have any further questions or need any additional information, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992.

Sincerely,

John Womack Acting Chief Counsel ref:217 d:8/26/94
